Ivica Dačić in the context of "Accession of Serbia to the European Union"

The Socialist Party of Serbia (Serbian: Социјалистичка партија Србије, romanized: Socijalistička partija Srbije, abbr. SPS) is a social democratic and populist political party in Serbia. Ivica Dačić, the former prime minister of Serbia, has led SPS as its president since 2006.

SPS was founded in 1990 as a merger of the League of Communists of Serbia and Socialist Alliance of Working People of Yugoslavia with Slobodan Milošević as its first president. In the 1990 general elections, SPS became the ruling party of Serbia while Milošević was elected president of Serbia. During Milošević's rule, SPS relied on the Serbian Radical Party (SRS) from 1992 to 1993 while it later led several coalition governments with SRS, New Democracy, and Yugoslav Left. Mass protests against SPS were held in 1991, and after being accused of falsifying votes in major urban cities, such as Belgrade and Niš, 1996–1997 protests were also organised. The Democratic Opposition of Serbia coalition defeated SPS in the 2000 general elections but Milošević declined to accept the results. This resulted in Milošević's overthrow.

The First Agreement of Principles Governing the Normalisation of Relations, informally known as the Brussels Agreement (Serbian: Бриселски споразум / Briselski sporazum, Albanian: Marrëveshja e Brukselit), is an agreement to normalize relations between the governments of Serbia and Kosovo. The agreement, negotiated and concluded in Brussels under the auspices of the European Union, was signed on 19 April 2013. Negotiations were led by Serbian prime minister Ivica Dačić and Kosovo prime minister Hashim Thaçi, mediated by EU High Representative Catherine Ashton. The government of Serbia does not recognize Kosovo as a sovereign state, but began normalising relations with the government of Kosovo as a result of the agreement. In Belgrade, the agreement was criticized by protestors as a convalidation of Kosovo independence.
