Why was Italy not unified after the Congress of Vienna (1815)?

Prior to the Vienna conference, the occupation of France had a major impact on Italy. The power of the church and the pope has decreased, the ownership of the land has changed, and the land has been redistributed. A new middle class is beginning to emerge. Agriculture has advanced, farmers have removed old feudal relationships and obligations. Then when Napoleon was defeated and the recovery of the old regime and monarch began, Italy again became a country divided into 11 independent countries, except for the small principality and the San Marino Republic.

With the settlement at the Vienna conference in 1815, Italy was completely fragmented. Congress has divided the territory between the winner of the Napoleonic war, France and the conflict with several European countries led by Napoleon I in 1799 and 1815. Many Italians admire the victory of Napoleon against the Austrians, the Italians do not like them, and the Republican idea was rooted in Italy's French domination area during the Napoleonic war. However, the Kingdom of Sardinia resurrected Piedmont (Piedmont), Nice, Savai and bought Genoa, but the settlement in Vienna restored Austrian peninsular rule.

But at first it is a map. The expansion supporting the unification of Italy really started in 1815 after the Vienna conference was divided by Napoleon Italy. In 1829, Italian principality, Modena and Reggio began to expand. It then advanced through the last unification of the country under the flag of the Italian kingdom (recently renamed Sardinian kingdom) in 1870. Pay close attention to the period from 1848 to 1949 (the first Italian Revolutionary War) and from 1859 to 1861 (Independent Second War and its impact).

After many years of turmoil at the Vienna conference in 1815, Italy and Germany were unified from the mid-19th century to the latter half, and the two countries were divided into many states. Because there are many similarities and differences in these unified processes, people can compare and contrast. In order to properly evaluate these situations, it is necessary to consider various factors leading to harmony and how to compare them. There are similarities between Italy and Germany, but in general these processes are very different.
