Isa Mustafa (; born 15 May 1951) is a retired Kosovar politician. Mustafa was the mayor of Pristina from December 2007 to December 2013 and served as the prime minister of Kosovo between December 2014 and September 2017. He was the leader of the Democratic League of Kosovo (LDK) between 2010 and 2021. Early life Mustafa was born in the village of Prapashtica, in the Gollak Highlands of the District of Pristina, Kosovo on 15 May 1951, to Kosovo Albanian parents. He finished primary and high school in Pristina, and attended the University of Pristina in the Faculty of Economics, where he obtained a master's degree and a PhD. In 1974 he began his professional work, as an examiner at the University of Pristina. Political career Isa Mustafa began his political career in the early 1980s, when he became the head of the municipal government of Pristina, from 1984 to 1988. In the 1990s, as Yugoslavia started to break up, Mustafa became the Minister of Economy and Finances of the government of the Republic of Kosova, in exile, headed by Bujar Bukoshi. During this time, an arrest warrant for Mustafa was issued within Yugoslavia – which did not become international, making it possible for him to work in Western Europe. Mustafa did not apply for any political asylum, and was able to return to Kosovo anytime if needed. After the Kosovo War ended on 1999, he returned home, but returned to politics only in 2006 as a High Political Advisor of the then President of Kosovo, Fatmir Sejdiu. In December 2007, he became the mayor of Pristina in local elections, beating the vice president of the Democratic Party of Kosovo (PDK) and one of the ex-commanders of the Kosovo Liberation Army (UÇK), Fatmir Limaj. He won a second term as Mayor of Pristina in November 2009. On 7 November 2010, he became the leader of the Democratic League of Kosovo, beating Fatmir Sejdiu in the party leadership election by 235 votes to 124. On 1 December 2013, he lost re-election to the position of Mayor of Pristina, in what was seen as a major upset, to upcoming politician Shpend Ahmeti. The upset was especially dramatic seeing as it happened in what had been historically known as a Democratic League of Kosovo stronghold. On 8 December 2014, he became the Prime Minister of Kosovo in a coalition with the Democratic Party
