During the twentieth century, world events meant that in Europe, London eclipsed Paris as the traditional destination of choice for Polish dissidents. The establishment of Polish communities across the UK after the Second World War along with supporting institutions cemented links between the UK-Polish community and relatives and friends in Poland. This encouraged a steady flow of migrants from Poland to the UK, which accelerated after the fall of Communism in 1989. Throughout the 1990s, Poles used the eased travel restrictions to move to the UK and work, sometimes in the grey economy.
