At the age of 18, Kálmán Tisza witnessed one of the greatest transformations of the political arena in Hungarian history. Hungary's political system changed from being a feudalistic state into a newly established constitutional monarchy that shared many components with modern-day governments. Legislation such as Public Law III abolished the Royal Chancellery and the Residential Council replacing them with a bicameral parliament (House of Lords and House of Representatives). Democratic principles were established with Public Law V that allowed 6.5% of the population to vote (Janos 85). Also, the union of traditional Magyar lands under Public Law VI and VII created a unified Hungary. These powerful reforms led to a nationalist revolt that culminated in the dethroning of the Habsburg dynasty during the Hungarian Revolution of 1848-49.
