The event in 1948 that resulted in the establishment of Israel as a nation-state was the declaration of independence by David Ben-Gurion on May 14. After decades of increasing Jewish migration to Palestine and the aftermath of the Holocaust, the United Nations proposed a partition plan to create separate Jewish and Arab states. The Jewish community accepted this plan, leading to the formation of the State of Israel. However, this declaration sparked immediate conflicts, as neighboring Arab countries opposed the establishment of Israel, resulting in the Arab-Israeli War of 1948, which intensified regional tensions.
