King of Doriath

From Tolkien Gateway

The King of Doriath was the title of two Elf-lords of the Sindar, who ruled the kingdom of Doriath for many centuries, from its foundation long before the beginning of the Years of the Sun, until its destruction at the hands of the Sons of Fëanor during the Second Kinslaying.[1][2]

Elu Thingol: The founder of Doriath with his queen, Melian. He was lord there for millennia, and in that time his realm was protected from foes by the Girdle of Melian (after the return of Morgoth). Thingol was slain by the Dwarves in F.A. 503, and Melian departed from the realm. Thingol was succeeded by their grandson, the son of their daughter Lúthien. As ruler, Thingol was further acknowledged as the high-king of the Sindar in Beleriand.[3]

Dior Eluchíl: After Thingol's death he came to Menegroth and ruled the kingdom of his grandfather. Because Dior's treasuries held a Silmaril, the Sons of Fëanor assailed the citadel of Menegroth to recover it. There Dior was slain, and the kingdom ended in F.A. 506.
