In the 700s, Yemenis were among the first to join the new religion Islam. Since then, Yemenis have been staunch Muslims who were in the forefront of all Islam conquests. Men whose ancestors came from Yemen ruled Al-Andalus (Muslim Spain) for centuries. The Ottoman Empire took control of North Yemen, and the British Empire took South Yemen, in the early 20th century. The two parts were united in 1990 and later fought civil wars. The latest one started in 2015. Some famous people including former President Ali Abdullah Saleh were killed, and thousands died of hunger.
