The Zionist Organization of America (ZOA) () is an American non-profit pro-Israel organization. Founded in 1897, as the Federation of American Zionists, it was the first official Zionist organization in the United States. Early in the 20th century, it was the primary representative of American Jews to the World Zionist Organization, espousing primarily Political Zionism. Today, the ZOA claims to have 25,000 members, down from its 1939 peak of 165,000. The ZOA opposes Palestinian statehood and advocated for the Trump travel ban. History Founding The ZOA was initially founded in 1897 as the Federation of American Zionists (FAZ), an amalgam of Hebrew societies, Chovevei Zion, and Jewish nationalist clubs that all endorsed the Basle programme of the First Zionist Congress. Initially founded as an organization for the greater New York area, the FAZ was established as a national organization at a conference in New York the next year where the constitution was adopted by the delegates with Richard Gottheil elected as president and Stephen S. Wise as honorary secretary. The FAZ was meant to support the founding of the 'Jewish National Home in Palestine'. Along with its sister organization, Hadassah Women's Zionist Organization of America, founded 1912, as well as the Labor Zionist Po'ale Zion parties, and the Religious Zionist Mizrachi, the ZOA served as one of the key voices in early American Zionism. Their voice was limited however, since most American Jews and the organized American Jewish Committee were initially strong opponents of the Zionist movement, and worried, with their assimilationist views, about charges of 'dual loyalty', a common antisemitic canard. In 1917, the FAZ was renamed as the ZOA. Louis Brandeis and subsequent history When the secular "people's lawyer" Louis Brandeis became involved in the movement in 1912, just before World War I, Zionism started gaining significant support. By 1917, Brandeis' leadership had increased American Zionist membership ten times to 200,000 members, and "American Jewry thenceforth became the financial center for the world Zionist movement," greatly surpassing its previous European base of support. In addition, during the early years of World War I, he and others established the American Provisional Executive Committee for General Zionist Affairs to run Zionist affairs on behalf of the worldwide Zionist Organization, which had been rendered largely impotent because its members were divided by allegiance to the different sides in the conflict. In 1949, the Federal Bureau of Investigation investigated the ZOA under
