Tar-Ancalimon - "He was born in the year 1986, and ruled for 165 years, until his death in 2386.  In his time the rift became wider between the King's Men (the larger part) and those who maintained their ancient friendship with the Eldar." ~Unfinished Tales (The Line of Elros: Kings of Númenor)

"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." ~The Silmarillion (Akallabêth)
