Chaim Weizmann moves to England in July 1904 to pursue his chemistry studies.
He also lobbies influential British citizens and politicians about Zionism, including Arthur Balfour and David Lloyd George.
When war breaks out in 1914, Weizmann redoubles his efforts, convinced that an Allied victory will help the Zionist cause.
In 1917 those efforts bear fruit when England issues the Balfour Declaration, a statement of support for a Jewish National Home in Palestine.
