what caused the split between israel and judah
Kingdom of Israel (united monarchy) Following Solomon's death in c. 926 BCE, tensions between the northern part of Israel containing the ten northern tribes, and the southern section dominated by Jerusalem and the southern tribes reached boiling point. When Solomon's successor Rehoboam dealt tactlessly with economic complaints of the northern tribes, in about 930 BCE (there are differences of opinion as to the actual year) the United Kingdom of Israel and Judah split into two kingdoms: the northern Kingdom of Israel, which included the cities of Shechem and Samaria, and the southern Kingdom of Judah, which contained Jerusalem; with most of the non-Israelite provinces achieving independence.
History of the Israeli–Palestinian conflict This conflict came from the intercommunal violence in Mandatory Palestine between Israelis and Arabs from 1920 and erupted into full-scale hostilities in the 1947–48 civil war. The conflict continues to the present day on various levels.
