Document 7: Aung San Suu Kyi: Aung San Suu Kyi was born on 19 June 1945 in Rangoon (now Yangon), British Burma. According to Peter Popham, she was born in a small village outside Rangoon called Hmway Saung. Her father, Aung San, allied with the Japanese during World War II. Aung San founded the modern Burmese army and negotiated Burma's independence from the British Empire in 1947; he was assassinated by his rivals in the same year. She grew up with her mother, Khin Kyi, and two brothers, Aung San Lin and Aung San Oo, in Rangoon. Aung San Lin died at the age of eight, when he drowned in an ornamental lake on the grounds of the house. Her elder brother emigrated to San Diego, California, becoming a United States citizen.

Document 9: Myanmar: For most of its independent years, the country has been engrossed in rampant ethnic strife and Burma's myriad ethnic groups have been involved in one of the world's longest-running ongoing civil wars. During this time, the United Nations and several other organisations have reported consistent and systematic human rights violations in the country. In 2011, the military junta was officially dissolved following a 2010 general election, and a nominally civilian government was installed. While former military leaders still wield enormous power in the country, Burmese Military have taken steps toward relinquishing control of the government. This, along with the release of Aung San Suu Kyi and political prisoners, has improved the country's human rights record and foreign relations, and has led to the easing of trade and other economic sanctions. There is, however, continuing criticism of the government's treatment of the Muslim Rohingya minority and its poor response to the religious clashes. In the landmark 2015 election, Aung San Suu Kyi's party won a majority in both houses, ending military rule.
