Pshevorsk is a small Hasidic movement based in Antwerp, Belgium, led by the Leiser rabbinical dynasty, originating in the Polish town of Przeworsk.

In 1956, he settled in Antwerp, where he lived until he died on Yom Kippur in 1976 (year 5737 in the Hebrew calendar).

Yaakov Leiser is buried in Putte, Netherlands, because a Belgian law makes it possible to re-use or build on top of gravesites.

There is a shul in Jerusalem too, which was led by the Rebbe's son Shulem, until he left religion and became off the derech.

The current Rebbe continues the close ties with Satmar and agrees with their anti-Zionist views.
