Hong Kong
From 1841 to 1981, Hong Kong was a British Crown Colony. From 1981 to 1997, Hong Kong was a British Dependent territory. In 1997 a hundred-something old treaty between the UK and China ran out, and China wanted Hong Kong back. One of the stipulations on the transfer of the territory was that Hong Kong would be partially self-governing and semi-democratic for at least forty years, even though the UK holds literally NO power over and has no say in anything to do with Hong Kong anymore.
