on that ideological basis, he founded the croatian party of rights with his school friend eugen kvaternik in 1861. the party of rights was clerical, conservative, and pro-habsburg. its only concession to nationalism was hostility to the serbs who, since the incorporation of the "military frontiers" into croatia in 1868, made up a quarter of the population. starčević was the only parliamentary representative who agreed with kvaternik's draft constitution of 26 june 1861. he advocated the termination of the military frontier and persuaded parliament to pass on 5 august 1861 the decision annulling any joint business with austria.
