The Board of Guardians for the Relief of the Jewish Poor or, as it is most generally known, the Jewish Board of Guardians, was a charity established by the upper class Jewish community in the East End of London in 1859. The Board sought to provide relief for Jewish immigrants and soon became the central provider of relief for the Jewish poor in London. After an amalgamation with other charities in the 1990s, the Jewish Board of Guardians became Jewish Care, an organization that still exists today.
