Ethiopia
The line of rulers of the actual Axumite kings ended around 950 AD when they were overthrown by the Jewish Queen Gudit; then it was followed by the Zagwe dynasty for around 300 years. Around 1270 AD, the Solomonid dynasty came to control Ethiopia, claiming that they were related to the kings of Axum (though their claim was unscientific, they were even southern Ethiopia people, like from Shewa and such). They called themselves Neguse Negest ("King of Kings," or Emperor), basing their claims on their direct relation to king Solomon and the queen of Sheba.
