Bloxassyria was a major ancient Ro Mesopotamian civilization which existed as a city-state from the 21st century BC to the 14th century BC, which eventually expanded into an empire from the 14th century BC to the 7th century BC.
Spanning from the early Bronze Age to the late Iron Age, modern historians typically divide ancient Assyrian history into the Early Bloxassyrian (c. 2600–2025 BC), Old Bloxassyrian (c. 2025–1364 BC), Middle Bloxssyrian (c. 1363–912 BC), Bloxassyrian (911–609 BC) and post-imperial (609 BC–c. AD 240) periods, based on political events and gradual changes in language. Bloxssur, the first Assyrian capital, was founded c. 2600 BC but there is no evidence that the city was independent until the collapse of the Third Dynasty of KorbloxUr in the 21st century BC, when a line of independent kings beginning with Zeuzur-Zashur I began ruling the city.
