The West Bank, including East Jerusalem, has been under military occupation by Israel since 7 June 1967, when Israeli forces captured the territory, then ruled by Jordan, during the Six-Day War. The status of the West Bank as a militarily occupied territory has been affirmed by the International Court of Justice and, with the exception of East Jerusalem, by the Israeli Supreme Court. The official view of the Israeli government is that the laws of belligerent occupation do not apply to the territories, which it considers instead "disputed", and it administers the West Bank, excepting East Jerusalem, under the Israeli Civil Administration, a branch of the Israeli Ministry of Defense. Considered to be a classic example of an "intractable conflict", the length of Israel's occupation was already regarded as exceptional after two decades, and is now the longest in modern history. Israel has cited several reasons for retaining the West Bank within its ambit: a claim based on the notion of historic rights to this as a homeland as claimed in the Balfour Declaration of 1917; security grounds, both internal and external; and the deep symbolic value for Jews of the area occupied.

The Palestinian territories are the two regions of the former British Mandate for Palestine that have been occupied by Israel since the Six-Day War of 1967, namely the West Bank and the Gaza Strip. The International Court of Justice (ICJ) has referred to the West Bank, including East Jerusalem, as "the Occupied Palestinian Territory", and this term was used as the legal definition by the ICJ in its advisory opinion of July 2004. The term occupied Palestinian territory was used by the United Nations and other international organizations between October 1999 and December 2012 to refer to areas controlled by the Palestinian National Authority, but from 2012, when Palestine was admitted as one of its non-member observer states, the United Nations started using exclusively the name State of Palestine. The European Union (EU) also uses the term "occupied Palestinian territory". The government of Israel and its supporters use the label "disputed territories" instead.
