Before statehood he headed the Jewish Agency's political department from 1933, and during the Second World War he founded the Jewish Brigade, which fought alongside the British Army against Nazi Germany. He later negotiated the armistice agreements that ended the 1948 war, working the diplomatic side of Israel's founding while David Ben-Gurion held its political leadership on either side of him.
