The national movement to foster the social, political, and economic rejuvenation of Hungary began in earnest some twenty years before the Revolution of 1848. There was a direct line of development from the first reform diet of 1825, which demanded the redress of national grievances but no economic or social reform, to the last diet of feudal Hungary in 1847–1848, which demanded and obtained national sovereignty, the emancipation of the peasants, and the codification of basic human rights. During these years Hungary's political climate definitely changed, and every political group, even the court circles in Vienna, moved in what can be called a generally progressive or leftist direction. The court, the Hungarian chancellery in Vienna, the royal administration in Budapest, the conservative, liberal, and radical parties in the diet, and the extra-parliamentary opposition in the streets and the cafés—all assiduously planned, advocated, and introduced reform programs.
