Croatian political history at the turn of the nineteenth and twentieth century was strongly marked by the figure of Croatian ban Dragutin Khuen-Hedervary and by the National Party (Narodna stranka), political organization that formed a key pillar of his rule. It is impossible to fully understand this period without thorough research of the structure and functioning of the National Party as the strongest political organization and the ruling party with the immensely important role in political and social life of Croatia in that period. Khuen-Héderváry in a very short period of four years managed to break the power of the opposition, especially those of Party of Rights, to reinforce dualism and to become one of the pillars of dualism and the Monarchy in general. Simultaneously, Khuen conducted thorough transformation of the National Party which made her capable to preserve power during the next twenty-three years. In parliamentary elections the National Party won an absolute majority, largely due to restricted suffrage and large support by the administrative system that was directly involved in the electoral process.The National Party at the tops of its structure gathered a large estate, medium and higher educated citizenry, university professors, substantial part of the clergy, lawyers and notaries, the wealthy merchants, government employees and other dependent services. Therefore, the fact that the Party was quite far from the peasantry, which at the turn of the nineteenth and twentieth century still makes the vast majority of the population in Croatia, is hardly surprising. The National Party operated in certain organizational forms only in urban centers, but also often through the actions of administrative officials or local authorities which inclined towards Government and the National Party. In rural areas there are no similar forms of organization.
