What is the history of macau?

Macau was a Portuguese colony and both the first and last European colony in China. Portuguese traders first settled in Macau in the 16th century and subsequently administered the region until the handover on 20 December 1999. The Sino-Portuguese Joint Declaration and the Basic Law of Macau stipulate that Macau operates with a high degree of autonomy until at least 2049, fifty years after the transfer.
