What empires were at the time of Amos?

During the time of the prophet Amos, which is generally dated to the 8th century BCE, the prominent empires included the Assyrian Empire, which was expanding its influence over the Near East, and the Kingdom of Israel, where Amos prophesied. The region was marked by political instability and social injustice, with the Assyrians exerting pressure on Israel and Judah. The Egyptian empire was also a significant power in the region, although its influence was waning during this period.
