Prior to the establishment of the
federal state in 1848, the only central organ of
Switzerland was the Federal Diet (
Tagsatzung). Following the
Sonderbund War in 1847, the
Tagsatzung became responsible for drawing up the
Swiss Federal Constitution. The process of formulating
legislative power resulted in clashing opinions, in particular in relation to the representation of the various cantons: the
radicals, in the majority in the largest
cantons, pushed for a system where representation was purely proportional to the population of each township; the small cantons, for their part, feared being marginalized. After long debates, a compromise was found by adopting the American model of
bicameralism; the parliament will be composed of two chambers with equal power, and the agreement of both will be required to take a decision. The
National Council, which represents the people, will comprise representatives from each canton with their distribution being proportional to the population of the cantons, while the
Council of States, which represents the cantons, will be composed of the same number of representatives from each canton. According to the
Constitution of 1848, the Federal Assembly is "the supreme authority of the Confederation". The Council of States, meanwhile, was not modified until 1979, by adding two new seats for the
Canton of Jura which had just been created. ==Composition==
