Treaty of Kalisz
Kalisz, Greater Poland, Poland
What happened
The Kingdom of Prussia and the Russian Empire signed the alliance. After Napoleon's defeat in Russia, Prussia's General Yorck had already stopped fighting the Russians. At Kalisz, Russia and Prussia formed an alliance against Napoleon. It was written in French, even though it was aimed at France.
Why it matters
Why it matters: It marked Prussia's final switch to the side against Napoleon. Prussia declared war on France weeks later.
What came next
Yorck was cleared of blame. The allies went on to the 1813 campaign in Germany.

Kalisz calls itself 'the oldest city of Poland'.
