§ Akallabêth The Silmarillion

Then Tar-Ancalimon, son of Atanamir, became King, and he was of like mind; and in his day the people of Númenor became divided. On the one hand was the greater party, and they were called the King's Men, and they grew proud and were estranged from the Eldar and the Valar. And on the other hand was the lesser party, and they were called the Elendili, the Elf-friends; for though they remained loyal indeed to the King and the House of Elros, they wished to keep the friendship of the Eldar, and they hearkened to the counsel of the Lords of the West. Nonetheless even they, who named themselves the Faithful, did not wholly escape from the affliction of their people, and they were troubled by the thought of death.
