The Assyrian Empire was the name given to one of the main nations in Mesopotamian history. The peak of the Assyrian State corresponds to the first half of the 1st millennium BC, while its origins date from the end of the 3rd millennium BC. Regarding geography, the core of the empire was made up of two areas. In the first place, it included the so-called triangle of Assyria, located between upper Zab and the Tigris, with Nineveh as its main center. And in second place, a little further south, was the city of Assur, which gave its name to the Assyrians themselves. For its part, the Assyrian triangle was an open region, widely populated, very rich seen from an agricultural perspective and that it also had an important and old town planning.
Shamshi-Adad I was responsible for leading the Assyrians beyond their core of origin for the first time. In addition, he managed to subdue all of Upper Mesopotamia, adding various territories of great relevance, an example of this is Mari, and in addition to that, he signed a peace treaty with Babylon, which would end up recognizing his dominions. Shamshi-Adad organized the new territories administratively, politically and militarily, establishing the first Assyrian territorial state; this is the time that is known as the Assyrian Old Empire.
Later, the Assyrian Middle Empire began with Assur-uballit I, who managed to escape from Mitanian tutelage, and, turning the situation around, also provisionally imposed on the Mitanni throne an Assyrian edge. Mitanni, now in decline, would eventually fall into the orbit of the Hittite Empire. For his part, Assur-uballit managed to control Assyria up to Upper Central Mesopotamia and the territories at the eastern ends of Mitanni. Seeing his great and renewed power, He called himself King of totality, and managed to establish direct diplomatic relations with the Egypt of Amenhotep IV, resulting in the angry protest of Burna-buriash of Babylon, which considered the Assyrians to be like slaves. Seeing the great power of the new Assyrian empire, Burna-buriash would end up recognizing the rank of Assur-uballit, and the reconciliation was sealed with a wedding: which took place between the son of the Babylonian with the daughter of the Assyrian.
