Document 3: Kenya: Kenya is a presidential representative democratic republic. The president is both the head of state and head of government, and of a multi-party system. Executive power is exercised by the government. Legislative power is vested in both the government and the National Assembly and the Senate. The Judiciary is independent of the executive and the legislature. There was growing concern especially during former president Daniel arap Moi's tenure that the executive was increasingly meddling with the affairs of the judiciary.Kenya has a high degree of corruption according to Transparency International's Corruption Perception Index (CPI), a metric which attempts to gauge the prevalence of public sector corruption in various countries. In 2012, the nation placed 139th out of 176 total countries in the CPI, with a score of 27/100. However, there are several rather significant developments with regards to curbing corruption from the Kenyan government, for instance, the establishment of a new and independent Ethics and Anti-Corruption Commission (EACC).

Document 5: Mau Mau Uprising: On 20 October 1952, Governor Baring signed an order declaring a State of Emergency. Early the next morning, Operation Jock Scott was launched: the British carried out a mass - arrest of Jomo Kenyatta and 180 other alleged Mau Mau leaders within Nairobi. Jock Scott did not decapitate the movement's leadership as hoped, since news of the impending operation was leaked. Thus, while the moderates on the wanted list awaited capture, the real militants, such as Dedan Kimathi and Stanley Mathenge (both later principal leaders of Mau Mau's forest armies), fled to the forests.

Document 11: History of Malaysia: The Malayan Emergency as it was known, lasted from 1948 to 1960, and involved a long anti-insurgency campaign by Commonwealth troops in Malaya. The British strategy, which proved ultimately successful, was to isolate the MCP from its support base by a combination of economic and political concessions to the Chinese and the resettlement of Chinese squatters into “New Villages” in “white areas” free of MCP influence. In December 1948, 24 villagers were executed by British troops. From 1949 the MCP campaign lost momentum and the number of recruits fell sharply. Although the MCP succeeded in assassinating the British High Commissioner, Sir Henry Gurney, in October 1951, this turn to terrorist tactics alienated many moderate Chinese from the Party. The arrival of Lt.-Gen Sir Gerald Templer as British commander in 1952 was the beginning of the end of the Emergency. Templer invented the techniques of counter-insurgency warfare in Malaya and applied them ruthlessly. Although the insurgency was defeated Commonwealth troops remained with the backdrop of the Cold War. Against this backdrop, independence for the Federation within the Commonwealth was granted on 31 August 1957, with Tunku Abdul Rahman as the first prime minister.

Document 13: Gamal Abdel Nasser: Preceding the reform law, in August 1952, communist-led riots broke out at textile factories in Kafr el-Dawwar, leading to a clash with the army that left nine people dead. While most of the RCC insisted on executing the riot's two ringleaders, Nasser opposed this. Nonetheless, the sentences were carried out. The Muslim Brotherhood supported the RCC, and after Naguib's assumption of power, demanded four ministerial portfolios in the new cabinet. Nasser turned down their demands and instead hoped to co-opt the Brotherhood by giving two of its members, who were willing to serve officially as independents, minor ministerial posts.
Document 14: Gamal Abdel Nasser: On 5 March, Nasser's security coterie arrested thousands of participants in the uprising. As a ruse to rally opposition against a return to the pre-1952 order, the RCC decreed an end to restrictions on monarchy-era parties and the Free Officers' withdrawal from politics. The RCC succeeded in provoking the beneficiaries of the revolution, namely the workers, peasants, and petty bourgeois, to oppose the decrees, with one million transport workers launching a strike and thousands of peasants entering Cairo in protest in late March. Naguib sought to crackdown on the protesters, but his requests were rebuffed by the heads of the security forces. On 29 March, Nasser announced the decrees' revocation in response to the "impulse of the street." Between April and June, hundreds of Naguib's supporters in the military were either arrested or dismissed, and Mohieddin was informally exiled to Switzerland to represent the RCC abroad. King Saud of Saudi Arabia attempted to mend relations between Nasser and Naguib, but to no avail.
Document 15: Mau Mau Uprising: Aside from military operations against Mau Mau fighters in the forests, the British attempt to defeat the movement broadly came in two stages: the first, relatively limited in scope, came during the period in which they had still failed to accept the seriousness of the revolt; the second came afterwards. During the first stage, the British tried to decapitate the movement by declaring a State of Emergency before arresting 180 alleged Mau Mau leaders (see Operation Jock Scott below) and subjecting six of them to a show trial (the Kapenguria Six); the second stage began in earnest in 1954, when they undertook a series of major economic, military and penal initiatives.
