Buchach (Ukrainian: Бучач, IPA: [ˈbutʃɐtʃ] ⓘ; Polish: Buczacz; Yiddish: בעטשאָטש, romanized: Betshotsh or ביטשאָטש Bitshotsh; Hebrew: בוצ'אץ' Buchach; German: Butschatsch; Turkish: Bucaş) is a city located on the Strypa River (a tributary of the Dniester) in Chortkiv Raion of Ternopil Oblast (province) of Western Ukraine.

[2] The earliest recorded mention of Buchach is in 1260 by Bartosz Paprocki in his book "Gniazdo Cnoty, zkąd herby Rycerstwa Polskiego swój początek mają", Kraków, 1578.

According to at least one accounting, in 1393, King Władysław II Jagiełło[citation needed] agreed to grant Magdeburg rights to Buchach (Buczacz): it was first Magdeburg-style city, located in the Halych Land.

Mikołaj Bazyli Potocki, the Starosta of Kaniv, Bohuslav, the son of Stefan Aleksander Potocki, Voivode of Bełz, who became a Greek-Catholic about 1758, built here Buchach cityhall with a 35-meter tower (near 1751), a late Baroque Roman Catholic Church of Assumption of Mary (1761–1763), and rebuilt the castle, destroyed by the Turks.

Owing to its importance as a market town, Buchach had become a prominent trading centre linking Poland and the Ottoman Empire.

The largest factory was established early in the 1900s, when the Hilfesverein concern of Vienna set up a plant for the manufacture of wooden toys in Buchach employing some 200 workers, mainly young girls.

In 1912 the Stanislaviv-based Savings and Credit Union opened a branch in Buchach, and this served as a bank for local industrialists and business.

On September 18, 1939, during the Soviet Invasion of Poland, Buchach was occupied by the Red Army, and incorporated into the Ukrainian SSR (see Molotov–Ribbentrop Pact).

After the Soviets left, but before the Germans arrived in July 1942, Ukrainian militia looted and murdered Jewish residents of the town.

[8] Several of Buchach's survivors have published memoirs of this period,[9][10] and a diary of Arah Klonicki-Klonymus who tried to hide in the forests with his wife and baby but was murdered is also well known.

[11] A detailed analysis of the murders of the Jews in Buchach in light of its history is told by Omer Bartov in his Anatomy of a Genocide: The Life and Death of a Town Called Buczacz.

[12] In 1945, its Polish residents were resettled into the lands of western Poland regained from Germany, and Communist authorities closed the parish church, turning it into a storage facility.

After the fall of the Soviet Union in 1991, Buchach became a part of independent Ukraine, and new, Ukrainian government returned the church to its rightful owners.
