<P0-S0> 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. <P0-S1> Portuguese traders first settled in Macau in the 1550s. <P0-S2> In 1557, Macau was leased to Portugal from Ming China as a trading port. <P0-S3> 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. <P0-S4> Sovereignty over Macau was transferred back to China on 20 December 1999. <P0-S5> 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> <P1-S0> napoleon turned his focus to domestic affairs after the war. <P1-S1> empress joséphine had still not given birth to a child from napoleon, who became worried about the future of his empire following his death. <P1-S2> desperate for a legitimate heir, napoleon divorced joséphine in january 1810 and started looking for a new wife. <P1-S3> hoping to cement the recent alliance with austria through a family connection, napoleon married the archduchess marie louise, who was 18 years old at the time. <P1-S4> on 20 march 1811, marie louise gave birth to a baby boy, whom napoleon made heir apparent and bestowed the title of king of rome. <P1-S5> his son never actually ruled the empire, but historians still refer to him as napoleon ii. <SEP> <P2-S0> william pitt, who entered the cabinet in 1756, had a grand vision for the war that made it entirely different from previous wars with france. <P2-S1> as prime minister pitt committed britain to a grand strategy of seizing the entire french empire, especially its possessions in north america and india. <P2-S2> britain's main weapon was the royal navy, which could control the seas and bring as many invasion troops as were needed. <P2-S3> he also planned to use colonial forces from the thirteen american colonies, working under the command of british regulars, to invade new france. <P2-S4> in order to tie the french army down he subsidized his european allies. <P2-S5> pitt head of the government from 1756 to 1761, and even after that the british continued his strategy. <P2-S6> it proved completely successful. <P2-S7> pitt had a clear appreciation of the enormous value of imperial possessions, and realized how vulnerable was the french empire. <SEP> <P3-S0> Unhappy with this change of policy by the Portuguese government, Napoleon sent an army to invade Portugal. <P3-S1> On 17 October 1807, 24,000 French troops under General Junot crossed the Pyrenees with Spanish cooperation and headed towards Portugal to enforce Napoleon's orders. <P3-S2> This attack was the first step in what would eventually become the Peninsular War, a six-year struggle that significantly sapped French strength. <P3-S3> Throughout the winter of 1808, French agents became increasingly involved in Spanish internal affairs, attempting to incite discord between members of the Spanish royal family. <P3-S4> On 16 February 1808, secret French machinations finally materialized when Napoleon announced that he would intervene to mediate between the rival political factions in the country. <P3-S5> Marshal Murat led 120,000 troops into Spain and the French arrived in Madrid on 24 March, where wild riots against the occupation erupted just a few weeks later. <P3-S6> Napoleon appointed his brother, Joseph Bonaparte, as the new King of Spain in the summer of 1808. <P3-S7> The appointment enraged a heavily religious and conservative Spanish population. <P3-S8> Resistance to French aggression soon spread throughout the country. <P3-S9> The shocking French defeat at the Battle of Bailén in July gave hope to Napoleon's enemies and partly persuaded the French emperor to intervene in person. <SEP> <P4-S0> 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).
