Svetozar Marović is a Montenegrin lawyer and politician who served as the last head of state and head of government of Serbia and Montenegro from 2003 until Montenegro's declaration of independence in 2006.

The Democratic Party of Socialists of Montenegro is a social-democratic and populist political party in Montenegro. A former long-time ruling party sitting at the opposition for the first time as of 2020, it was formed on 22 June 1991 as the successor of the League of Communists of Montenegro, which had governed Montenegro within the Socialist Federal Republic of Yugoslavia since World War II, and has remained a major force in the country ever since. The party is a member of the Socialist International and the Progressive Alliance, and an associate of the Party of European Socialists. During the 1990s, DPS was the major centre-left, social-democratic party in favour of Serbian–Montenegrin unionism. However, since 1997, the party has embraced Montenegrin independence and has been improving ties with the West, slowly turning into a catch-all party embracing Atlanticism, Montenegrin nationalism, neoliberalism, and pro-Europeanism.
