Other important criteria throughout history are that the major powers should have sufficient influence to be involved in discussions on current political and diplomatic issues and influence the end result and solution. Historically, several major powers have met to discuss it when major political issues have been raised. Before the era of groups such as the United Nations, participants in such meetings were not officially appointed, but chosen on the basis of their status as great power. These were conferences that addressed important issues on the basis of important historical events. In a largely peaceful transition, the Ottoman provinces of Moldova and Wallachia slowly interrupted, gained effective autonomy in 1859 and officially became an independent nation in 1878. Both provinces have long been under Ottoman control, but Russia and Austria wanted them too, making the region a place of conflict in the 19th century. The population was largely Orthodox in religion and spoke Romanian, but there were many minorities, like Jews and Greeks. The provinces were occupied by Russia under the Treaty of Adrianopel in 1829. Russian and Turkish troops united to suppress the Valachian revolution of 1848. During the Crimean War, Austria took control.
The population has chosen to unite on the basis of historical, cultural and ethnic ties. It came into force in 1859, after the election of Alexandru Ioan Cuza reigning prince of the United Princes of Moldova and Wallachia (renamed Romania in 1862).  In the 1850s, railway and telegraph lines connected all major cities in Western Europe, as well as cities without cities in Western Europe and the United States. Instead of significantly reducing travel requirements, the Telegraph has facilitated travel planning and replaced the slow distance mail service.  Submarine cables were installed to connect continents by telegraph, which was a reality in the 1860s.    The papacy secured France`s support for opposing the union, fearing that the abandonment of control of the papal states would weaken the Church and allow liberals to dominate conservative Catholics.  The Kingdom of Italy finally recaptured the papal states in 1870, when the French army was withdrawn. The angry pope has declared himself a prisoner; his successor, Pope Pius XI, finally made peace with Italy in 1929.  After 1870, Italy was recognized as the sixth great power, although much weaker than the others.
 China, France, Russia, the United Kingdom and the United States are often referred to as great powers by academics because of their “political and economic dominance on the world stage.”  These five nations are the only states with permanent veto seats on the UN Security Council.
