[4] During World War II, Siret was captured on 3 April 1944 by Soviet troops of the 1st Ukrainian Front in the course of the Dnieper–Carpathian Offensive.

Given the 14th century decline of the Byzantine empire as Orthodox regional superpower-ally and Latin mendicant orders missions since the 13th century, the prince Bogdan I of Moldavia obtained virtual independence in 1359 as founding voivode (autonomous prince), seeking aid and protection from Poland, welcomed Latin missionaries, Francescans (founding a monastery at Siret in 1340) and Dominicans.

His son and indirect successor Lațcu of Moldavia (1365-1373) promised Rome his and the people's conversion to Catholicism and asked Pope Urban V to send missionaries and erect a Latin diocese in his principality's capital, Siret, which happened in 1371, initially directly subject to the Holy See until 1412 when it was made suffragan of the Archbishopric of Lviv (Lwów in Polish; now in Ukraine).

This Roman Catholic Diocese of Siret started to decline in 1388 when prince Petru of Moldavia transferred the Moldavian voivode's capital from Siret to Suceava, and was effectively suppressed, but from circa 1418, the Holy See erected another Moldavian bishopric, the Diocese of Baia, which inherited its territory (c. 1434).

Zionist activity began at the turn of the 20th century, a time when most of the local Jews worked in commerce.

During World War I, Jews fled in advance of the Imperial Russian Army, and found their property destroyed when they returned.

This active program began in 1991, and regular events, such as a produce market from each of the other countries[clarification needed] and festivals.
