Here is some information I found just searching the web. Netanyahu was born in 1949 in Tel Aviv. (The Jewish state was established in 1948) His mother, Tzila Segal (1912–2000), was born in Petah Tikva in the Ottoman Empire's Mutasarrifate of Jerusalem, and his father, Warsaw-born Benzion Netanyahu (né Mileikowsky; 1910–2012), was a historian specializing in the Jewish Golden age of Spain.
Netanyahu was chosen from Bibi's grandfather's first name Nathan.
"On May 14, 1948, David Ben-Gurion, the head of the Jewish Agency, proclaimed the establishment of the State of Israel. U.S. President Harry S. Truman recognized the new nation on the same day."
