Waterbury had a significant Jewish population beginning in the late 1800s, initially as a result of German immigration.The first synagogue in Waterbury opened in 1872 In the early 20th century, almost 9,000 Jews immigrated from Eastern Europe, with many fleeing persecution. The Orthodox Jewish community has experienced a renaissance since 2000 due to efforts by educators and developers to create an affordable alternative to the high cost of living in established Orthodox communities in New York and New Jersey. This renaissance began with the founding of the Yeshiva K'tana of Waterbury in 2000; as of 2014, this full-service elementary and middle school has nearly 400 students. Other educational institutions are the Yeshiva Gedolah of Waterbury, which includes a mesivta high school and beit medrash (undergraduate) program for approximately 230 students, a Bais Yaakov school for girls, and a kolel. As of the end of 2014, the Waterbury Orthodox community numbers 180 families and includes a mikveh, eruv, and community services such as Hatzalah and Chaverim.
