The topic of my diploma thesis is the comparison between the Austrian Constitution of 1848 and the Belgium Constitution of 1831. First of all, the political, economic and social developments until the year of 1831 in Belgium, in which the independence tendencies were finally realized, are discussed. The years before 1831 were characterized by the policy of King William, who tried to force the harmonization between Belgium and the Netherlands. He missed, though, to fully adapt his plans to the originality of the Belgium people and therefore faced a lively opposition, which formed in 1828 the catholic-liberal union. Besides his political misstep, King William's economic aspirations turned Belgium into one of the role models of the Industrial Revolution. The huge leap forward in technology and industry had devastating effects on the social developments and left many people in poverty.The Revolution in 1831 led soon to the Belgium Constitution, which was proclaimed on February 7, 1831. It was characterized by the limitation of the king's influence, the liability of ministers and the bicameral system.In Austria, the years until 1848 were marked by the policy of restauration, which took its toll as well on the economic and social spheres. When the revolution shook up the country in March 1848, a constitution, which was called the Constitution of Pillersdorf, was instantly presented, namely on April 25, 1848. Nevertheless, the constitution was not ready to meet the expectations and was replaced by another in March 1849.The constitution of Pillersdorf, which was named after minister Pillersdorf, consisted as well of two chambers, limited the influence of the monarch and implemented the liability of ministers, but was overall not complex enough to be accepted by the people who craved for a change and a right to say in a matter.
