full_context: Document 1: Bahrain: According to a January 2006 report by the United Nations Economic and Social Commission for Western Asia, Bahrain has the fastest-growing economy in the Arab world. Bahrain also has the freest economy in the Middle East and is twelfth-freest overall in the world based on the 2011 Index of Economic Freedom published by the Heritage Foundation/"Wall Street Journal".
Document 2: People's Alliance for Democracy: The People's Alliance for Democracy (PAD) (, "Phanthamit Prachachon Pheu Prachathipatai") also called the National Liberation Alliance - กลุ่มพันธมิตรกู้ชาติ, "Klum Phanthamit Ku Chat", Thai Patriots Network or more commonly the Yellow Shirts - , "Suea Lueang" - is a Thai political movement and pressure group. It was originally a coalition of protesters against Thaksin Shinawatra, the former Prime Minister of Thailand. Its leaders included media-mogul Sondhi Limthongkul and Major General Chamlong Srimuang. The PAD was a chief player in the Thailand political crisis of 2005 to 2006, the 2008 crisis, and the Cambodian–Thai border stand-off. Its membership consisted mainly of ultra-royalist middle-class and working-class Bangkok residents and anti-Thaksin Southerners, supported by some factions of the Thai Army, some leaders of Democrat Party, and the members of the state-enterprise labor unions.
Document 3: British Empire: The Suez Crisis very publicly exposed Britain's limitations to the world and confirmed Britain's decline on the world stage, demonstrating that henceforth it could no longer act without at least the acquiescence, if not the full support, of the United States. The events at Suez wounded British national pride, leading one MP to describe it as "Britain's Waterloo" and another to suggest that the country had become an "American satellite". Margaret Thatcher later described the mindset she believed had befallen the British political establishment as "Suez syndrome", from which Britain did not recover until the successful recapture of the Falkland Islands from Argentina in 1982.
Document 4: Al Meethaq: Al Meethaq (جمعية ميثاق العمل الوطني), or the 'National Action Charter Society', is a liberal political party in Bahrain. It was founded by Sunni and Shia businessmen from well-known families in 2002.
Document 5: British Empire: In 1951, the Conservative Party returned to power in Britain, under the leadership of Winston Churchill. Churchill and the Conservatives believed that Britain's position as a world power relied on the continued existence of the empire, with the base at the Suez Canal allowing Britain to maintain its pre-eminent position in the Middle East in spite of the loss of India. However, Churchill could not ignore Gamal Abdul Nasser's new revolutionary government of Egypt that had taken power in 1952, and the following year it was agreed that British troops would withdraw from the Suez Canal zone and that Sudan would be granted self-determination by 1955, with independence to follow. Sudan was granted independence on 1 January 1956.
Document 6: Islamism: Roughly contemporaneous with Maududi was the founding of the Muslim Brotherhood in Ismailiyah, Egypt in 1928 by Hassan al Banna. His was arguably the first, largest and most influential modern Islamic political/religious organization. Under the motto "the Qur'an is our constitution," it sought Islamic revival through preaching and also by providing basic community services including schools, mosques, and workshops. Like Maududi, Al Banna believed in the necessity of government rule based on Shariah law implemented gradually and by persuasion, and of eliminating all imperialist influence in the Muslim world.
Document 7: British Empire: Though Britain and the empire emerged victorious from the Second World War, the effects of the conflict were profound, both at home and abroad. Much of Europe, a continent that had dominated the world for several centuries, was in ruins, and host to the armies of the United States and the Soviet Union, who now held the balance of global power. Britain was left essentially bankrupt, with insolvency only averted in 1946 after the negotiation of a $US 4.33 billion loan (US$56 billion in 2012) from the United States, the last instalment of which was repaid in 2006. At the same time, anti-colonial movements were on the rise in the colonies of European nations. The situation was complicated further by the increasing Cold War rivalry of the United States and the Soviet Union. In principle, both nations were opposed to European colonialism. In practice, however, American anti-communism prevailed over anti-imperialism, and therefore the United States supported the continued existence of the British Empire to keep Communist expansion in check. The "wind of change" ultimately meant that the British Empire's days were numbered, and on the whole, Britain adopted a policy of peaceful disengagement from its colonies once stable, non-Communist governments were available to transfer power to. This was in contrast to other European powers such as France and Portugal, which waged costly and ultimately unsuccessful wars to keep their empires intact. Between 1945 and 1965, the number of people under British rule outside the UK itself fell from 700 million to five million, three million of whom were in Hong Kong.

This was in contrast to other European powers such as France and Portugal, which waged costly and ultimately unsuccessful wars to keep their empires intact. Between 1945 and 1965, the number of people under British rule outside the UK itself fell from 700 million to five million, three million of whom were in Hong Kong.
Document 9: Natural Albania: Natural Albania () is a nationalist political party in Albania created in 2010 by Koço Danaj. The main objective of the party is to propose a pacific solution to establish Greater Albania. The idea of unification, has roots in the events of the Treaty of London in 1913, when roughly half of the predominantly Albanian territories and 40% of the population were left outside the new country's borders,
Document 10: Ministry of Works (Bahrain): The Ministry of Works (MOW) is responsible for all infrastructure services in the Kingdom of Bahrain, including the public road network, drainage systems, and public buildings. Its work—which encompasses strategic planning, design, development, construction, project management and maintenance—is carried out in accordance with the National Strategic Master Plan for Bahrain, outlook 2030. This national plan provides the legal framework for structural planning, strategic development and investment in the Kingdom, as well as a strong framework for development control
Document 11: Overseas military bases of the United Kingdom: The United Kingdom is still considered and remains a global power even into the 21st century; this is evidenced through the nation's 15 overseas military bases, making it second only to the United States in terms of total overseas bases worldwide. Currently, there is also the possibility of an additional two new bases being built in Oman and the United Arab Emirates in the near future. Note that both the United Arab Emirates and Oman were once under British rule, showing the impact of colonialism and the British armed forces military presence across the globe, even into the 21st century.
Document 12: Lucknow Pact: Muhammad Ali Jinnah, then a member of the Congress as well as the League, made both the parties reach an agreement to pressure the British government to adopt a more liberal approach to India and give Indians more authority to run their country, besides safeguarding basic Muslim demands. Jinnah is seen as the mastermind and architect of this pact.
Document 13: British Empire: In July 1956, Nasser unilaterally nationalised the Suez Canal. The response of Anthony Eden, who had succeeded Churchill as Prime Minister, was to collude with France to engineer an Israeli attack on Egypt that would give Britain and France an excuse to intervene militarily and retake the canal. Eden infuriated US President Dwight D. Eisenhower, by his lack of consultation, and Eisenhower refused to back the invasion. Another of Eisenhower's concerns was the possibility of a wider war with the Soviet Union after it threatened to intervene on the Egyptian side. Eisenhower applied financial leverage by threatening to sell US reserves of the British pound and thereby precipitate a collapse of the British currency. Though the invasion force was militarily successful in its objectives, UN intervention and US pressure forced Britain into a humiliating withdrawal of its forces, and Eden resigned.
Document 14: British Empire: While the Suez Crisis caused British power in the Middle East to weaken, it did not collapse. Britain again deployed its armed forces to the region, intervening in Oman (1957), Jordan (1958) and Kuwait (1961), though on these occasions with American approval, as the new Prime Minister Harold Macmillan's foreign policy was to remain firmly aligned with the United States. Britain maintained a military presence in the Middle East for another decade. In January 1968, a few weeks after the devaluation of the pound, Prime Minister Harold Wilson and his Defence Secretary Denis Healey announced that British troops would be withdrawn from major military bases East of Suez, which included the ones in the Middle East, and primarily from Malaysia and Singapore. The British withdrew from Aden in 1967, Bahrain in 1971, and Maldives in 1976.
Document 15: Elizabeth II: In 1956, the British and French prime ministers, Sir Anthony Eden and Guy Mollet, discussed the possibility of France joining the Commonwealth. The proposal was never accepted and the following year France signed the Treaty of Rome, which established the European Economic Community, the precursor to the European Union. In November 1956, Britain and France invaded Egypt in an ultimately unsuccessful attempt to capture the Suez Canal. Lord Mountbatten claimed the Queen was opposed to the invasion, though Eden denied it. Eden resigned two months later.
