What is the birth of Israel?

The birth of Israel as a nation can be traced back to Jacob's struggle with the angel of God. After Jacob fought the angel, God named him Israel, and this became the name that refers to Jacobs offspring who evolved into the nation of 12 tribes. The birth of modern Israel happened at the end of British occupied Palestine (what is now called Israel) after ww2 when the Jews of the diaspora returned to their native homeland and transformed it into a modern nation state.
