The blockade of the Gaza Strip refers to a land, air, and sea blockade on the Gaza Strip by Israel and Egypt from 2007 to present. After the 2005 disengagement from the Gaza Strip by Israel, in 2006, Hamas won the Palestinian legislative election, triggering the 2006–07 economic sanctions against the Palestinian National Authority by Israel and the Quartet on the Middle East after Hamas refused to quit violence, respect previous agreements and recognize Israel. In March 2007, Hamas and Fatah formed a Palestinian authority national unity government headed by Ismail Haniya. Shortly after, in June, Hamas took control of the Gaza Strip in the course of the Battle of Gaza, seizing government institutions and replacing Fatah and other government officials with its own. Following the takeover, Egypt and Israel largely sealed their border crossings with Gaza, on the grounds that Fatah had fled and was no longer providing security on the Palestinian side.
Israel maintains that the blockade is necessary to limit Palestinian rocket attacks from the Gaza Strip on its cities and to prevent Hamas from obtaining other weapons. Prior to its 2011 opening of the Rafah crossing, Egypt maintained that it could not fully open its side of the border since completely opening the border would represent Egyptian recognition of the Hamas control of Gaza, undermine the legitimacy of the Palestinian National Authority and consecrate the split between Gaza and the West Bank.
