By the late Bronze Age, a historically recorded people and land (Midian and the Midianites) in the north-western portion of Saudi Arabia are well-documented in the Bible. Centred in Tabouk, it stretched from Wadi Arabah in the north to the area of al-Wejh in the south. The capital of Midian was Qurayyah, it consists of a large fortified citadel encompassing 35 hectares and below it lies a walled settlement of 15 hectares. The city hosted as many as 10 to 12 thousand inhabitants. The Midianites were depicted in two major events in the Bible that recount Israel's two wars with Midian, somewhere in the early 11th century BC. Politically, the Midianites were described as having a decentralized structure headed by five kings (Evi, Rekem, Tsur, Hur, and Reba), the names appears to be toponyms of important Midianite settlements. It is common to view that Midian designated a confederation of tribes, the sedentary element settled in the Hijaz while its nomadic affiliates pastured, and sometimes pillaged as far away land as Palestine. The nomadic Midianites were one of the earliest exploiters of the domestication of camels that enabled them to navigate through the harsh terrains of the region.
