The thirteen colonies that will become the United States of America have all been established by 1732 with the British colonization of Georgia.

All have local governments with elections open to most free men, with a growing devotion to the ancient rights of Englishmen and a sense of self-government stimulating support for republicanism.

With extremely high birth rates, low death rates, and steady settlement, the colonial population grows rapidly as relatively small native populations are eclipsed.

Northeastern North America

(1732 to 1743 CE): Territorial Expansion, Indigenous Diplomacy, and Economic Consolidation

Between 1732 and 1743, Northeastern North America saw territorial growth, intensified colonial rivalries, significant indigenous diplomacy, and economic prosperity through plantation agriculture and maritime commerce. This era also witnessed a powerful wave of religious revivalism known as the Great Awakening, and expansive French exploration into North America’s interior river valleys, significantly shaping cultural, social, and geopolitical dynamics.

Establishment and Expansion of British Colonies

Founding of Georgia (1732–1733)

In 1732, Britain founded its last mainland colony, Georgia, under James Oglethorpe. Designed as a refuge for debtors and as a buffer against Spanish Florida and French Louisiana, Georgia’s principal settlement, Savannah, emerged rapidly in 1733. Despite initial prohibitions against slavery and large plantations, regional economic pressures soon eroded these early ideals.

Economic Flourishing of South Carolina

South Carolina’s economy continued thriving, particularly due to rice plantations and extensive reliance on enslaved African labor. By the 1730s, Charleston ranked among the wealthiest colonial ports, exporting rice, indigo, deerskins, lumber, and beef, cementing South Carolina’s position as a dominant southern colony.

Louisbourg’s Strategic Importance

Completion and Prosperity of Louisbourg

By the early 1730s, France completed construction of the fortress town Louisbourg on Cape Breton Island. Louisbourg quickly became the most formidable French fortress in North America, strategically protecting maritime routes to New France and guarding vital fishing grounds on the Grand Banks. Its vibrant economy connected France, New France, and the French Caribbean colonies, escalating Anglo-French rivalries.

French Exploration into the Interior

Expansion of French Voyagers and Trade Routes

During this era, French voyageurs significantly expanded exploration into North America's interior. By 1743, French expeditions had explored and mapped extensive new regions, including the river valleys of the Red, Arkansas, and Platte Rivers, as well as areas surrounding Lake Winnipeg, Lake Manitoba, and along the Lower Saskatchewan River. This expansion deepened French influence, extending their trade networks and alliances far into the continental interior, establishing essential fur-trade pathways that would shape future geopolitical conflicts.

The Great Awakening and Religious Revivalism

Religious Enthusiasm and Growing Pluralism

The Great Awakening, a powerful Christian revivalist movement that peaked in the 1730s and 1740s, profoundly influenced colonial culture and society. Preachers such as Jonathan Edwards and later George Whitefield inspired widespread evangelical enthusiasm, leading to increased church participation, religious diversity, and a growing insistence on religious liberty. This movement fostered the growth of new denominations, weakened established religious authorities, and laid foundational ideas about individual rights and liberties that would later influence colonial politics.

Indigenous Diplomacy and Realignments

Plains and Great Lakes Indigenous Nations

On the Plains, the Cheyenne solidified relationships with the semi-sedentary agricultural communities of the Mandan, Hidatsa ("Tsé-heše'émâheónese"), and the Arikara ("Ónoneo'o"). Adopting agricultural practices and adapting to Plains life, they strengthened their resilience against external pressures.

The agriculturally sophisticated Mandan and Hidatsa maintained fortified villages along the Missouri River, thriving through trade, while the Arikara continued to hold vital roles as regional economic intermediaries.

French and British Rivalries in the Interior

Strengthening French-Miami Relations

French commanders such as Jean Baptiste Bissot, Sieur de Vincennes, maintained strategic alliances with the Miami at Kekionga (present-day Fort Wayne, Indiana). French traders leveraged these alliances, expanding trade routes and fortifying economic and political influence throughout the Ohio Valley and Illinois Country.

British Frontier Pressures and Indigenous Diplomacy

Britain continued westward settlement pressures from Pennsylvania, Virginia, and the Carolinas, increasing competition with French and indigenous interests. Indigenous nations, notably the Haudenosaunee (Iroquois Confederacy), engaged in sophisticated diplomacy, carefully managing European rivalry through strategic neutrality and selective alliances.

Maritime Commerce, Piracy, and Urban Growth

Prosperity and Regulation in New York City

New York City expanded rapidly during the 1730s, significantly engaged in Atlantic maritime commerce and the slave trade. British regulatory efforts intensified to curb piracy, but the city continued its economic ascent, reinforcing its critical role in colonial trade networks.

Slavery, Social Stratification, and Economic Dependence

Deepening Dependence on Enslaved African Labor

The prosperity of South Carolina’s plantation economy deepened reliance on enslaved Africans, reinforcing rigid social stratification based on race. Georgia’s initial resistance to slavery gradually weakened under economic pressure from its neighbors, laying the groundwork for slavery’s eventual establishment there.

Spanish Persistence and the Florida Frontier

Oglethorpe’s Georgia and Spanish Tensions

Spanish settlements, notably St. Augustine, remained resilient despite increased British frontier pressure. In 1740, James Oglethorpe unsuccessfully attempted to capture St. Augustine, highlighting ongoing Anglo-Spanish tensions and solidifying the southern colonial border.

Environmental Transformations and Agricultural Innovations

African Agricultural Techniques in Rice Cultivation

South Carolina’s plantation agriculture extensively utilized enslaved Africans’ agricultural knowledge, particularly in rice cultivation. Complex irrigation and water-management systems, including dikes and canals, transformed the Lowcountry ecology, ensuring large-scale, profitable rice production.

Legacy of the Era (1732–1743 CE)

The era from 1732 to 1743 profoundly influenced Northeastern North America. The establishment of Georgia completed British territorial claims along the Atlantic seaboard, intensifying rivalries with Spanish Florida and French Louisiana. Louisbourg’s strategic completion and expanded French explorations inland deepened Anglo-French tensions, setting the stage for future conflicts. The Great Awakening significantly shaped colonial culture, enhancing religious pluralism and ideas about individual liberty. Indigenous nations continued strategic adaptations, maintaining autonomy amid competing colonial pressures. Economic prosperity driven by plantation agriculture, slavery, and maritime trade reinforced regional wealth and social stratification. Collectively, these developments laid critical foundations for economic growth, indigenous diplomacy, geopolitical rivalry, and cultural transformations shaping subsequent North American history.

The Great Awakening, as the Christian revivalist movement of the 1730s and 1740s is known, fuels interest in both religion and religious liberty.

Northeastern North America

(1744 to 1755 CE): Colonial Rivalries, Indigenous Transformations, and Economic Innovations

Between 1744 and 1755, Northeastern North America experienced escalating colonial conflicts, significant indigenous adaptations driven by the introduction of the horse, expanding economic innovations, and the intensifying cultural impacts of the Great Awakening. This era profoundly reshaped relationships between European powers, indigenous societies, and colonial populations, setting conditions for larger-scale confrontations such as the upcoming French and Indian War.

Colonial Conflict and Geopolitical Rivalry

King George’s War and the Siege of Louisbourg (1744–1748)

King George’s War (1744–1748), part of the broader War of the Austrian Succession, escalated Anglo-French tensions. In 1745, colonial militia, supported by the British navy, successfully captured Louisbourg, a strategically critical fortress-town on Cape Breton Island. However, the subsequent Treaty of Aix-la-Chapelle (1748) controversially returned Louisbourg to France, intensifying colonial dissatisfaction and sowing seeds of future conflict.

Expanding French Influence and Exploration

French Fortifications and the Ohio Valley

Throughout the late 1740s and early 1750s, France actively expanded its presence in the Ohio Valley, establishing forts, most notably Fort Duquesne (modern Pittsburgh) in 1754. French voyageurs explored extensive river valleys, including the Red, Arkansas, Platte, and Missouri Rivers, as well as regions around Lake Winnipeg, Lake Manitoba, and the Lower Saskatchewan River, strengthening France’s vast fur-trading networks and indigenous alliances.

The Great Awakening and Cultural Transformation

Revivalism and Religious Liberty

The Great Awakening profoundly shaped colonial culture, increasing religious diversity and promoting ideas of religious liberty. Charismatic evangelical preachers like Jonathan Edwards and George Whitefield continued driving religious fervor, significantly influencing future political thought and encouraging new denominations and cultural shifts across the colonies.

Indigenous Adaptations: Plains Tribes and Horse Culture

Adoption of the Horse on the Plains

From about 1740, the widespread adoption of horses dramatically transformed Plains societies. Tribes like the Crow, Hidatsa, Eastern Shoshone, and Northern Shoshone became skilled horse breeders and traders, maintaining relatively large herds despite harsh northern winters. These tribes' equestrian proficiency allowed them to hunt bison more effectively, altering their economies, cultures, and territorial reach significantly.

Intertribal Rivalries and Alliances

The Crow increasingly became targets for raids and horse thefts from tribes lacking large horse herds, including the powerful Blackfoot Confederacy, Gros Ventre, Assiniboine, Pawnee, and Ute. Emerging threats from the south and east, notably from the horse-rich Lakota (Sioux), Cheyenne, and Arapaho, intensified competition and conflict over valuable horse herds and hunting grounds.

Friendly relations developed between the Crow and other northern Plains tribes such as the Flathead (Salish), Nez Perce, Kutenai, Shoshone, Kiowa, and Kiowa Apache, although periodic tensions existed. Meanwhile, the formidable Iron Confederacy (Nehiyaw-Pwat), a northern Plains alliance centered on the fur trade and dominated by the Plains Cree and Assiniboine, emerged as a significant rival to the Crow. This confederation later included groups such as the Stoney, Saulteaux, Ojibwe, and Métis, shaping regional politics and economics.

Indigenous Populations and Demographic Shifts

Decline and Consolidation of Eastern Tribes

By 1750, the indigenous population along the eastern seaboard—numbering around 120,000 in the sixteenth century—had dramatically declined to fewer than 20,000 due to disease and warfare. Surviving tribes often consolidated or redefined their identities. For instance, the Mohegans merged with surviving Pequot peoples, and the Mahicans became known as the Stockbridge Indians after relocating to Stockbridge, Massachusetts.

Migration of the Tuscarora

Following their defeat in the Tuscarora War (1711–1713) against Carolina colonists, the Tuscarora migrated northward. By the mid-eighteenth century, they had joined the Iroquois Confederacy, becoming its sixth nation, a significant adaptation reshaping Iroquois political and social structures.

British Colonies: Economic Prosperity and Social Change

South Carolina’s Wealth and Cultural Expansion

South Carolina’s economy thrived due to rice cultivation and maritime trade, significantly dependent on enslaved African labor. By mid-century, Charleston was a leading colonial port, exporting rice, indigo, naval stores, and lumber. Prosperity fueled significant cultural growth, exemplified by institutions like the Charleston Library Society (founded 1748) and by the first theater building in America, erected in Charleston in 1736.

Indigo Cultivation by Eliza Lucas (1747–1750)

In 1747, Eliza Lucas introduced and perfected indigo cultivation in the Lowcountry with critical knowledge from enslaved Africans from the Caribbean. Supported by British subsidies, indigo quickly became a leading export by 1750, greatly enriching South Carolina’s economy.

Colonial Frontier Tensions

Virginia and the Ohio Valley Conflict

Virginia’s expanding colonial claims conflicted directly with French ambitions in the Ohio Valley. Virginia asserted territorial rights based on treaties with the Iroquois Confederacy and royal charters, while France insisted on the region’s inclusion within Louisiana. This dispute heightened frontier tensions, ultimately leading to confrontations that foreshadowed the upcoming French and Indian War.

Frontier Tensions with Spanish Florida

Continued Anglo-Spanish Rivalries

The earlier unsuccessful siege of St. Augustine (1740) by James Oglethorpe left lingering distrust and frequent minor conflicts along the Georgia-Florida border. These continued hostilities underscored broader British-Spanish rivalry in the southeastern colonies.

Environmental Transformations and Agricultural Innovations

African Agricultural Techniques and Landscape Change

Enslaved Africans further refined sophisticated irrigation and water-management techniques central to rice cultivation in South Carolina’s Lowcountry. These innovations significantly reshaped regional landscapes, ensuring increased agricultural productivity, which underpinned the colony’s wealth and prominence.

Legacy of the Era (1744–1755 CE)

The years 1744 to 1755 marked significant geopolitical, cultural, and economic shifts in Northeastern North America. Colonial rivalries escalated with the return of Louisbourg to France, intensifying Anglo-French hostilities. French territorial ambitions, notably in the Ohio Valley, significantly raised tensions with Britain and its colonies, setting the stage for broader future conflicts. The Great Awakening fundamentally reshaped colonial religious, social, and political thought. Indigenous societies rapidly adapted, especially on the Plains, where the widespread adoption of horses transformed economies, societies, and intertribal relations. The severe population decline and tribal consolidations among eastern indigenous groups permanently altered regional demographics. South Carolina’s economic expansion, driven by enslaved labor, indigo cultivation, and maritime trade, solidified economic and social hierarchies, while Virginia’s contested claims in the Ohio Valley intensified colonial rivalries. These intertwined developments established essential conditions for the impending French and Indian War, dramatically reshaping North America’s future.
