The new name of these three combined villages was Trzciana Łąka, as it appeared for the first time in 1565, and it was subsequently changed to Trzcianka in the 17th century.

[2] In 1671 Polish King Michał Korybut Wiśniowiecki issued a privilege which established new annual fairs in Trzcianka.

In the final months of World War II, Soviet troops marching towards Berlin from the east entered the town on 27 January 1945.

In August 1980, employees of local factories joined the nationwide anti-communist strikes,[5] which led to the foundation of the "Solidarity" organization.
