Osieczna

Following the successful Greater Poland uprising of 1806, it was included within the short-lived Polish Duchy of Warsaw.

After the duchy's dissolution in 1815, it was reannexed by Prussia, and from 1871 it was also part of Germany.

On January 11, 1919, Osieczna was the site of a victorious battle of the Polish insurgents against the Germans during the Greater Poland uprising,[4] and it was soon reintegrated with Poland, which just regained independence.

During the German occupation of Poland (World War II), on October 21, 1939, the Germans carried out a public execution of a group of local Poles (see Nazi crimes against the Polish nation).

[5] It was one of many massacres of Poles committed by Germany on October 20–23 across the region in attempt to pacify and terrorize the Polish population.
