Israel was not invented. It is an alternate name for Jacob of the Old Testament. His descendants were called "the children of Israel."
Israel was also the name of one of two ancient Jewish kingdoms, the other being Judah. The ancient Kingdom of Israel existed as an independent entity form about 1050 BC until about 930 BC.
Because the ancient Kingdom of Judah lasted until the Babylonian conquest, and was afterward a province of Babylon, Macedon and then Rome under the names of Yehud or Judea, modern efforts to found a Jewish state preferred the name Israel.
The modern State of Israel was founded in 1948.
