History of Legnica

Duke of Poland Bolesław IV the Curly funded a chapel at the St. Benedict monastery. Legnica was the most likely place of residence for Bolesław and it became the residence of the High Dukes of Poland in 1163 and was the seat of a principality ruled from 1248–1675.

Legnica became famous for the battle that took place at Legnickie Pole near the city on 9 April 1241 during the Mongol invasion of Europe. The Christian army of the Polish duke Henry II the Pious of Silesia, supported by feudal nobility, which included in addition to Poles, Bavarian miners and military orders and Czech troops, was decisively defeated by the Mongols.

After the Treaty of Versailles following World War I, Liegnitz was part of the newly created Province of Lower Silesia from 1919 to 1938, then of the Province of Silesia from 1938 to 1941, and again of the Province of Lower Silesia from 1941 to 1945.

After the defeat of Nazi Germany during World War II, Liegnitz and all of Silesia east of the Neisse was transferred to Poland following the Potsdam Conference in 1945. The German population was expelled from between 1945 and 1947 and replaced with Poles and, as the medieval Polish name Lignica was considered archaic, the town was renamed Legnica. The transfer to Poland decided at Potsdam in 1945 was officially recognized by East Germany in 1950, by West Germany under Chancellor Willy Brandt in the Treaty of Warsaw signed in 1970, and finally by the reunited Germany by the
