General Soe Win (Burmese: စိုးဝင်း; pronounced [só wɪ́ɰ̃]; 10 May 1947 – 12 October 2007) was the Prime Minister of Burma and Secretary-1 of the State Peace and Development Council from 2004 to 2007. He was known by Burmese dissident groups as "the butcher of Depayin" for his role as mastermind of the 2003 Depayin Massacre, in which 70 National League for Democracy supporters were killed by a government-sponsored mob.
 Soe Win was born in 1947. After completing his Conscripted service in a Border Guards Unit, he joined the Military Academy and was commissioned into the Air Defence Branch of the Air Force in 1969. A graduate of the Defense Services Academy (12th intake), he took part in the crackdown on democracy protesters as a Brigade Commander in 1988, deploying troops around Rangoon University and ordering them to shoot at Rangoon General Hospital during the upheaval. He became Tactical Operations Commander 3 of the Northwestern Regional Command in 1990.
 In 1997 he was named Regional Commander and a member of the junta, then called the State Law and Order Restoration Council, or SLORC. In November 2001 he was named Air Defense General of the War Office. In February 2003 he was promoted to Secretary-2 of the junta, which was vacant after Lieutenant General Tin Oo was killed in a helicopter crash two years before.
 Soe Win is widely regarded as the mastermind behind the deadly attack against National League for Democracy leader Aung San Suu Kyi and her supporters in the 30 May 2003 Depayin Massacre. In 2014, former Prime Minister Khin Nyunt released a memoir attributing responsibility for the massacre to Soe Win, who he claimed was acting on the instructions of former junta leader Senior General Than Shwe.
 The same year he accompanied Senior General Than Shwe on state visits to Vietnam and China. Soe Win also signed the order to dismiss Foreign Minister Win Aung and his deputy in September 2003.
 Soe Win was appointed prime minister by State Peace and Development Council chairman Than Shwe on 19 October 2004. Soe Win succeeded Khin Nyunt, who officially had been "permitted to retire for health reasons", but the reformist-minded premier had actually fallen out of favor with Than Shwe. Khin Nyunt was later convicted by a special tribunal of corruption charges and sentenced to 44 years in prison.
 As Secretary-1 in the SPDC and prime minister, Soe Win was third in the leadership structure under Senior General Than Shwe and SPDC vice-chairman, Vice-Senior General Maung Aye. A senior member of the SPDC, Soe Win was close to Than Shwe, and the two men saw eye-to-eye on "nation building projects", which included constructing dams, roads and bridges.[citation needed]
 With his appointment as prime minister, he took a tougher line against political reform than did his immediate predecessor, Khin Nyunt. He was quoted as saying in January 2003 "the SPDC not only won’t talk to the NLD but also would never hand over power to the NLD."
 In March 2007, Soe Win was admitted to a private hospital in Singapore. The government was secretive about the nature of his illness, though it was reported in the media that he was suffering from leukemia. He returned to Burma on 3 May 2007, but then returned to Singapore later that month. The Burmese embassy in Singapore said he was being treated for a "serious health matter". In April 2007, Lieutenant General Thein Sein was appointed acting prime minister in Soe Win's absence. On 1 October 2007, in the wake of the anti-government protests, Soe Win returned to Burma. His condition was reported as "very ill" and he was admitted to a military hospital in Mingalardon Township, Rangoon.
 Soe Win's death was officially announced by the military authorities on 12 October. He died in Mingalardon Hospital, aged 60, from leukemia. His twin brother Major-General Tin Htun had died on 19 September 2007 of leukemia.
