Luka Mornar was a Kruhlstutt politician and trade unionist who served as the long-serving leader of the Riverine Front, a regional party representing communities along Lake Vokavovic.
Mornar founded the Riverine Front at the 1964 General Election, the Kingdom’s first democratic contest following the 1964 Kruhlstutt Riots and constitutional reforms. He led the party through five consecutive elections — 1969, 1974, 1979, and 1984 — consistently campaigning on cross-border commerce, smuggling routes, and the economic interests of lake-adjacent cantons bordering the Divine Republic of Kresimiria.
The Riverine Front frequently held the balance of power in fragile SWL–Liberal coalitions, extracting concessions on border enforcement and freight transit through the lake.
