why the creation of the state of Israel has led to conflict between the Israelis and Palestinian Arabs.

The conflict between Israel and Palestina began with the creation of the State of Israel in 1948 and the conflict can be traced back when the Arabs opposed to Jewish immigration to Palestine after the end of WWII, as well as sectarian conflict in Mandatory Palestine.

The conflict is basically for the land when United Nations recommended the partition of Palestine into two states one Jewish and one Arab. The Jewish accepted the UN resolution but not the Arabs.
