Write a 3-4 sentence description of the Balfour declaration.

The Balfour Declaration was a public statement issued by the British government on November 2, 1917, expressing support for the establishment of a "national home for the Jewish people" in Palestine. Authored by Foreign Secretary Arthur James Balfour, the declaration was a significant milestone in the international recognition of Zionism and paved the way for the eventual establishment of the State of Israel. However, the declaration has also been criticized for its role in the displacement of Palestinian Arabs and the ongoing conflict in the region.
