High Quality Content by WIKIPEDIA articles! In J. R. R. Tolkien's Middle-earth legendarium, the Kings of Númenor were Dúnedain men who ruled the kingdom of Númenor. Númenor's twenty-five rulers are listed in simple form at List of rulers of Númenor. More details about the reigns of the rulers are given here, for the twenty-three male rulers, including one usurper, and at Ruling Queens of Númenor for the female rulers. Elros Tar-Minyatur was born in year 525 of the First Age to Eärendil and Elwing. Elros' name may mean "Elf of the Spray". Christopher Tolkien interprets Elros as meaning "Star-foam". Elros was one of the Half-elven of Middle-earth who chose to become a mortal man. In S.A. 32 Elros became the first King of Númenor, taking the Quenya name Tar-Minyatur, meaning "High First-ruler". The Valar also granted Elros and his heirs substantially longer life-spans. He had four children and ruled for 410 years until his death in S.A. 442 at age 500.
