Answer:
180 years
Step-by-step explanation:
The world's first empire is generally attributed to the Akkadian Empire, which was established by Sargon of Akkad in the 24th century BCE (around 2334 BCE, according to some estimates). The Akkadian Empire is considered the first empire in human history because it was one of the earliest instances of a single ruler, Sargon, conquering multiple city-states and regions to create a centralized state under his rule.
The Akkadian Empire lasted for approximately 180 years, from its founding by Sargon of Akkad around 2334 BCE to its collapse in the late 22nd century BCE. The exact dates can vary depending on historical interpretations and sources, but it is generally accepted that the empire's duration was within this time frame.
