Jews today generally call themselves Jews and consider the term Hebrews to be quaint, at best.In more detail, the Hebrews were a collection of related tribes in the middle east. Some of them claimed descent from a man named Israel, previously known as Jacob. They were called the Children of Israel or the Israelites, and they were also called Hebrews. The Israelites conquered (if the biblical account is to be believed) the land of Cannan and founded a kingdom, the Kindgom of David (there's evidence of this outside the Bible). Later, this kingdom split into a Northern kingdom, known as the Kingdom of Israel, and a southern kingdom, known as the Kingdom of Judah or Judea. The northern kingdom was wiped out by the Assyrian Empire. It's almost certain that some of the survivors joined up with the Judeans. The southern kingdom was wiped out by the Babylonian Empire (which also wiped out Assyria). After the Babylonian Empire was wiped out by the Persian Empire, the exiles who returned to Judea were known as Jews.
