Protestantism
Ideology | Active
1520 CE to 2057 CE
Protestantism is a form of Christian faith and practice that originates with the Protestant Reformation, a movement against what its followers consider to be errors in the Roman Catholic Church.
It is one of the three major divisions of Christendom, together with Roman Catholicism and Eastern Orthodoxy.
Anglicanism is sometimes considered to be independent from Protestantism.
The term derives from the letter of protestation from Lutheran princes in 1529 against an edict condemning the teachings of Martin Luther as heretical.
With its origins in Germany, the modern movement is popularly considered to have begun in 1517 when Luther publishes The Ninety-Five Theses as a reaction against abuses in the sale of indulgences, which purported to offer remission of sin to their purchasers.
Although there were earlier breaks from or attempts to reform the Roman Catholic Church—notably by Peter Waldo, Arnold of Brescia,Girolamo Savonarola, John Wycliffe, and Jan Hus—only Luther succeeds in sparking a wider, lasting movement.All Protestant denominations reject the notion of papal supremacy over the Church universal and generally deny the Roman Catholic doctrine of transubstantiation, but they disagree among themselves regarding the real presence of Christ in the Eucharist.
The various denominations generally emphasize the priesthood of all believers, the doctrine of justification by faith alone (sola fide) rather than by or with good works, and a belief in the Bible alone (rather than with Catholic tradition) as the highest authority in matters of faith and morals (sola scriptura).
The "Five solae" summarize the reformers' basic differences in theological beliefs in opposition to the teaching of the Roman Catholic Church of the day.
Protestantism spreads on the European continent during the sixteenth century.
Lutheranism spreads from Germany into its surrounding areas, Denmark, Norway, Sweden, Prussia, Latvia, Estonia, and Iceland, as well as other smaller territories.
Reformed churches are founded primarily in Germany and its adjacent regions, Hungary, the Netherlands, Scotland, Switzerland, and France by such reformers as John Calvin, Huldrych Zwingli, and John Knox.
Arminianism gains supporters in the Netherlands and parts of Germany.
In 1534, King Henry VIII puts an end to all papal jurisdiction in England after the Pope fails to annul his marriage to Catherine of Aragon; this opens the door to reformational ideas, notably during the following reign of Edward VI, through Thomas Cranmer, Richard Hooker, Matthew Parker and other theologians.
There are also reformational efforts throughout continental Europe known as the Radical Reformation—a response to perceived corruption in both the Roman Catholic Church and the expanding Magisterial Reformation led by Luther and various other reformers—which give rise to Anabaptist, Moravian, and other Pietistic movements.
In later centuries, Protestants develop their own culture, which makes major contributions in education, the humanities and sciences, the political and social order, the economy and the arts, and other fields.
Collectively encompassing more than nine hundred million adherents, or nearly forty percent of Christians worldwide, Protestantism is present on all populated continents.
The movement is more divided theologically and ecclesiastically than either Eastern Orthodoxy or Roman Catholicism, lacking both structural unity and central human authority.
Some Protestant churches do have a worldwide scope and distribution of membership (notably, the Anglican Communion), while others are confined to a single country, or even are solitary church bodies or congregations (such as the former Prussian Union of churches).
Nondenominational, evangelical, independent and other churches are on the rise, and constitute a significant part of Protestant Christianity.
An exact number of Protestant denominations is difficult to calculate and depends on definition.
Nevertheless, most Protestants are members of just a handful of denominational families: Adventism, Anglicanism, Baptist churches, Reformed churches, Lutheranism, Methodism, and Pentecostalism.

North Europe (1396–1539 CE)
Kalmar Union, Hanseatic Hubs, and Tudor Beginnings
Geography & Environmental Context
North Europe stretched from the Baltic to the North Atlantic, encompassing the forested and maritime worlds of Scandinavia, the Baltic states, and the British–Irish archipelago.
Northeast Europe—Sweden, Finland, Lithuania, Latvia, Estonia, eastern Denmark, and eastern Norway—formed the heart of the Baltic world, where forests, lakes, and grain plains fed into Hanseatic trade.
Northwest Europe—England, Scotland, Ireland, Wales, Iceland, the Faroes, and the Atlantic coasts of Norway and Denmark—looked westward toward fisheries and emerging Atlantic routes. Together, they linked the inland forests and plains to the open seas that defined early modern northern power.
Climate & Environmental Shifts
The Little Ice Age deepened winter severity and shortened growing seasons.
-
Baltic region: Long freezes closed harbors; floods and late thaws alternated with droughts in interior plains.
-
Scandinavia & Finland: Harvests shrank; forests and fisheries provided crucial fallback resources.
-
North Atlantic fringe: Harsher storms and sea-ice reached further south, disrupting cod and herring cycles but enriching fisheries in better years.
-
Britain & Ireland: Cooler, wetter decades challenged crops but spared maritime trade, as fisheries and livestock compensated for shortfalls.
Subsistence & Settlement
-
Baltic lands: Rye, barley, and oats dominated; forests yielded furs, timber, tar, and honey; iron mining in Bergslagen (Sweden) expanded.
-
Scandinavia & Denmark: Mixed grain and stock herding supported towns like Stockholm, Oslo, and Copenhagen.
-
British Isles: England’s open fields produced wheat, rye, and barley; uplands in Scotland, Wales, and Ireland focused on oats, grazing, and dairying; peat and woodland provided vital fuel.
-
Iceland & Faroes: Dependent on sheep, fish, and seabirds, exporting dried cod and wool to Bergen and Hanseatic merchants.
Urban growth centered on London, Stockholm, Copenhagen, Riga, and Tallinn—ports uniting inland grain and iron with sea commerce.
Technology & Material Culture
-
Agriculture: Wooden plows, iron blades, and watermills; three-field rotations in Baltic plains and open-field farming in England.
-
Maritime: Cogs, hulks, and evolving caravels carried timber, grain, and fish; clinker-built vessels remained common in fjords and islands.
-
Industry: Swedish ironworks, English cloth finishing, and Hanseatic shipyards drove regional exchange.
-
Architecture: Brick Gothic churches and fortresses in the Baltic; Perpendicular Gothic cathedrals in England; stave-church legacies in Norway; fortified tower houses in Ireland and Scotland.
-
Print & craft: Printing spread to London, Paris, Copenhagen, and Stockholm after 1476, fostering literacy and trade in books.
Movement & Interaction Corridors
-
Hanseatic League: From Lübeck to Riga and Tallinn, Baltic trade moved furs, tar, wax, and grain outward, bringing textiles, salt, and wine inward.
-
Kalmar Union (1397): United Denmark, Norway, and Sweden under one monarch; internal rebellion and civil wars foreshadowed its collapse.
-
Lithuania & Poland: The Polish–Lithuanian union (1386) extended from the Baltic to the steppe, linking Europe to Muscovy’s frontier.
-
British & Irish seas: Wool, cloth, and salt fish moved between London, Dublin, Bristol, Edinburgh, and continental ports.
-
Atlantic ventures: Bristol merchants probed western seas; John Cabot’s voyage (1497) revealed the cod-rich coasts of Newfoundland.
-
Scandinavian routes: Bergen’s Hanse convoys and Jutland’s cattle exports tied the Atlantic rim to the Baltic core.
Cultural & Symbolic Expressions
-
Faith & reform: Catholic orthodoxy prevailed, though reformist ideas spread via universities and trade. The Lutheran Reformation took root first in Sweden (under Gustav Vasa, 1520s) and Denmark–Norway (after 1536).
-
Literature & learning: Swedish and Danish chronicles, Gaelic bardic poetry, Icelandic sagas, and English and Scots verse (e.g., Dunbar, Henryson) flourished.
-
Urban culture: Baltic guilds sponsored altarpieces and public art; English confraternities built hospitals and chapels; Hanseatic merchants endowed churches across ports.
-
Law & monarchy: English common law matured; Scottish and Danish kings strengthened bureaucracies; Gaelic Brehon law persisted in Ireland.
Environmental Adaptation & Resilience
-
Diversified subsistence: Grain shortages offset by fishing, forestry, and livestock.
-
Storage & trade: Hanseatic and English granaries redistributed food in famine years.
-
Construction: Log and turf houses insulated against cold; seawalls and dikes secured coasts.
-
Mobility: Transhumance, timber floating, and coastal shipping ensured resource flow across fragmented geographies.
Technology & Power Shifts (Conflict Dynamics)
-
Scandinavia:
-
Kalmar Union revolts (1430s–1520s) led to Sweden’s independence under Gustav Vasa (1523) and the start of Lutheran reform.
-
Denmark–Norway retained the Atlantic isles; the Count’s Feud (1534–1536) ended with royal consolidation and Protestant victory.
-
-
Baltic & Steppe:
-
The Livonian Order ruled Estonia and Latvia under Hanseatic influence, declining under pressure from Muscovy.
-
Lithuania fought Moscow’s expansion, maintaining autonomy in the Polish–Lithuanian commonwealth.
-
Teutonic Prussia weakened after Tannenberg (1410), becoming a Polish fief.
-
-
British Isles:
-
The Hundred Years’ War’s close (1453) redirected England inward.
-
Wars of the Roses (1455–1487) culminated in Tudor rule under Henry VII.
-
Flodden (1513) crushed Scottish arms; Ireland remained divided between the English Pale and Gaelic lordships.
-
-
Maritime shifts: Naval gunnery, enclosed shipyards, and state fleets emerged, notably under the Tudors and Danes, signaling northern Europe’s coming naval ascendancy.
Transition (to 1539 CE)
By 1539, North Europe stood divided yet ascendant:
The Hanseatic League waned but its maritime legacy endured; Sweden and Denmark–Norway entered the Protestant era; Lithuania faced the growing might of Muscovy; and the British Isles, stabilized under the Tudors, turned toward the Atlantic.
Iceland and the Faroes remained fishing outposts; the Baltic still pulsed with trade in grain, tar, and timber. Across forests, fjords, and sea-lanes, resilience under cold skies forged the region’s next transformation—from medieval borderlands to early modern maritime powers.
Northeast Europe (1396–1539 CE): Kalmar Union, Hanseatic Hubs, and Baltic Frontiers
Geographic & Environmental Context
The subregion of Northeast Europe includes Sweden, Finland, Lithuania, Latvia, Estonia, eastern Denmark (with Copenhagen), eastern Norway (with Oslo), and the Kaliningrad enclave. Anchors spanned the Baltic Sea and Gulf of Finland, the Bothnian Gulf, the Scandinavian lake–forest interior, and the Lithuanian–Livonian plains. Forests, lakes, and rivers fed into the Baltic maritime corridor, while upland pastures, iron-bearing districts, and fishing zones shaped inland economies.
Climate & Environmental Shifts
The Little Ice Age deepened seasonal extremes.
-
Winters: longer freezes locked harbors and rivers, delaying trade;
-
Summers: shorter, sometimes wet, affecting grain harvests in Sweden, Finland, and Livonia;
-
Forests & lakes: supplied furs, timber, and fish to buffer poor grain years.
Sea ice spread widely in severe winters, but milder decades allowed sustained shipping across the Baltic.
Subsistence & Settlement
-
Scandinavia (Sweden, Finland, Norway east): Rye, barley, oats, and peas were staples; fishing and stock herding were critical supplements; iron mining grew in Bergslagen (Sweden).
-
Denmark (eastern provinces): Grain, dairy, and fishing supported Copenhagen, an emerging royal hub.
-
Baltic states (Lithuania, Latvia, Estonia): Cereal farming (rye, barley), cattle herding, flax, and honey; coastal towns drew supplies from inland peasants.
-
Kaliningrad (Prussian coast): Mixed farming with rye and livestock; amber collecting continued.
Technology & Material Culture
-
Agriculture: wooden plows, iron-tipped tools, watermills; three-field rotations in Baltic plains.
-
Mining & craft: Swedish ironworks expanded, producing bars for Hanseatic trade.
-
Maritime: cogs and hulks carried timber, tar, grain, and iron; Danish and Swedish shipwrights innovated in response to naval rivalries.
-
Architecture & art: Brick Gothic churches, Hanseatic warehouses, and castle fortresses (Tallinn, Riga, Stockholm, Vilnius); altarpieces and icon painting reflected Catholic and Orthodox patronage.
Movement & Interaction Corridors
-
Hanseatic League: Lübeck, Tallinn, Riga, and Stockholm tied the region into North Sea–Baltic trade; furs, timber, wax, and grain moved outward, textiles and salt inward.
-
Kalmar Union (1397): Linked Denmark, Norway, and Sweden under one crown; tensions between Danish monarchs and Swedish nobility fueled civil wars.
-
Lithuania: Stretched from Baltic to Black Sea; in union with Poland (from 1386) but retained distinct identity; trade routes through Vilnius connected to Muscovy.
-
Livonian Order: German knights ruled Estonia and Latvia, defending ports while exploiting peasantry.
-
Novgorod & Muscovy: Baltic trade drew in Russian fur and wax via Novgorod until its annexation by Moscow in 1478.
Cultural & Symbolic Expressions
-
Catholicism: Dominant in Denmark, Sweden, Norway, and Baltic towns; monasteries, cathedrals, and feast calendars organized social life.
-
Orthodoxy: Endured in eastern Lithuania and among Russian enclaves; Pskov and Novgorod influenced nearby Baltic cultures.
-
Local traditions: Folk epics, runo-songs, and sagas persisted in Finland and Karelia; seasonal rites tied to agriculture and fishing.
-
Art & letters: Lithuania fostered chronicles; Swedish and Danish courts commissioned sagas and chronicles; German-language urban culture dominated Hanseatic towns.
Environmental Adaptation & Resilience
-
Grain storage: Granaries and trade surpluses in Lübeck and Riga redistributed food in famine.
-
Diversification: Fishing, forestry, hunting, and livestock offset poor harvests.
-
Architecture: Log houses and turf-roofed structures insulated against cold; fortified towns stored supplies.
-
Mobility: Seasonal herding, timber floating, and coastal shipping buffered communities against local scarcity.
Technology & Power Shifts (Conflict Dynamics)
-
Kalmar Union: Swedish nobles resisted Danish dominance; Engelbrekt rebellion (1430s) and wars in the late 15th century destabilized the union.
-
Sweden: Broke definitively from Denmark in 1523 under Gustav Vasa, founding a hereditary monarchy and initiating the Lutheran Reformation.
-
Norway: Remained bound to Denmark until the 19th century, with Oslo as an eastern hub.
-
Lithuania: Fought Muscovy on its eastern frontier; preserved autonomy in the Polish–Lithuanian union.
-
Livonian Order: Contested with Russians and Lithuanians; relied on Hanseatic allies for survival.
-
Kaliningrad coast (Prussia): Under Teutonic Knights, weakened after defeat at Tannenberg/Grunwald (1410), shifting toward Polish suzerainty.
Transition
By 1539 CE, Northeast Europe was fractured but dynamic: the Kalmar Union was collapsing, Sweden independent under Gustav Vasa and entering Lutheran reform; Lithuania remained powerful but pressured by Muscovy; Livonia survived precariously between neighbors; Hanseatic ports still dominated Baltic trade, though in decline. Orthodox, Catholic, and Protestant frontiers overlapped across the region, foreshadowing wars of confession and imperial competition.
The Church's incomes and possessions are instead redirected to the court in Copenhagen.
Norway loses the steady stream of pilgrims to the relics of St. Olaf at the Nidaros shrine, and with them, much of the contact with cultural and economic life in the rest of Europe.
When things settle down, the Privy Council of Denmark has lost some of its influence, and that of Norway no longer exists.
The two kingdoms, known as Denmark–Norway, operate in a personal union under a single monarch.
Norway keeps its separate laws and some institutions, such as a royal chancellor, separate coinage and a separate army.
As an hereditary kingdom, Norway's status as separate from Denmark remains important to the royal dynasty in its struggles to win elections as kings of Denmark.
The two kingdoms will remain tied until 1814.
The Danish Reformation starts in the mid-1520s.
Some Danes want access to the Bible in their own language.
In 1524 Hans Mikkelsen and Christiern Pedersen translate the New Testament into Danish; it becomes an instant best-seller.
Tausen's version of Luther's ideas spreads throughout Denmark.
Copenhagen becomes a hotbed of reformist activity and Tausen moves there to continue his work.
His reputation precedes him and the excitement of hearing the liturgy in Danish brings thousands of people out to hear him.
With the kings' permission, churches in Copenhagen open heir doors to the Lutherans and hold services for Catholics and for Lutherans at different times of the day.
At Our Lady Church, the main church of Copenhagen, Bishop Ronnow refuses to admit the "heretics".
In December 1531 a mob storms the Church of Our Lady in Copenhagen, encouraged by Copenhagen's fiery mayor, Ambrosius Bogbinder.
They tear down statues and side-altars and destroy artwork and reliquaries.
Frederick I's policy of toleration insists that the two competing groups share churches and pulpits peacefully, but this satisfies neither Lutherans nor Catholics.
Luther's ideas spread rapidly as a consequence of a powerful combination of popular enthusiasm for church reform and a royal eagerness to secure greater wealth through the seizure of church lands and property.
In Denmark the reformation increases the crown's revenues by three hundred percent.
Many people view the tithes and fees—a constant source of irritation for farmers and merchants—as unjust.
This becomes apparent once word gets out that King Frederick and his son, Duke Christian, have no sympathy with Franciscans who persistently make the rounds of the parishes to collect food, money, and clothing in addition to the tithes.
Between 1527 and 1536 many towns petition the king to close the Franciscan houses.
Frederick obliges by sending letters authorizing the closure of the monasteries, often offering a small sum of money to help the brothers on their way.
With the royal letter in hand, mobs forcibly close Franciscan abbeys all over Denmark.
They beat up monks, two of whom die.
The closure of Franciscan houses occurs systematically in Copenhagen, Viborg, Aalborg, Randers, Malmö and ten other cities; in all, twenty-eight monasteries or houses close.
People literally hound Franciscan monks out of the towns.
No other order faces such harsh treatment.
Considering how strongly many people feel about removing all traces of Catholic traditions from Danish churches, surprisingly little violence takes place.
Luther's teaching has become so overwhelmingly popular that Danes systematically clear churches of statues, paintings, wall-hangings, reliquaries and other Catholic elements without interference.
The only exceptions come in individual churches where the local churchmen refuse to permit reform.
The State Council (Danish: Rigsråd) on Zealand, led by the Catholic bishops, takes control of the country and refuses to recognize the election of Christian III, a staunch Lutheran.
The regents fear Christian's zeal for Luther's ideas will tip the balance and disenfranchise Catholics—both peasants and nobles.
The State Council encourages Count Christopher of Oldenburg to become Regent of Denmark.
Christian III quickly raises an army to enforce his election, including mercenary troops from Germany.
Count Christopher raises an army (including troops from Mecklenburg and Oldenburg and the Hanseatic League, especially Lűbeck) to restore his Catholic uncle King Christian II (deposed in 1523).
This results in a three-year civil war called the Count's Feud (Danish: Grevens Fejde)
Rebellion sweeps across Funen, Zealand and Skåne.
Christian III's army soundly defeats an army of Catholic nobles at Svenstrup on October 16, 1534.
Christian forces a truce with the Hanseatic League, which had sent troops to help Count Christopher.
Christian III's army, under Johan Rantzau, chases the rebels all the way back to Aalborg, then massacres over two thousand of them inside the city in December 1534.
The Protestants capture Skipper Clement (1534), and later execute him in 1536.
Christian III's mercenary troops put an end to Catholic hopes on Zealand, then Funen.
Skåne rebels go as far as proclaiming Christian II king again.
King Gustav Vasa of Sweden sends two separate armies to ravage Halland and Skåne into submission.
Besiegers finally starve the last hold-outs in the rebellion, Copenhagen and Malmø, into surrender in July 1536.
By the spring of 1536 Christian III has taken firm control.
The government establishes the Danish National Church (Danish: Folkekirken) as the state church.
All of Denmark's Catholic bishops go to prison until such time as they convert to Luther's reform.
The authorities release them when they promise to marry and to support the reforms.
If they agree, they receive property and will spend the rest of their lives as wealthy landowners.
If they refuse conversion, they will die in prison.
The State confiscates Church lands to pay for the armies that had enforced Christian III's election.
Priests swear allegiance to Lutheranism or find new employment.
The new owners turn monks out of their monasteries and abbeys.
Nuns in a few places gain permission to live out their lives in nunneries, though without governmental financial support.
The Crown closes churches, abbeys, priories and cathedrals, giving their property to local nobles or selling it.
The King appoints Danish superintendents (later bishops) to oversee Lutheran orthodoxy in the church.
Denmark becomes part of a Lutheran heartland extending through Scandinavia and northern Germany.
The Catholic Church everywhere in Scandinavia has sealed its fate by supporting hopeless causes: Christian II and the emperor Charles V in Denmark, Norwegian independence in that country, and in Sweden the Kalmar Union.
Geographical distance also prevents them from receiving anything more than a sympathetic ear from Rome.
