The Period of the Divided Kingdoms of North and South and the Period of the Divided Kingdoms of East and West
The United Kingdom, which had begun with King Saul, was carried on through King David and King Solomon; then it divided into the ten tribes of the Northern Kingdom of Israel, which was in Cain's position, and the two tribes of the Southern Kingdom of Judah, which was in Abel's position. Thus, the period of the divided kingdoms of North and South came about.
Likewise, the Christian Kingdom, which had began with Charlemagne, divided into three parts-the East Franks, the West Franks and Italy-due to quarrels between his three grand sons. However, since Italy was under the rule of the East Franks, it was actually a period of division into the Kingdoms of East and West.
