The most significant wave of Asian immigration to and settlement in the United Kingdom came following the Second World War, with the resumed control of Hong Kong, the breakup of the British Empire and the independence of Pakistan, India, Sri Lanka and later Bangladesh, especially during the 1950s and 1960s. An influx of Asian immigrants also took place following the expulsion or flight of Indian communities (then holders of British passports) from the newly independent Uganda, Kenya and Tanzania in the early 1970s.
