World Union for Progressive Judaism  The World Union for Progressive Judaism (WUPJ) is the international umbrella organization for the various branches of Reform, Liberal and Progressive Judaism, as well as the separate Reconstructionist Judaism. The WUPJ is based in 40 countries with 1,275 affiliated synagogues, of which 1,170 are Reform, Progressive or Liberal and 105 Reconstructionist. It claims to represent a total of some 1.8 million people, both registered constituents and non-member identifiers. The WUPJ states that it aims to create common ground between its constituents and to promote Progressive Judaism in places where individuals and groups are seeking authentic, yet modern ways of expressing themselves as Jews. It seeks to preserve Jewish integrity wherever Jews live, to encourage integration without assimilation, to deal with modernity while preserving the Jewish experience and to strive for equal rights and social justice. The WUPJ was established in London in 1926 as the Union of all Progressive (also Liberal or Reform) movements. It moved its headquarters to New York in 1959 and to Jerusalem in 1973. In 1990, the Reconstructionists – who espouse a philosophy different from that of the former – joined the WUPJ under an observer status, being the first and only non-Reform member. The WUPJ has regional offices in London, Moscow and New York City. As of September 2014 the President of the WUPJ is Rabbi Daniel H. Freelander, and the Chair is Carole Sterling. Past presidents included Claude Montefiore (1926-1938)), Rabbi Leo Baeck (1938-1956), Lily Montagu (1955–1959), and Rabbi Solomon Freehof (1959-1964). The URJ is by far the largest member organization of the WUPJ, with a solid constituency of over 750,000 Jewish members (along with further 90,000 unconverted gentile spouses) and over a million non-members who identify with it in the U.S., and further 30,000 constituents in Canada. As of 2016, 1.5 million of the 1.9 million members of WUPJ are in the U.S. German immigrants and rabbis brought Reform to America, although a short-lived congregation that espoused a somewhat similar ideal existed in Charleston between 1824 and 1833. The Union of American Hebrew Congregations, URJ since 2003, was founded in 1873. North America is also home to the Jewish Reconstructionist Federation, which has affiliates, 97 only Five of them outside the continent (in Delft, Netherlands Curaçao Weisbaden, Germany Serrastretta, Italy Moscow, Russia).
