A photograph of a meeting held in London on 2 December 1917 to express thanks to the British government for the Balfour Declaration. The Balfour Declaration was in fact a letter, written a month earlier on 2 November, from the Foreign Secretary, Arthur Balfour, to Lord Rothschild. The letter said that the British government viewed 'with favour the establishment in Palestine of a national home for the Jewish people' and became very important in helping to gain international support to set up what is now the modern state of Israel.
