By the close of the 20th century, the European colonial Empires had ceased to exist as significant global entities. Sunset for the British Empire came when Britain's lease on the great trading port of Hong Kong was brought to end, and political control was transferred to the People's Republic of China in 1997. Soon after, in 1999 Transfer of sovereignty over Macau was concluded between Portugal and China, bringing to a close six centuries of Portuguese colonialism. Britain remained culturally linked to its former empire through the voluntary association of the Commonwealth of Nations, and 14 British Overseas Territories remained (formerly known as Crown colonies), consisting mainly of scattered island outposts. Currently, 16 independent Commonwealth realms retain the British monarch as their head of state. Canada, Australia and New Zealand emerged as vibrant and prosperous migrant nations. The once vast French colonial empire had lost its major possessions though a scattered territories remained as Overseas departments and territories of France. The shrunken Dutch Empire retained a few Caribbean islands as constituent countries of the Kingdom of the Netherlands. Spain had lost its overseas possessions, but its legacy was vast – with Latin culture remaining throughout South and Central America. Along with Portugal and France, Spain had made Catholicism a global religion.
