From as early as the 13th century until 1941, Hainsfarth was home to a sometimes large Jewish community, accounting for up to 40 percent of the village's population in 1810.

In the late 16th century, this number may have fallen as low as three Jewish citizens living in the village, but it soon rose again to between seven and ten households.

Hainsfarth had a synagogue, a Jewish cemetery, a ritual bath and a religious school with a full-time teacher.

Some of them moved away or emigrated to escape the growing antisemitism but, in 1939, there were still 24 Jews in the village, reduced to eleven by 1941.

Three more Jews may still have been retained in the village until 1943 as slave labour in a local quarry, but they too were eventually deported.

After the Second World War the synagogue was confiscated by the US military and handed over to the Jewish Restitution Successor Organization (JSRO), which sold the school in 1952.

The former synagogue became a sports hall, first in the possession of the municipality of Hainsfarth, later sold to the Protestant church.

In 1836 the community started contemplating opening its own cemetery since a cholera epidemic in the region led to a temporary ban on transporting corpses.
