when did israel divide into northern and southern kingdoms
Kingdom of Israel (united monarchy) The United Monarchy (Hebrew: המלוכה המאוחדת‬) is the name given to the Israelite[note 1] kingdom of Israel and Judah,[2][3][4] during the reigns of Saul, David and Solomon, as depicted in the Hebrew Bible. This is traditionally dated between 1050 BCE and 930 BCE. On the succession of Solomon's son, Rehoboam, around 930 BCE, the biblical account reports that the country split into two kingdoms: the Kingdom of Israel (including the cities of Shechem and Samaria) in the north and the Kingdom of Judah (containing Jerusalem) in the south.
Kingdom of Judah According to the Hebrew Bible, the kingdom of Judah resulted from the break-up of the United Kingdom of Israel (1020 to about 930 BCE) after the northern tribes refused to accept Rehoboam, the son of Solomon, as their king. At first, only the tribe of Judah remained loyal to the house of David, but soon after the tribe of Benjamin joined Judah. The two kingdoms, Judah in the south and Israel in the north, coexisted uneasily after the split until the destruction of the Kingdom of Israel by Assyria in c. 722/721.
