Misinai traces the beginning of the Arab–Israeli conflict and a Palestinian "Arab" identity to the simultaneous immigration of the Jews from various places and Brethren of Israel (from the east), to the land west of the Jordan river from 1840 to 1947. He states that by 1914 the Brethren of Israel became a very large group among Palestinians there and would remain so, until they were mostly expelled during the Palestinian exodus in 1948.[25] He argues that these people have now returned to their ancestral homeland east of the Jordan river, and possess no right to the land of Israel.[26]
