Until the Second World War, like many other cities in Europe, Siedlce had a significant Jewish population. At some times, indeed, Jews were the majority of its population. The presence of Jews at Siedlce is attested from the mid-16th century – inn keepers, merchants and artisans. A Jewish hospital existed in the town since the early 18th century. In 1794, a Beit Midrash (study hall) was founded in the town and 1798 the Jewish cemetery was extended, testifying to the increase of the community. These changes coincided with the town coming under Austrian rule with the Third Partition of Poland. Austrian rule lasted until 1809. It was passed to Russian rule in 1815 formally (in 1813 de facto), that lasted for over a hundred years. Until 1819 the Jewish community of Warsaw, to the west, was formally subject to the authority of the Siedlce rabbis.
