Tar-Calmacil was the eighteenth ruler of Númenor. He succeeded his father, Tar-Alcarin, as king. His name means "Bright Sword", which he took in recognition of the territorial victories he had in Middle-earth as a renowned captain of Númenor.
Tar-Calmacil was also as the first king to have recorded an Adûnaic equivalent of his name: Ar-Belzagar . This signalled the rise of a faction known as the King's Men who were opposed to the Ban of the Valar.
There is a discrepancy in Tolkien's writings as to Tar-Calmacil's successor: Tar-Ardamin, his son, or Ar-Adûnakhôr, his grandson. Specifically, in Appendix A of Lord of the Rings, Ar-Adûnakhôr is listed as his successor, but in the more expanded "Line of Elros: Kings of Númenor" from Unfinished Tales, he is succeeded by Tar-Ardamin.
