Moshoeshoe I was the first king of Lesotho. He was the first son of Mokhachane, a minor chief of the Bamokoteli lineage, a branch of the Koena (crocodile) clan. In his youth, he helped his father gain power over some other smaller clans. At the age of 34 Moshoeshoe formed his own clan and became a chief. He and his followers settled at the Butha-Buthe Mountain. He became the first and longest-serving King of Lesotho in 1822.
