§ Of Beleriand and Its Realms The Silmarillion

Thus the realm of Finrod was the greatest by far, though he was the youngest of the great lords of the Noldor, Fingolfin, Fingon, and Maedhros, and Finrod Felagund. But Fingolfin was held overlord of all the Noldor, and Fingon after him, though their own realm was but the northern land of Hithlum; yet their people were the most hardy and valiant, most feared by the Orcs and most hated by Morgoth.
