This is a list of rulers of Saba' and Himyar, ancient Arab kingdoms which are now part of present-day Yemen.
[1] The title Mukarrib (Old South Arabian: 𐩣𐩫𐩧𐩨, romanized: mkrb) was used by the rulers of Saba' along the title Malik (Old South Arabian: 𐩣𐩡𐩫, romanized: mlk).
[2] After the fall of Dhu Nuwas around 530 CE to the Aksumite Empire,[3] Yemen was open for foreign domination by the Aksumites and later the Sasanian Empire, both of whom installed local vassal rulers over the Yemeni people.
After the Aksumites successfully invaded and subsequently took control of Yemen, they appointed a native Christian as the vassal ruler of Saba' and Himyar.
However, later on actual Abyssinians would rule Saba' and Himyar temporarily until the Sasanian Empire conquered Yemen under request from the native Yemenis.
