10 Zlotys University of Warsaw

Issued to mark the 200th anniversary of the University of Warsaw, founded in 1816 under the Kingdom of Poland — a Russian-controlled constitutional monarchy established by the Congress of Vienna the previous year. The university's early decades were turbulent: it was closed by Tsar Nicholas I following the November Uprising of 1830, did not reopen in any meaningful form until the 1860s, and was then shuttered again after the January Uprising of 1863, remaining closed until 1915.

Nazi occupation brought a second forced closure in 1939, during which faculty and students continued clandestine teaching under threat of death.
