The nations of Austria, Holland, Russia combined forces to form an alliance against revolutions. They decided to unite to keep the legitimate rulers from collapsing and agreed to watch out for each others interest.
The new leader of France to joined this Alliance. This came to be known as the Holy Alliance.
The leaders of the alliance sent forces to suppress revolutions in each others territory and restore the rulers authority. Large number of spies were recruited, freedom of speech and press was curbed. But this didn't affect the revolutionaries spirit.
In 1830 revolutions began and french ruler was forced to abdicate. Though most of the revolts were crushed, freedom was won by Greece and Belgium.
1848 was a year when the spirit of revolution peaked across all European countries. The revolutions broke out and all states of the Holy Alliance were shaken by them. The monarchs had to give constitutional reforms to the people. Although few succeeded in overthrowing despots but the new social order was emerging. The monarch of France who came to power in 1848 was removed but soon replaced by Napoleon III. When the Empire of Napoleon III crumbled after the Prussian was , France became a republic.
The workers were the main leaders in the revolts. They wanted a new social order that would remove the ill effects of capitalism. But the others revolutionaries like peasants and middle class looked at these goals with horror. It wanted only constitutional reforms and so compromised with the rulers.
The 18th century Germany was divided into a number of states. Some of these were small as cities but some like Bavaria, Saxony, Prussia were powerful and large. During the Napoleonic war's some of these ceased to exist but by 1815 there were 38 territories in Germany.
Prussia was the largest and most powerful. It was dominated by landlords known as Junkers. Due to the division of Germany the political and social system was very backward. Civil liberties were absent. The French revolution had raised national consciousness amongst the Germans and they too wanted a united Germany.
In 1815 the Germanic states and Austria came together to form the German Confederation but each state wanted to maintain its own system and hence it failed. During 1848, revolutions broke out throughout German states and monarch's were forced to grant concessions to people. The leaders met at Frankfurt assembly to discuss the German constitution.
But the rulers were secretly planning to unite and crush the rebels. The Frankfurt assembly offered to the king of Prussia the title of Emperor of Germany and a united German nation. But the King refused to accept the offer of the rebels and sent forces to crush the revolts. The protests failed and all initial concessions to were withdrawn. Many rebels had to flee the country.
Bismarck belonged to aristocratic family in Prussia. He too wanted a united Germany but not a democratic empire but a militaristic one. He believed that there should be a domination of army and landed aristocrats in Germany.
To achieve this he followed a policy of war known as Blood and Iron. Under this he fought with Austria to ensure it was removed from the Germanic confederation. After Austria's defeat the 22 states of Germanic confederation were brought together under a single leader.
The French king Napoleon III too was provoked by Bismarck and he too waged a war on Prussia but was defeated. The war proved fruitful to Bismarck who absorbed the remaining German states into the German Empire.
The King of Prussia became the hereditary Emperor of Germany. Thus unlike the French revolution, the unification of Germany was due to a Policy of war. It was also not fought under the same ideals of Liberty, Equality, Fraternity. This was to bear fruit soon as such aggression led to the World War where Germany was defeated.
Like Germany, Italy too was divided into many states. Some like Lombardy were occupied by foreign powers, Large states like Sardinia, Kingdom of Two Sicily's and Rome were either under monarchs or under papal occupation.
Manzinni and Garibaldi were two great leaders of the unification movement. They started the Young Italy movement too start a rebellion against the monarchs. The work was dual as the people had to remove foreign occupation and convince the monarchs to unite.
The kingdom of Sardinia was the most powerful and the king to wanted the unification of Italy under him. He implemented many reforms after the 1848 revolts broke out. His PM Cavour followed Bismarck's policy and joined forces with France to fight Austria. Though France couldn't win Austria was ousted and Lombardy was recovered. Soon other smaller states in the Northern Italy became a part of Sardinia.
The Kingdom of Two Sicily and Rome were still outside Italian state. Garibaldi marched to these states with his revolutionaries and freed them. But the rebels couldn't continue this struggle and surrendered these kingdoms to Sardinia. The King now became the Emperor of Italy.
Rome was under Papal occupation and guarded by French soldiers. These were withdrawn after the French - Prussian war and Italy occupied it. Rome became the capital of Italy.
Just like Germany, Italy too saw a people's rebellion but it culminated in a monarchy. The difference between them is that the aristocracy united Germany whereas in Italy the popular revolt played an important role.
