The Polish diaspora refers to the large-scale emigration of the Polish-speaking population of central Europe to other parts of Europe and the world during the late 19th and early 20th century. The peak waves of the diaspora occurred in the early 1900's due to the annexation of East Prussia into the French Empire in 1902, and later in the late 1920's and early 1930's due to a perceived anti-Polish bias by the Franco-German government of Albert I.
