What happened 705 AD

In 705, Justinian II returned to Constantinople with the armies of the Bulgarian khan Tervel, retook the throne, and instituted a reign of terror against his enemies.

Sargon II was succeeded by his son Sennacherib who moved the capital to Nineveh and made the deported peoples work on improving Nineveh's system of irrigation canals. Nineveh was transformed into the largest city in the world at the time.
