Estonia had been completely subjugated by the Northern Crusaders from Germany and Denmark with the conquest of Ösel (Saaremaa) by the Livonian Order in 1261.
The new rulers had imposed taxes and duties even as the indigenous population retained individual rights, such as the right to bear arms.
Oppression had hardened as the new ruling class started to build manor-houses all over the country.
The weight of duties to the lay masters is redoubled by religious repression and economic demands imposed by the church.
The area is also politically unstable.
The Estonian provinces of Harria (Harju) and Vironia (Viru) had been conquered by Denmark but by the fourteenth century the kingdom's power has weakened.
The province in Estonia has become split between a pro-Danish party led by bishop Olaf of Reval and the pro-German party led by captain Marquard Breide.
Eighty percent of the Danish vassals in the Duchy of Estonia are Germans from Westphalia, eighteen percent are Danes and two percent Estonians.
The Estonian peasantry, despite guarantees of certain rights and freedoms under peace treaties with the Danish and German nobles (who have, four six score years, held much land in Estonia as fiefs), suffer abuse from their feudal overlords and respond with sporadic violence against them.
A major revolt had broken out on April 23, 1343,Saint George’s Day.
Beginning in Harjumaa county, the rebellion has spread to surrounding areas, including the island of Oesel.
The rebellious peasants kill more than eighteen hundred nobles, who lay siege to Tallin and request help from Swedish forts in Finland.
The Teutonic Knights, responding to the beleaguered nobles’ call for support, enter the fray, arrange a peace conference, and murder the rebel peasant leaders at the meeting.
The Knights then battle the peasant rebels near Tallinn, routing them before Swedish help can arrive.
