The Board of Deputies of British Jews, commonly referred to as the Board of Deputies, is the largest and second oldest Jewish communal organisation in the United Kingdom, after the Initiation Society which was founded in 1745. Established in 1760 by a group of Sephardic Jews, the board presents itself as a forum for the views of most organisations within the British Jewish community, liaising with the British government on that basis. Notably, while Lord Rothschild was President of the Board of Deputies, the Balfour Declaration was addressed to him and eventually led to the creation of a Jewish state in Palestine. It is affiliated to the World Jewish Congress and the European Jewish Congress. The current president is Marie van der Zyl. She will be succeeded by Phil Rosenberg in July 2024.

Sir Moses Haim Montefiore, 1st Baronet, was a British financier and banker, activist, philanthropist and Sheriff of London. Born to an Italian Sephardic Jewish family based in London, after he achieved success, he donated large sums of money to promote industry, business, economic development, education and health among the Jewish community in the Levant. He founded Mishkenot Sha'ananim in 1860, the first Jewish settlement outside the Old City of Jerusalem.
