Shlomo Yosef Burg (Hebrew: שלמה יוסף בורג, 31 January 1909 - 15 October 1999) was an Israeli politician. In 1949, he was elected to the first Knesset, and served in many ministerial positions for the next 40 years. He was one of the founders of the National Religious Party.
While studying at the University of Leipzig, he joined the Young Mizrahi religious Zionist movement. He arranged Jewish prayer services in private homes after German synagogues were burned, and worked underground to help Jews escape to Britain and the Netherlands. His mother and grandmother died in Nazi concentration camps.
In 1956 Hapoel HaMizrachi merged with their ideological twins from the Mizrachi party to form the National Religious Party (NRP). The party was a member of all governments until 1992. In 1977, he became the president of the World Mizrachi Movement. As a key party member, Burg maintained a ministerial position in every Knesset until his resignation from the Knesset and retirement from politics in 1986, holding the positions of minister of welfare, minister of internal affairs, minister without portfolio and minister of religious affairs.
Burg was famous for his erudite wit. Journalists dubbed his appearances in parliament "Burgtheater," after the famous playhouse in Vienna.
According to Shimon Peres, Burg's most important legacy was trying to bridge the gulf between religious and secular Jews: "He was a religious man but he believed in compromise."Ehud Barak said Burg took the path of moderation and tolerance, and showed a love for Jewish tradition.
