Lviv (also spelled L'viv, Lvov and Львів; Russian: Львов, Polish: Lwów, German: Lemberg) is one of the biggest cities of regional significance in Ukraine. It was a part of Poland until 1939 when it became part of Ukraine. It is currently the biggest city in the region and a major Ukrainian cultural center. The historic city center is on the UNESCO World Heritage List.
The city has a multicultural history. It was founded in 1256 by King Daniel of Galicia (the city was named after his son, Prince Leo), and it fell under Polish control in the 14th century. Poles, Jews, Ukrainians, Germans and others lived there together for centuries. The Polish king John II Casimir founded Lviv University in the 17th century and Lviv (known as Lwów) was by that time one of the most important cities in the Polish-Lithuanian Commonwealth, along with Krakow, Warsaw, Gdansk and Vilnius. In 1772 the city was taken by the Habsburgs and in Austrian times it was known under the name of Lemberg, the capital of Galicia. After the dissolution of the Austro-Hungarian Empire in 1918, it was returned to Poland. As result of World War II, Stalin moved the Soviet frontier westward so Lviv became part of the USSR, as Lvov (still widely frequent, even locally). With the Ukrainian independence in 1991, the name was officially changed to Lviv (Львів).
