Mińsk Mazowiecki (Polish pronunciation: [ˈmij̃sk mazɔˈvjɛtskʲi] ⓘ "Masovian Minsk") is a town in eastern Poland with 40,999 inhabitants (2020).

During the November Uprising, it was the site of two battles between Polish insurgents and Russian troops, fought on 26 April and 14 July 1831.

The 7th Lublin Uhlan Regiment was stationed in Mińsk Mazowiecki in the interbellum, and nowadays there is a museum dedicated to the unit in the town.

On 13 September 1939, it was the site of the Battle of Mińsk Mazowiecki between Poles led by General Władysław Anders and the invading German army.

In 1939, some expelled Poles from Barcin, Kępno, Ostrzeszów, Rychtal and Szubin were deported to Mińsk Mazowiecki.

[3][4] In October 1940, the occupiers established the Mińsk Mazowiecki Ghetto, which was eventually liquidated on 21 July 1942, with most of the Jewish residents murdered at the Treblinka extermination camp in one of the first episodes of the Holocaust.

[5] On 30 July 1944, Mińsk Mazowiecki was liberated by the Polish underground Home Army (prelude to the Warsaw Uprising), however, the Soviets occupied the town the next day.

On 2–3 March 1945, the Soviets carried out executions of the local Polish elite, including Mayor Hipolit Konopka.

After the war, the town was restored to Poland, although with a Soviet-installed communist regime, which stayed in power until the Fall of Communism in the 1980s.

The Novominsk hasidic dynasty was founded here in the late 19th century by Rabbi Yaakov Perlow, a descendant of the Baal Shem Tov.
