The Fatah–Hamas reconciliation process refers to a series of reconciliation attempts to resolve the hostility between Fatah and Hamas since the 2006—2007 Fatah–Hamas conflict and Hamas' subsequent takeover of the Gaza Strip.
Despite a number of agreements, those attempts have as of 2016 not been successful, with Hamas still executing full control of the Gaza Strip, despite the formation of the "unity government" in June 2014. Israel and the United States have effectively opposed reconciliation.
Until the First Intifada, Fatah was the sole dominating party in the Palestinian political arena, including the PLO. In 1987, Hamas arose as a resistance movement against the Israeli occupation. Following the Oslo Accords, the PLO, of which Fatah still was the dominant member, formally denounced armed resistance. Hamas refused to recognize Israel and opposed the Oslo Accords and subsequent agreements between the PLO and Israel. Under pressure of Israel and the international community, Fatah attempted to eliminate Hamas, especially after Mahmoud Abbas had succeeded Arafat as President of the Palestinian National Authority. Tensions mounted ahead the Israeli disengagement from Gaza in 2005 and culminated in the Battle of Gaza in June 2007, resulting in a split of the Palestinian government.
In reconciliation attempts, Hamas has mainly focussed on reform of the PLO and its inclusion in the organisation. After Hamas' victory in the 2006 elections, it unsuccessfully tried to run the PA Government due to Israeli and international boycott.
