The settlement was established in 1770 by former Saxon and Polish official of Danish origin and then commander-in-chief of the Russian army in Moldavia and Wallachia, Baron Piotr Mikołaj Gartenberg Sadogórski [de], and named Sadogóra after him.

On his release he fled to Chișinău, then to Iaşi and other places before finally settling in Sadagóra in 1842, where he re-established his Hasidic court in all its glory.

The Ruzhiner Rebbe lived in Sadagóra for ten years, building a palatial home and a large synagogue.

His eldest son,[7] Rabbi Sholom Yosef Friedman, remained in Sadagóra to continue leading the court his father had founded, but died ten months later.

He, in turn, was succeeded by his eldest son, Rabbi Aharon of Sadigura (1877-1913), and by another son, Rabbi Avrohom Yaakov Friedman, who escaped to Vienna with the outbreak of World War I in 1914 and established his court in that city for the next 24 years,[4][9] effectively putting an end to the once-flourishing Jewish community in Sadagóra .
