The Himyarite Kingdom or Himyar

It was the dominant state in Arabia until 525 AD. The economy was based on agriculture. Foreign trade was based on the export of frankincense and myrrh. For many years it was also the major intermediary linking East Africa and the Mediterranean world. This trade largely consisted of exporting ivory from Africa to be sold in the Roman Empire. Ships from Himyar regularly traveled the East African coast, and the state also exerted a large amount of Influence both cultural religious and political to the trading cities of East Africa whilst the cities of East Africa remained independent. The Periplus of the Erythraean Sea describes the trading empire of Himyar and its ruler Charibael (Karab Il Watar Yuhan'em II), who is said to have been on friendly terms with Rome:

"23. And after nine days more there is Saphar, the metropolis, in which lives Charibael, lawful king of two tribes, the Homerites and those living next to them, called the Sabaites; through continual embassies and gifts, he is a friend of the Emperors."
