The submission of the northern tribes was with difficulty obtained by a long and fierce struggle, which--so far as one belligerent was concerned -- terminated in a compromise.

Ambris was deposed, and his country placed under an Assyrian governor; Mita consented, after many years of resistance, to pay a tribute; Urza was defeated, and committed suicide, but the general pacification of the north was not effected until a treaty was made with the king of Van, and his good-will purchased by the cession to him of a considerable tract of country which the Assyrians had previously taken from Urza.
On the side of Media the resistance offered to the arms of Sargon seems to have been slighter, and he was consequently able to obtain a far more complete success.

Having rapidly overrun the country, he seized a number of the towns and "annexed them to Assyria," or, in other words, reduced a great portion of Media into the form of a province.

He also built in one part of the country a number of fortified posts.

He then imposed a tribute on the natives, consisting entirely of horses, which were perhaps required to be of the famous Nisaean breed.
After his fourteenth year, B.C.708, Sargon ceased to lead out his troops in person, employing instead the services of his generals.
