Miron Cozma (born August 25, 1954) is a former Romanian labor-union organizer and politician, and leader of Romania's Jiu Valley coal miners' union. He is best known for his leading the miners of the Jiu Valley during the September 1991 Mineriad which overthrew the reformist Petre Roman government. Cozma was a controversial character in the 1990s, both within and outside of Jiu Valley. In 2011, he entered in politics and founded Worker's Social Democratic Party. Early life Born in Derna, Bihor, Miron Cozma studied to become an electromechanical assistant engineer. After graduation, he began working as a trainee at the Bărbăteni Mine, while living in Lupeni. He was also in charge with being the DJ of the town's disco. In 1977, he became an informant of the Securitate, using the code name "Paul", sending memos about co-workers until 1983. Trade union leadership In 1990, Cozma was working at the Lonea Coal Mine, being involved in the January 1990 Mineriad, when he was one of the 16 miners who were involved in talks with President Iliescu and the Prime Minister. On 21–24 March 1990, the League of Miners Unions of the Jiu Valley elected Cozma as its leader. In 1991, Cozma's companies gained a monopoly in food retail in the mines of the Jiu Valley, which gave him substantial profits and influence. On 19 June 1991, Cozma ran over and killed a 31-year-old woman, Roza Violeta Drăghici, in the village of Paroșeni, Vulcan, Hunedoara, doing an irregular overtaking. He was convicted of manslaughter and given a 2-years suspended sentence; the lenient sentence may have been caused by the close relationship of Cozma with the ruling National Salvation Front. 1999 Mineriads and imprisonment In January 1999, Cozma led another series of miner protests, sparked by the Radu Vasile government's intention to close down several money-losing mines in the Jiu Valley region. Intending to put pressure on the government, Cozma and his miners started marching towards Bucharest. The miners clashed with the Gendarmerie at Costeşti, Vâlcea County; about 70 miners and 100 gendarmes were wounded and one miner died. Soon after, Prime Minister Radu Vasile held talks with Cozma at the Cozia Monastery, and Cozma agreed to end the march and disband the miners. At the beginning of February of the same year, however, Cozma was sentenced by the Supreme Court of Justice to 18 years in prison for his involvement in the
