In the mid-eighteenth century, Roman Catholics constituted 53,7% of the population, members of the Greek Catholic Church 23,9%, and Jews 22,3%.
Jarosław was under Austrian rule from the First Partition of Poland in 1772 until Poland regained independence in 1918. After the Second World War the city remained part of Poland. Poland's communist government expelled most of Jarosław's Ukrainian population, at first to Soviet territories and later to territories transferred from Germany to Poland in 1944-45.
The first Jews reportedly arrived in Jarosław in 1464. The first rabbi of Jarosław was Rabbi Nathan Neta Ashkenazi, in 1590. A year later, the new Council of Four Lands (Vaad Arba Aratzot) began convening in Jarosław, rotating the meeting with the city of Lwów (Lviv).
Until 1608 with a small Jewish community, religious facilities were not allowed. Still, Rabbi Solomon Efraim of Lontschitz (the author of "Kli Yakar"), a prominent and well known rabbi, lived here. By 1670 there was a large "government" synagogue created, although protested by the Christian community of the city. During attacks on the city by Tatars and Swedes, Jewish merchandise and sometimes homes were set on fire. In 1765, there were 1,884 Jews in the city and towns around it. A Jewish school was established sometime later. The famous rabbi Levi Isaac of Berdyczów (Berdychiv) studied in Jarosław circa 1760 and was called "the genius of Yeruslav". A fire in 1805 burnt down the old synagogue and a new one was established more according to tradition to replace it. The new synagogue was completed in 1811. A census taken in 1901 notes that Jews were 25% of the population: 5701 Jewish families.
In a story about Jacob Kranc told by Rabbi Jacob Orenstein around 1850, about the appointment of the Jarosław rabbi, Rabbi Orenstein had refused the appointment of Rabbi of Jarosław because it would be against his old uncle's appointment. The city council had already written his appointment and wished to express their sorrow for its cancellation. The Dubner Magid had just entered the city on a snowy winter day, and was taken directly to Orenstein's house, together with the city council, who happened to pass by him. But the walk up the steps was sufficient enough to create a moving speech, remembered years later, and accounted for in the book.
In 1921 the last rabbi was appointed, Rabbi Shmaiya HaLevi Steinberg. He wrote a book about the Jews of his town, and in the 1930s sent two copies to the National Hebrew Library in Jerusalem. These copies are the only surviving copies of the book after the Holocaust.
In September 1939, Jarosław was captured by Germans. Most of the Jews crossed the San river to the Soviet side and hid in the Ural mountains, including the elder rabbi and his family. Those that stayed were shot and killed by the German soldiers.
