Khalil Ibrahim al-Wazir was a Palestinian leader and co-founder of the nationalist party Fatah. As a top aide of Palestine Liberation Organization (PLO) Chairman Yasser Arafat, al-Wazir had considerable influence in Fatah's military activities, eventually becoming the commander of Fatah's armed wing al-Assifa.

Palestinian nationalism is the national movement of the Palestinian people that espouses self-determination and sovereignty over the region of Palestine. Originally formed in the early 20th century in opposition to Zionism, Palestinian nationalism later internationalized and attached itself to other ideologies; it has thus rejected the occupation of the Palestinian territories by the government of Israel since the 1967 Six-Day War. Palestinian nationalists often draw upon broader political traditions in their ideology, such as Arab socialism and ethnic nationalism in the context of Muslim religious nationalism. Related beliefs have shaped the government of Palestine and continue to do so.
