Revolutions, Nationalism, and Unification: Europe and the Americas

Unsuccessful Revolutions in Europe: Following the successful overthrow of King Louis $XVI$ in France, other European countries like Austria and Hungary experienced revolutions in $1848$ . These revolutions, inspired by the French precedent, aimed to establish more democratic systems but were largely unsuccessful.
Emergence of Nationalism: Despite the failures of the $1848$ revolutions, a new concept of nationalism gained prominence. This ideology encouraged people to unite based on shared characteristics such as a common language, history, and religion, believing this unity could create a powerful force.
Napoleon's Influence on Nationalism: The rise of nationalism was significantly inspired by Napoleon's conquests. When Napoleon conquered vast territories across Europe, only about $15\%$ of the land consisted of French-speaking people, while the remaining $85\%$ were non-French. This led to a sentiment among the conquered people of not wanting to be part of the French Empire, desiring their own countries instead.
Impact on Italian and German Unification: Nationalism became a powerful unifying force, particularly impacting the future unification of Italy and Germany.

Early Nationalist Movements: The unification of Italy began with a rallying cry for all Italians to fight for a homeland.
Giuseppe Mazzini ("The Heart"): Mazzini played a pivotal role, known as "the heart" of the movement. He founded an organization called "Young Italians" (or "Young Italy").
Purpose of Young Italy: This organization aimed to radicalize Italians across the peninsula, encouraging them to rise up and overthrow regional governments. They supported revolutionary movements across the area currently known as Italy, pushing for Italians to be in power.
Challenges and Sacrifices: Unifying Italy was difficult, often involving conflict against powers like the Austro-Hungarians. Nationalism, in this context, demanded a willingness to die for the dream of creating Italy, with the belief that even if one didn't live to see it, their children would. Men, particularly with figures like Garibaldi (though his direct actions are not detailed here), joined these movements.

Bismarck's Strategy: Bismarck aimed to unify all Germans by launching wars to gain territories and establish a new country, Germany, in Central Europe.
Long-lasting Impact on France: Bismarck's successful wars and the annexation of French land caused lasting resentment in France. French representatives at the World War I peace conference would later seek revenge, aiming to "bury Germany" due to Bismarck's actions.
"Germany First" Mentality: Bismarck believed that a country should always prioritize its own needs. He instilled a mentality in German politicians to "always put Germany first," leading to a political philosophy of power politics. This approach, prioritizing national interest above all else, was later cited by some as a contributing factor to World War I.
