Introduction & Background

Macau or Macao (English: /məˈkaʊ/ⓘ; Template:IPA-pt; Chinese 澳門; Template:IPA-yue), officially the Macao Special Administrative Region of the People's Republic of China (MSAR),e is a city and special administrative region of China in the western Pearl River Delta by the South China Sea. With a population of about 680,00011 and an area of 32.9km2 (12.7sqmi), it is the most densely populated region in the world.

Formerly a Portuguese colony, the territory of Portuguese Macau was first leased to Portugal as a trading post by the Ming dynasty in 1557. Portugal paid an annual rent and administered the territory under Chinese sovereignty until 1887. Portugal later gained perpetual colonial rights in the Sino-Portuguese Treaty of Peking. The colony remained under Portuguese rule until 1999, when it was transferred to China. Macau is a special administrative region of China, which maintains separate governing and economic systems from those of mainland China under the principle of "one country, two systems".12 The unique blend of Portuguese and Chinese architecture in the city's historic centre led to its inscription on the UNESCO World Heritage List in 2005.13
