full_context: Document 1: Ho Chio Meng: Ho's ancestors moved to Macau from Panyu, Guangdong Province, in 1824, and he belongs to the fifth generation of his family to have lived in the enclave. He was born in Macau, and, as a child, he moved with his family to Mainland China in 1958, where he remained for the next three decades.
Document 2: Portugal: Portugal lost much of its wealth and status with the destruction of Lisbon in a 1755 earthquake, occupation during the Napoleonic Wars, and the independence of Brazil, its wealthiest colony, in 1822. After the 1910 revolution deposed the monarchy, the democratic but unstable Portuguese First Republic was established, later being superseded by the "Estado Novo" right-wing authoritarian regime. Democracy was restored after the Portuguese Colonial War and the Carnation Revolution in 1974. Shortly after, independence was granted to all its colonies, with the exception of Macau, which was handed over to China in 1999. This marked the end of the longest-lived European colonial empire, leaving a profound cultural and architectural influence across the globe and a legacy of over 250 million Portuguese speakers today.
Document 3: Portugal: The early history of Portugal is shared with the rest of the Iberian Peninsula located in South Western Europe. The name of Portugal derives from the joined Romano-Celtic name Portus Cale. The region was settled by Pre-Celts and Celts, giving origin to peoples like the Gallaeci, Lusitanians, Celtici and Cynetes, visited by Phoenicians and Carthaginians, incorporated in the Roman Republic dominions as Lusitania and part of Gallaecia, after 45 BC until 298 AD, settled again by Suebi, Buri, and Visigoths, and conquered by Moors. Other influences include some 5th-century vestiges of Alan settlement, which were found in Alenquer (old Germanic Alankerk, from Alan+kerk; meaning church of the Alan (people), Coimbra and Lisbon.
Document 4: Macau: Macau was formerly a colony of the Portuguese Empire, after Ming China leased the territory as a trading post in 1557. Originally governing under Chinese authority and sovereignty, Portugal was given perpetual occupation rights for Macau in 1887. Macau remained under Portuguese control until 1999, when it was returned to China. As a special administrative region, Macau maintains a separate political and economic system apart from mainland China.
Document 5: East India Company: The East India Company (EIC), also known as the Honourable East India Company (HEIC) or the British East India Company and informally as John Company, was an English and later British joint - stock company. It was formed to trade in the Indian Ocean region, initially with Mughal India and the East Indies (Maritime Southeast Asia), and later with Qing China. The company ended up seizing control over large parts of the Indian subcontinent, colonized parts of Southeast Asia, and colonized Hong Kong after a war with Qing China.
Document 6: Manuel John Johnson: 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).
Document 7: Bermuda: The island experienced large-scale immigration over the 20th century, especially after the Second World War. Bermuda has a diverse population including both those with relatively deep roots in Bermuda extending back for centuries, and newer communities whose ancestry results from recent immigration, especially from Britain, North America, the West Indies, and the Portuguese Atlantic islands (especially the Azores), although these groups are steadily merging. About 46% of the population identified themselves with Bermudian ancestry in 2010, which was a decrease from the 51% who did so in the 2000 census. Those identifying with British ancestry dropped by 1% to 11% (although those born in Britain remain the largest non-native group at 3,942 persons). The number of people born in Canada declined by 13%. Those who reported West Indian ancestry were 13%. The number of people born in the West Indies actually increased by 538. A significant segment of the population is of Portuguese ancestry (10%), the result of immigration over the past 160 years, of whom 79% have residency status.
Document 8: John Seward Johnson I: John Seward Johnson I (July 14, 1895 – May 23, 1983) was one of the sons of Robert Wood Johnson I (co-founder of Johnson & Johnson). He was also known as J. Seward Johnson Sr. and Seward Johnson. He founded the Harbor Branch Oceanographic Institution (HBOI), and was the grandfather of Jamie Johnson, who directed the documentary "Born Rich".
Document 9: Portugal: The Portuguese language is derived from the Latin spoken by the romanized Pre-Roman peoples of the Iberian Peninsula around 2000 years ago—particularly the Celts, Tartessians, Lusitanians and Iberians. In the 15th and 16th centuries, the language spread worldwide as Portugal established a colonial and commercial empire between 1415 and 1999. Portuguese is now spoken as a native language in five different continents, with Brazil accounting for the largest number of native Portuguese speakers of any country (200 million speakers in 2012).
Document 10: Guinea-Bissau: Portuguese natives comprise a very small percentage of Guinea-Bissauans. After Guinea-Bissau gained independence, most of the Portuguese nationals left the country. The country has a tiny Chinese population. These include traders and merchants of mixed Portuguese and Chinese ancestry from Macau, a former Asian Portuguese colony.
Document 11: Portugal: In 2007, Portugal had 10,617,575 inhabitants of whom about 332,137 were legal immigrants. In 2015, Portugal had 10,341,330 inhabitants of whom about 383,759 were legal migrants, making up 3.7% of the population. In 2017, Portugal had 416,682 legal residents of foreign origin, of which 203,753 identified as male, and 212,929 as female.Portugal's colonial history has long since been a cornerstone of its national identity, as has its geographic position at the south-western corner of Europe, looking out into the Atlantic Ocean. It was one of the last western colonial European powers to give up its overseas territories (among them Angola and Mozambique in 1975), turning over the administration of Macau to the People's Republic of China at the end of 1999. Consequently, it has both influenced and been influenced by cultures from former colonies or dependencies, resulting in immigration from these former territories for both economic and personal reasons. Portugal, long a country of emigration (the vast majority of Brazilians have Portuguese ancestry), has now become a country of net immigration, and not just from the last Indian (Portuguese until 1961), African (Portuguese until 1975), and Far East Asian (Portuguese until 1999) overseas territories. An estimated 800,000 Portuguese returned to Portugal as the country's African possessions gained independence in 1975.Since the 1990s, along with a boom in construction, several new waves of Ukrainian, Brazilian, Lusophone Africans and other Africans have settled in the country. Romanian, Moldovans, Kosovar and Chinese have also migrated to the country. Portugal's Romani population is estimated to be at about 40,000. Numbers of Venezuelan, Pakistani and Indian migrants are also significant.
Document 12: Handover of Hong Kong: The transfer of sovereignty over Hong Kong, commonly known as the handover of Hong Kong (or simply ``the Handover '', also`` the Return'' in mainland China) was the transition of control over the former British colony of Hong Kong from the United Kingdom to the People's Republic of China on 1 July 1997. The returned territory comprised Hong Kong Island and the Kowloon Peninsula, which were respectively ceded to Britain in 1842 and 1860, as well as the New Territories, which were leased for 99 years from 1898. The transfer was arranged to coincide with the expiration of this lease on the previous day, 30 June 1997. This event marked the end of British rule in Hong Kong, and is regarded by some as the end of the British Empire.
Document 13: Portuguese Malacca: The Dutch with their local allies assaulted and finally wrested Malacca from the Portuguese in January 1641. This combined Dutch - Johor - Aceh efforts effectively destroyed the last bastion of Portuguese power, reducing their influence in the archipelago. The Dutch settled in the city as Dutch Malacca, however the Dutch had no intention to make Malacca their main base, and concentrated on building Batavia (today Jakarta) as their headquarters in the orient instead. The Portuguese ports in the spice - producing areas of Mollucas also fell to the Dutch in the following years. With these conquests, the last Portuguese colonies in Asia remained confined to Portuguese Timor, Goa, Daman and Diu in Portuguese India and Macau until the 20th century.
Document 14: Macau: Macau was administered by the Portuguese Empire and its inheritor states from the mid-16th century until late 1999, when it constituted the last remaining European colony in Asia. Portuguese traders first settled in Macau in the 1550s. In 1557, Macau was leased to Portugal from Ming China as a trading port. 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. 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.
Document 15: John Michel: Born the son of Lieutenant-General John Michel and Anne Michel (née Fane), Michel was educated at Eton College and commissioned into the 57th Regiment of Foot on 3 April 1823. He transferred to the 27th Regiment of Foot a few months later, then to the 60th Regiment of Foot on 6 November 1823 and then to the 64th Regiment of Foot in Gibraltar on 24 November 1823.
