When was Israel named Israel?

The name "Israel" comes from a name given to the Patriarch Jacob. The kingdom of Israel was formed around 1020 BCE. In about 930 BCE, Israel and Judah split, and Israel existed independently of Judah until around 720 BCE, when it was conquered by Assyria and its members were sent into exile.

Since then, the land was called by different names (Judea, Syria Palaestina, Palestine) until 1948, when the modern country of Israel was declared.
