Question: What currency is used by the country who controlled the birthplace of Manuel John Johnson as a colony?

The Portuguese currency is the euro (€), which replaced the Portuguese Escudo, and the country was one of the original member states of the eurozone. Portugal's central bank is the Banco de Portugal, an integral part of the European System of Central Banks. Most industries, businesses and financial institutions are concentrated in the Lisbon and Porto metropolitan areas—the Setúbal, Aveiro, Braga, Coimbra and Leiria districts are the biggest economic centres outside these two main areas.

Portuguese traders first settled in Macau in the 1550s. The Portuguese Empire administered the city under Chinese authority and sovereignty until 1887, when Macau became a colony through a mutual agreement between the two countries. Sovereignty over Macau was transferred back to China on 20 December 1999. In 1557, Macau was leased to Portugal from Ming China as a trading port. The Joint Declaration on the Question of Macau and Macau Basic Law stipulate that Macau operate with a high degree of autonomy until at least 2049, fifty years after the transfer. <SEP> He was born in Macao, China, the son of John William Roberts of the East India Company and was educated at Mr Styles' Classical Academy in Thames Ditton and at the Addiscombe Military Seminary for service in the East India Company (the HEIC).
