Osama lliwat was born in Jerusalem and spent his early childhood there, but the family lost their Jerusalem residency when he was young (as they were not citizens) and were forced to move to the West Bank. As a youth, he lived in Jericho and was involved in the Palestinian resistance. 

Osama has been a dedicated peace activist for over fifteen years, working with organizations across the field, including the Sulha Peace Project, Interfaith Encounter Association, MJC ( Muslim Jewish conference), Combatants for Peace, and IPCRI. He speaks regularly for organizations and Universities all around the world. When Osama is not working for peace internationally, he helps his community in Jericho, and other communities in the West Bank, supporting them to stay on their land and rebuild homes, parks and schools. He also offers political educational tours in the West Bank and in 2011 he co-founded Visit Palestine, a political tourism company. 

Osama taught himself Hebrew in order to connect on the land. He also participates in trauma and healing work to support people on the land. He has participated in many different  trauma healing workshops in Israel/Palestine, and around the world, and believes deeply in the importance of creating save space for Israelis and Palestinians to heal on personal, social and political levels.

Osama was a speaker for TEDx Jaffa at the beginning of his peace journey, and featured in many television interviews including on the BBC in 2021 and NPR. He has also published an article in The Forward, and his work has been featured in newspapers across the world. He has also been featured in several documentaries, including Objector and The Other.
