[4] During the Revolution of 1905, Ożarów was part of the so-called Ostrowiec Republic (Republika Ostrowiecka), anti-Russian revolutionary movement, led by the Polish Socialist Party.

In 1915, the village was visited by Józef Piłsudski, and in late May of that year, a skirmish between Polish Legions in World War I and the Russian Imperial Army took place here.

During occupation of Poland in World War II, the Nazi Germans created a Jewish ghetto in Ożarów for the imprisonment not only of the local Jews but also deportation transports from Radom, Włocławek and even from Vienna.

The ghetto held around 4,500 inmates between January and October 1942, at which time all inhabitants were loaded onto Holocaust trains, shipped to Treblinka extermination camp and murdered upon arrival.

The population quickly grew in the late 1970s and early 1980s, and on December 18, 1987, the government of the People's Republic of Poland agreed to grant town charter to the village.
