3) A third set of more recent diasporas is organised chiefly around a political pole. This is particularly so when the territory of origin is dominated by a foreign power, and the main aspiration of the diaspora population is the creation of a nation-state. An example of this is the Palestinian diaspora: having succeeded in setting up a real state-in-exile, the Palestinian Liberation Organisation (PLO), whose objective of establishing a nation-state next to the state of Israel has already been partially achieved by the creation of the Palestinian Authority, which has been endowed with territories that it has administered since 1994. The Palestinian diaspora’s collective memory is rooted in the historical events that mark the trauma of dispersal and occupation, especially the catastrophe (nakba) of 1948. This is ‘the core event of their imagined community, the criterion of its alterity and the main founder of the diaspora’ (Kodmani-Darwish 1997: 194).
