Yahya Ibrahim Hassan Sinwar was the leader of Hamas in Gaza and a central figure of the Palestinian resistance against Israeli occupation. His life journey from refugee camp childhood, to decades in Israeli prisons, to political and military leadership reflected the broader Palestinian experience of dispossession, endurance, and struggle.

Born in Khan Younis Refugee Camp in southern Gaza, Sinwar’s family were among the hundreds of thousands expelled during the 1948 Nakba. Growing up amid poverty and displacement, he was educated in local schools before studying Arabic at the Islamic University of Gaza, where he became active in Islamist student groups. His political activism intensified during the First Intifada, and in 1988 he was arrested by Israeli authorities and sentenced to four life terms on charges of involvement in militant operations. Sinwar spent 22 years in Israeli prisons, where he developed the intellectual and spiritual foundation of his leadership. He memorised the Qur’an, studied political and military strategy, and learned Hebrew, gaining insight into Israeli society and statecraft. Prison, he later reflected, was intended to “grind our will,” but instead became “a sanctuary of worship and an academy of study.” These years forged his reputation as one of Hamas’s most disciplined and ideologically committed leaders. In 2011, Sinwar was released and he quickly reasserted his role in Hamas, initially focusing on internal security and organisational discipline. In 2017, he was elected leader of Hamas in Gaza, succeeding Ismail Haniyeh, and in August 2024, following Haniyeh’s assassination in Tehran, he became the movement’s overall leader. As Hamas’s Gaza leader, Sinwar oversaw governance in a territory besieged by blockade and repeated military assaults. Beyond its political and military role, Hamas administered social services—schools, clinics, and welfare networks—vital to Gaza’s survival under siege. Sinwar played a central role in the October 7, 2023 attacks, which triggered a devastating Israeli military campaign in Gaza. In October 2024, Sinwar was killed in Rafah during a firefight with Israeli forces. Fighting until his final moments, his last seconds of life have become iconic in cementing his legacy as a symbol of resistance against overwhelming odds.
