Who sided with the Palestinians in trying to keep the Jewish people out?

Historically, various Arab nations and groups have sided with the Palestinians in efforts to prevent the establishment of a Jewish state in Palestine. This opposition intensified during the early 20th century, particularly around the time of the 1947 United Nations Partition Plan and the subsequent 1948 Arab-Israeli War. Countries such as Egypt, Jordan, Syria, and Iraq played significant roles in opposing Jewish Immigration and the establishment of Israel. Additionally, organizations like the Arab League were formed to support the Palestinian cause and resist the creation of Israel.
