Israel is a country, not a religion, so it doesn't have a founder in the same way a religion might. However, the three major monotheistic religions that have historical and religious connections to the region of Israel are Judaism, Christianity, and Islam.
Judaism: The religion most closely associated with the history of Israel is Judaism. It is one of the world's oldest monotheistic religions. While Judaism doesn't have a single founder, it traces its spiritual lineage to the biblical figures Abraham, Isaac, and Jacob, who are known as the patriarchs. Moses, who received the Ten Commandments on Mount Sinai, is another crucial figure in Jewish history.
Christianity: Christianity, which was founded on the teachings of Jesus of Nazareth (also known as Jesus Christ), has strong connections to Israel, particularly Jerusalem. Christians believe that Jesus is the Son of God and the Messiah and consider the New Testament as one of their holy scriptures. However, Christianity was established as a separate religion from Judaism, and its primary founder in that sense is Jesus.
Islam: Islam, founded by the Prophet Muhammad in the 7th century CE, has significant historical and religious ties to Israel as well. The city of Jerusalem, in particular, holds great religious importance in Islam. However, the religion's founding figure is the Prophet Muhammad.
