When did AsSyria defeat Syria?

The term "AsSyria" seems to be a typographical error or misunderstanding, as it doesn't refer to a distinct entity. If you meant "Assyria," an ancient empire, it did not "defeat" modern Syria, as Syria as a nation-state emerged long after the fall of the Assyrian Empire, which collapsed around the 7th century BCE. Therefore, there isn't a historical event where Assyria defeated Syria as we understand it today.
