The Himyarite Kingdom was a polity in the southern highlands of Yemen, as well as the name of the region which it claimed. Until 110 BCE, it was integrated into the Qatabanian kingdom, afterwards being recognized as an independent kingdom. According to classical sources, their capital was the ancient city of Zafar, relatively near the modern-day city of Sana'a. Himyarite power eventually shifted to Sana'a as the population increased in the fifth century. After the establishment of their kingdom, it was ruled by kings from dhū-Raydān tribe. The kingdom was named Raydān.

Ẓafār, also called Dhafar or Dhofar, is an ancient Himyarite site situated in Yemen, some 130 km south-south-east of today's capital, Sana'a, and c. 10 kilometres (6.2 mi) southeast of Yarim. Given mention in several ancient texts, there is little doubt about the pronunciation of the name. Despite the opinion of local patriots in Oman, this site in Yemen is far older than its namesake there. It lies in the Yemeni highlands at some 2800 m. Zafar was the capital of the Himyarites, which at its peak ruled most of the Arabian Peninsula. For 250 years the tribal confederacy and allies' combined territory extended past Riyadh to the north and the Euphrates to the north-east.
