The Paris Convention of 19 August 1858 and, especially, "Statutul Dezvoltător" ("The Expanding Statute") of that convention (which introduced a bicameral parliament, by founding "Corpul Ponderator", later renamed "Senat"), adopted on the initiative of prince ("Domnitor") Alexandru Ioan Cuza, by means of a plebiscite in 1864, perfected and enlarged the principle of national representation. Under the political regime established by the Paris Convention, the legislative power faced an obvious process of modernization, and the legislative power as National Representation, which operated in accordance with the organization and operation mode of parliaments in Western Europe at that time.
