East Prussia in German Empire
Location of East Prussia in the German Empire (1878)

East Prussia genealogy relates to the study of family history research in the former province of the Kingdom of Prussia, known as Ostpreußen in German. The territory existed from 1773 through 1829, and then again from 1878 until 1945 as part of the German Empire. In between 1829 and 1878, it united with West Prussia to form the province of Prussia.

The old territory of East Prussia now lies within the modern borders of Poland and Russia.

In the early 19th century, it was made up of about half ethnic Germans, a quarter ethnic Polish[1], and the remainder of residents were mostly Curonian, Latvian or Jewish. Religiously, its population was primarily Evangelical Christian with a small percentage of Roman Catholics and even smaller populations of Mennonites and Jews.[2]

History of East Prussia

Friedrich I, leader of the Kingdom of Prussia
Friedrich I of the Kingdom of Prussia, who reigned as King from 1701 to 1713.

Prior to the 1300s, a Slavic people lived around the Baltic; they were called Preussen and they were kin with the Lithuanians and Latvians.[3] They were forced to convert to Christianity by the Teutonic Knights, a religious order that originated in the Middle East.[4] German peasants came to farm the land and by the mid-14th century, the majority of the population was German.[3] The land became part of the Kingdom of Poland from 1466 to 1701.[5]

The Kingdom of Prussia was founded on Jan. 18, 1701, when a son of Elector of Brandenburg Friedrich Wilhelm crowned himself as Friedrich I, King of Prussia.[3] The ceremony took place in Königsberg (modern-day Kaliningrad, Russia), which became the capital city of East Prussia. His son and successor, Friedrich Wilhelm I, born in Berlin in 1688, turned Prussia into a military power known for its discipline and speed.[6]

Prussia became involved with several military conflicts, most notably:

At the conclusion of World War II, the northern part of East Prussia was annexed by the Soviet Union, while the remainder went to Poland or was divided into zones of occupation by the victorious allies.[7]
