Not only students, but other sources regularly refer to Assyria conquering Israel in 722 BCE.
This reflects a misunderstanding of the Bible and other evidence.
To talk about this as Assyria “conquering” Israel makes it sound as though Assyria was taking over for the first time. But it wasn’t. It was asserting its control over territories which it already possessed, and which were rebelling, expecting that support from Egypt and from one another would be sufficient to accomplish their aim of throwing off Assyrian rule.
They were wrong.
