Romania is a country rich in Jewish heritage. The first Jews arrived as part of the Roman legions (Legion Judaica) that invaded Dacia in 101 A.D. During the Middle Ages, Jewish immigrants began settling in Walachia and Moldova, with ever-increasing numbers arriving after Spain’s expulsion of the Jews in 1492. By the early 16th century, their number again increased by immigrants fleeing from Cossack uprisings in Poland and the Ukraine.
