Evidence: Andrija Mandić (Serbian Cyrillic: Андрија Мандић; born 19 January 1965) is a Montenegrin Serb politician. Serbs of Montenegro (Serbian: Срби у Црној Гори / Srbi u Crnoj Gori) or Montenegrin Serbs (црногорcки Cрби / crnogorski Srbi), compose the second largest ethnic group in Montenegro (28.7% of country's population), after the Montenegrins. Andrija Mandić decided to enter political life during his mid-twenties with the introduction of multi-party system in 1990 by joining the Union of Reform Forces of Yugoslavia (SRSJ). In the mid-1990s Andrija Mandic decided to return to political life and joined the People's Party, which claimed restoration of the old political party, the very first Montenegrin one, in the old Montenegrin monarchy.
