In traditions which are probably ancient, the race of their kings was derived from him, and after him was called the mighty city which ultimately became their capital.

As early as the thirteenth century B.C.the name of Nin was used as an element in royal appellations; and the first king who has; left us an historical inscription regarded himself as being in an especial way under Nin's guardianship.

Tiglath-Pileser I., is "the illustrious prince whom Asshur and Nin have exalted to the utmost wishes of his heart." He speaks of Nin sometimes singly, sometimes in conjunction with Asshur, as his "guardian deity." Nin and Nergal make his weapons sharp for him, and under Nin's auspices the fiercest beasts of the field fall beneath them.

Asshur-izir-pal built him a magnificent temple at Nimrud (Calah).

Shamas-Vul, the grandson of this king, dedicated to him the obelisk which he set up at that place in commemoration of his victories.
