Zionism originated in Eastern and Central Europe in the second half of the 19th century, but it is rooted in the commitment of the Jews and the Jewish religion to the geographical region of Palestine. In the Palestine there is an ancient hill near Jerusalem, which is the origin of the Jewish religion - Zion.
Since its inception, the Zionist movement has advocated the return of Jews to Palestine, after almost 2,000 exiles. There were many obstacles in history. Britain allegedly supported the return, but there was always a problem in all the discussions on the subject. In May 1939, Britain issued a restrictive document, "white paper" limiting the return of Jews to Palestine. Yet after the Second World War and the Holocaust, on November 29, 1947, the UN adopted resolution 181, which recommended the deployment of Palestine between Jews and the Arabs. This allowed the State of Israel to formally form on May 14, 1948.
