The Kingdom of Judah was an Israelite kingdom of the Southern Levant during the Iron Age. Centered in the highlands to the west of the Dead Sea, the kingdom's capital was Jerusalem. It was ruled by the Davidic line for four centuries. Jews are named after Judah, and primarily descend from people who lived in the region.
The Hebrew Bible depicts the Kingdom of Judah as one of the two successor states of the United Kingdom of Israel, a term denoting the united monarchy under biblical kings Saul, David, and Solomon and covering the territory of Judah and Israel. However, during the 1980s, some biblical scholars began to argue that the archaeological evidence for an extensive kingdom before the late 8th century BCE is too weak, and that the methodology used to obtain the evidence is flawed. In the 10th and early 9th centuries BCE, the territory of Judah might have been limitedly populated, comprising some fortified sites and many unfortified rural settlements. The Tel Dan Stele, discovered in 1993, shows that the kingdom existed in some form by the middle of the 9th century BCE, but it does not indicate the extent of its power. Recent excavations at Khirbet Qeiyafa, however, support the existence of a centrally organized and urbanized kingdom by the 10th century BCE, according to the excavators.
