included in the Western Ukrainian People's Republic. It came under Polish control in 1919 during the Polish-Ukrainian War. In April 1920, the Second Polish Republic, represented by Józef Piłsudski, and the Ukrainian People's Republic, represented by Symon Petlura signed the Treaty of Warsaw, in which they agreed that the Polish-Ukrainian border in Western Ukraine would follow the Zbruch River. This left Belz, along with the rest of Eastern Galicia in the Polish Republic. From 1919 to 1939 Belz was annexed to the Lviv Voivodeship, Second Polish Republic. From 1939 to 1944 Belz was occupied by Germany as a part of the General Government. Belz is situated on left, north waterside of the Solokiya river (affluent of the Bug river), which was the German-Soviet border in 1939–1941. After the war Belz reverted to Poland (where it was again within the Lublin Voivodeship) until 1951 when, after a border readjustment, it passed to the Soviet Union (Ukrainian Soviet Socialist Republic). (See: 1951 Polish–Soviet territorial exchange) Since 1991 it has been part of independent Ukraine. Until 18 July 2020, Belz belonged to Sokal Raion. The raion was abolished in July 2020 as part of the administrative reform of Ukraine, which reduced the number of raions of Lviv Oblast to seven. The area of Sokal Raion was merged into Chervonohrad Raion. Jewish history The Ashkenazi Jewish community in Belz was established circa 14th century. In 1665, the Jews in Belz received equal rights and duties. The town became home to a Hasidic dynasty in the early 19th century. The Rabbi of Belz, Shalom Rokeach (1779–1855), also known as the Sar Shalom, joined the Hasidic movement by studying with the Maggid of Lutzk, and established the community and become the first Belzer Rebbe, thereby establishing the Belz Hasidic dynasty. When Rebbe Shalom died in 1855, his youngest son, Rebbe Yehoshua Rokeach (1855–1894), became the next Rebbe. Belzer Hasidism grew in size during the tenure of Rebbe Yehoshua's son and successor, Rebbe Yissachar Dov Rokeach (third Belzer Rebbe)(1894–1926). Rebbe Yissachar Dov's son and successor, Rebbe Aharon Rokeach (1880 to 1957), escaped from Nazi-occupied Europe to Israel in 1944, re-establishing the Hasidut first in Tel Aviv and then in Jerusalem. For recent history see . At the beginning of World War I, Belz had 6100 inhabitants, including 3600 Jews, 1600 Ukrainians, and 900 Poles.
