Adwan was born in 1952 in the town of Beit Hanoun, in the far north of the Gaza Strip, where he still resides, to a well-educated family. He earned a higher diploma in political science in Lebanon, probably in the early 1970s, a bachelor's degree in political science from the College of Economics and Political Sciences in Cairo in 1978, followed by a graduate diploma from the Center for Arab Research and Studies at the Beirut Arab University, and master’s and a PhD from British universities between 1983 and 1987. He became an associate professor in 1996 and a professor in political science in 2001 at the Islamic University of Gaza in Gaza City.[1]
In addition to his political posts, he is acting chairman of the Islamic Society in Beit Hanoun, preaches weekly at the Omar Bin Abed Al-Aziz mosque, and has published books and research papers on political issues such as the relationships between the Jews and the Muslims in the early stages of Islam.
Adwan has been arrested several times by the Israeli government for alleged terrorist activities and the PLO-led Palestinian Authority for political activism through the years. In 1992 he was deported to Marj Al-Zuhour in Southern Lebanon/[citation needed]
