Encylopedic History of the Twentieth Century: Economics, Politics, and Dictatorship

The Belle poque and the Fragile Optimism of Modernity

The start of the twentieth century in Europe was defined by an era known as the Belle poque, a period characterized by an unshakeable faith in progress and the fruits of the second industrial revolution. This climate of diffuse optimism was fueled by monumental achievements such as the advent of electricity, the use of petroleum, the mass production of automobiles, and the historic first flight of the Wright brothers in $1903$. During this time, Europe served as the undisputed economic center of the planet, and together with the United States, it accounted for $85\%$ of global industrial production. However, beneath this glittering facade, the continent was deeply fractured by a geographic economic divide. The "Center," comprised of north-western Europe, saw Germany overtake Great Britain as the primary economic power through heavy industry and armament production, positioning itself as the only true competitor to the surging United States. Conversely, the "Peripheries" consisted of newly industrializing zones like Northern Italy, Bohemia, and certain Russian regions, which coexisted with a dramatically backward Eastern and Mediterranean Europe still tethered to agricultural economies.

This economic asymmetry generated profound social tensions within individual states. The vast gap between the opulence of the new industrial elites and the misery of the working classes drove millions of Europeans to emigrate to the Americas. Consequently, European parliamentary systems entered a state of crisis as the rise of mass parties and revolutionary syndicalism destabilized the old liberal order. In France, the right-wing attempted multiple coups d' tat, while in Italy, tensions peaked with the massacre of protesters in Milan in $1898$ and the subsequent assassination of King Umberto I in $1900$. These events pushed the Italian nation to the brink of an authoritarian turn, signaling the fragility of the peace and progress so celebrated during the era.

Russian Autocracy and the Prelude to Revolution

The Russian Empire represented the most unstable and conflict-ridden reality of the East, still governed by an archaic tsarist autocracy devoid of parliamentary outlets. This rigid system spurred the growth of diverse opposition forces, including the Liberals of the Constitutional Democratic Party (known as the "Cadets"), who sought reforms modeled on the West, and the Social Revolutionaries, who utilized populist and sometimes terrorist methods to demand land redistribution for peasants. The Marxist movement formed the Russian Social Democratic Labour Party, which famously split during its $1903$ London congress into two factions: the Mensheviks, who favored a gradual democratic-bourgeois revolution, and the Bolsheviks, led by Lenin, who theorized a centralized vanguard of professional cadres to lead the proletariat directly toward a socialist revolution.

These internal pressures exploded following the disastrous Russo-Japanese War of $1904-1905$, a conflict over the control of Manchuria and Korea that ended in a humiliating naval defeat at Tsushima. The failure of the war esasperated the population, leading to the Revolution of $1905$. The breaking point was "Bloody Sunday" on $22$ January $1905$ in St. Petersburg, when the army opened fire on a peaceful procession led by a priest. This sparked a wave of strikes and mutinies across the empire, during which workers developed a new form of political organization: the soviets, or councils of elected delegates. To quell the uprising, Tsar Nicholas II was forced to grant a constitution and establish a parliament, the Duma. However, these were ephemeral concessions, as the regime soon returned to harsh restoration and failed agrarian reforms, leaving the autocracy in a state of unreformable stagnation.

Imperialist Rivalries and the Global Chessboard

International relations in the early twentieth century were dominated by an aggressive logic of power and global competition for colonial dominance, particularly in Africa and Asia. A prominent example was the Boer War in South Africa from $1899$ to $1902$, where the British clashed with Dutch-origin settlers over gold and diamond deposits, introducing dark practices such as civilian concentration camps. Meanwhile, Asia was also awakening; in $1912$, the millennia-old Chinese imperial system collapsed under a nationalist republican movement led by Sun Yat-sen, giving rise to the Republic of China. In Europe, the rise of Germany as a geopolitical powerhouse frightened Great Britain and France, leading to a realignment of alliances into two opposing blocs: the Triple Entente (France, Britain, and Russia) and the Triple Alliance (Germany, Austria-Hungary, and Italy).

The Balkan Peninsula became the "powder keg of Europe," where the decline of the Ottoman Empire sparked the expansionist appetites of Austria-Hungary and Russia. Austria’s annexation of Bosnia-Herzegovina in $1908$ deeply offended Serbia, which aspired to create a unified Slavic state under Russian protection. The situation further deteriorated with the Young Turk Revolution in Istanbul and Italy's attack on Libya in $1911$. These factors led to the two Balkan Wars of $1912-1913$, which resulted in a larger, more aggressive Serbia and a frustrated Austria-Hungary. This unstable landscape, combined with French revanchism over Alsace-Lorraine and Italian irredentist claims for Trento and Trieste, created the perfect conditions for a local incident to drag the entire continent into a global catastrophe.

The Giolittian Era and Italian Social Transformation

At the start of the century, Italy was a nation wounded by internal strife and the humiliating colonial defeat at Adwa in $1896$. The liberal ruling class was divided between the conservative approach of Sidney Sonnino, who wanted to strengthen executive power, and the reformist approach of Giovanni Giolitti, who dominated politics from $1901$ until the eve of the Great War. Giolitti’s fundamental intuition was to change the state's attitude toward labor conflicts by maintaining a position of absolute neutrality. He understood that allowing workers to fight for better wages would prevent violent revolutions and stimulate internal consumption, thereby aiding economic growth. Under his influence, significant social legislation was passed, including protections for female and child labor, mandatory accident insurance, and the nationalization of primary schools and railways.

Despite these advancements, a dualism persisted between the industrializing North and the stagnant South. In the Mezzogiorno, Giolitti relied on "special laws" and targeted investments rather than systemic reform, and the state often abandoned its neutrality to repress peasant struggles. This led to accusations of Giolitti having a "double face." Furthermore, his attempt to integrate the masses into the liberal state through an alliance with the Socialist Party, led by the reformist Filippo Turati, eventually failed due to the rise of revolutionary syndicalists. Consequently, Giolitti turned toward the Catholic world, leading to the first clandestine electoral agreements between liberals and Catholics. Simultaneously, a new threat emerged in the form of aggressive Nationalism, supported by intellectuals like D'Annunzio and the Futurist movement, which celebrated war as "the world's only hygiene."

The Outbreak of the First World War: A Sequence of Falling Dominos

The First World War was not merely a territorial dispute but a profound rupture in European civilization. Germany, as the youngest and most impetuous industrial power, felt excluded from the global colonial spoils and feared encirclement by older powers. Under Admiral Tirpitz, Germany initiated a massive naval arms race with Britain, using the rhetoric of war to suppress internal social conflicts. The spark for the conflagration occurred on $28$ June $1914$ in Sarajevo, when Archduke Franz Ferdinand was assassinated by the Serbian nationalist Gavrilo Princip. Though the event was localized, a rapid sequence of decisions by leaders Clark described as "sleepwalkers" led to an uncontrollable chain reaction of alliances: Austria declared war on Serbia on $28$ July, Russia mobilized, and Germany declared war on Russia and France, invading neutral Belgium on $4$ August to execute the Schlieffen Plan.

The initial illusion of a "lightning war" was shattered at the Battle of the Marne in September $1914$. By $1915$, the conflict had transformed into a stagnant war of position and attrition along a $650\,km$ front of trenches stretching from the North Sea to Switzerland. New technologies such as machine guns, heavy artillery, and asphyxiating gases (first used at Ypres in April $1915$) rendered traditional infantry charges obsolete, resulting in staggering causalities for virtually no territorial gain. On the Eastern Front, Germany halted Russian advances at Tannenberg and the Masurian Lakes, while the Ottoman Empire entered the war on the side of the Central Powers, leading to the failed Allied campaign at Gallipoli and the tragic Armenian Genocide, the first systematic extermination of the twentieth century, which claimed over $1$ million lives.

Italy’s Path to Intervention and the Great Turning Point of 1917

Italy initially declared neutrality in August $1914$, citing the defensive nature of the Triple Alliance and the nation's military unreadiness. However, the country became paralyzed by a split between Neutralists—including Giolittian liberals, Catholics under Pope Benedict XV, and Socialists—and Interventists, a vocal minority of nationalists, irredentists, and dissident socialists like Benito Mussolini. On $26$ April $1915$, the government secretly signed the Pact of London, committing Italy to join the Entente in exchange for territories like Trentino, South Tyrol, and Istria. This led to the "Radiant Days of May," where aggressive street protests forced the parliament to ratify the war. Italy entered the conflict on $24$ May $1915$, led by General Luigi Cadorna, who imposed a brutal discipline and a strategy of frontal assaults along the Isonzo River that yielded little success at a massive human cost.

The year $1917$ served as the conflict's pivot point. The Russian Empire collapsed due to internal revolution, allowing the Central Powers to focus their forces on the Western and Italian fronts. In Italy, this led to the disastrous retreat at Caporetto on $24$ October $1917$, where the army collapsed, and over $300.000$ men were taken prisoner. Cadorna was replaced by General Armando Diaz, who adopted a more humane leadership style, improving rations and morale. Concurrently, the United States entered the war in April $1917$, driven by Germany's unrestricted submarine warfare and the sinking of the Lusitania. This shifted the industrial and economic balance entirely toward the Allies. By $1918$, the Central Powers were exhausted; the Italian army triumphed at Vittorio Veneto, and Germany, facing internal revolution and an economic blockade, signed an armistice on $11$ November, ending the war.

The Fragile Peace and the Rise of the Soviet Union

The Paris Peace Conference of $1919$ was dominated by a "victors' peace" rather than the idealistic "Fourteen Points" proposed by U.S. President Woodrow Wilson. The Treaty of Versailles imposed a harsh "Diktat" on Germany, forcing it to accept full responsibility for the war, pay $132$ billion gold marks in reparations, and surrender significant territories. This created a lasting sense of humiliation that would later fuel Nazism. Meanwhile, the Austro-Hungarian, Ottoman, and Russian empires were dismantled, creating a fragmented map of new states like Czechoslovakia, Yugoslavia, and the Baltic Republics. In Italy, the failure to obtain Dalmatia and Fiume led to the myth of the "Mutilated Victory," causing deep resentment against the liberal government.

In Russia, the vacuum left by the Tsar was filled by the Revolution of $1917$. The February Revolution established a weak Provisional Government, but the Bolsheviks, led by Lenin, seized power in October with the promise of "Peace, Land, and Bread." Following a brutal Civil War against the "White" counter-revolutionaries and the implementation of "War Communism," the Bolsheviks emerged victorious. In $1922$, the Union of Soviet Socialist Republics (USSR) was officially formed. Lenin introduced the New Economic Policy (NEP) to restore the production of the war-torn country by allowing limited market elements. However, after Lenin's death in $1924$, a power struggle ensued between the internationalist Trotsky and Joseph Stalin, who advocated for "Socialism in One Country." Stalin eventually seized total control, launching a series of Five-Year Plans that prioritized heavy industry and forced the collectivization of agriculture, a process that led to the liquidation of the Kulaks and the devastating Holodomor famine in Ukraine.

The American Roaring Twenties and the 1929 Crisis

The United States emerged from the war as the new global hegemon, experiencing the "Roaring Twenties," a decade of unprecedented economic growth and mass consumption. The national income almost tripled between $1914$ and $1929$, driven by Taylorism and the assembly line methods of Henry Ford. Ford's "Five dollars a day" program transformed laborers into consumers, making cars and appliances accessible to the middle class. However, this era was also marked by deep contradictions, including the "Red Scare," a violent wave of xenophobia exemplified by the execution of Sacco and Vanzetti in $1927$, and the rise of the Ku Klux Klan, which reached $4$ million members in $1925$. Prohibition, introduced in $1920$, failed to moralize the country, instead empowering organized crime figures like Al Capone.

The system collapsed on "Black Thursday," $24$ October $1929$, with the Wall Street stock market crash. The crisis was caused by overproduction, a credit bubble, and agricultural stagnation that the liberal administration of Herbert Hoover could not address. The Great Depression saw the failure of over $5.000$ banks and a $50\%$ drop in industrial production. In $1932$, Franklin D. Roosevelt was elected on the promise of a "New Deal," which applied Keynesian theories of deficit spending to stimulate demand through massive public works like the Tennessee Valley Authority and social safety nets like the Social Security Act. The New Deal demonstrated that democratic systems could survive capitalist crises through state intervention, providing a distinct alternative to the rising totalitarian models in Europe.

The Ascent of Italian Fascism and the Nazi Totalitarian State

In Italy, the post-war crisis known as the "Biennio Rosso" ($1919-1920$) saw widespread strikes and factory occupations that terrified the bourgeoisie. Benito Mussolini transformed his marginal "Fasci di combattimento" into a mass movement by utilizing "squadrismo," or paramilitary violence, against socialists and unions. Following the March on Rome in October $1922$, King Victor Emmanuel III appointed Mussolini as Prime Minister. After the murder of the socialist deputy Giacomo Matteotti in $1924$ and the subsequent "Aventine Secession," Mussolini declared a dictatorship in a speech on $3$ January $1925$. The "Leggi Fascistissime" dismantled democracy, established the OVRA secret police, and eventually led to the Lateran Pacts of $1929$, reconcileing the state with the Catholic Church. The regime sought total control through the "fascistization" of society and pursued imperialist goals, culminating in the brutal conquest of Ethiopia in $1935-1936$ and the implementation of the Racial Laws in $1938$.

In Germany, the Weimar Republic was crippled by hyperinflation, which peaked in $1923$ with a dollar exchange rate of $4,2$ trillion marks. This misery paved the way for Adolf Hitler and the NSDAP. Hitler used the burning of the Reichstag in $1933$ as a pretext to declare a state of emergency and pass the Enabling Act, granting him absolute power. The Nazi state utilized the "Gleichschaltung" (alignment) to bring every institution under party control, while the Gestapo and SS maintained a climate of terror. The Nuremberg Laws of $1935$ stripped Jews of citizenship and prohibited mixed marriages, legalizing racial persecution. The "Kristallnacht" pogrom of November $1938$ signaled a transition to physical violence, as thousands of Jewish businesses were destroyed and over $20.000$ people were arrested, setting the stage for the systematic industrialization of death during the Second World War.

World War II and the Bipolar World Order

The Second World War was ignited by the German invasion of Poland on $1$ September $1939$. The conflict was a "total war" that saw the mobilization of entire populations and the implementation of the "Final Solution" at the Wannsee Conference in $1942$, leading to the genocide of $6$ million Jews in camps like Auschwitz-Birkenau. The war changed the global landscape; after the Allied victories at Stalingrad, Normandy, and the atomic bombings of Hiroshima and Nagasaki in $1945$, the world was divided into two spheres of influence. The Cold War emerged as a confrontation between the capitalist USA and the communist USSR, institutionalized through the Marshall Plan ($1947$), the NATO alliance ($1949$), and the Warsaw Pact ($1955$). Major flashpoints included the Korean War ($1950-1953$), the construction of the Berlin Wall in $1961$, and the Cuban Missile Crisis in $1962$, where the world neared nuclear annihilation.

Italian Reconstruction, Social Struggles, and Civil Rights

Post-war Italy transitioned to a Republic following the referendum of $2$ June $1946$, where women voted for the first time. The era was dominated by the Christian Democracy (DC) party and an economic boom that transformed the nation into an industrial power. However, the late $1960$s and $1970$s, known as the "Years of Lead," were marked by intense political violence from both the neo-fascist right and the far-left Red Brigades, culminating in the kidnapping and murder of Aldo Moro in $1978$. Despite this violence, the period saw landmark civil rights achievements, including the legalization of divorce ($1970$) and abortion ($1978$). The election of the Polish Pope John Paul II in $1978$ and the Soviet-Afghan war beginning in $1979$ further signaled the impending collapse of the Soviet system, which ultimately fell with the tearing down of the Berlin Wall on $9$ November $1989$, ending the bipolar era and signaling a new chapter in global history.

The Monopoly of Man and the Struggle for Gender Equality

The historical evolution of Italy and Europe cannot be fully understood without addressing the "monopoly of man," as described by Anna Kuliscioff in $1890$. She argued that the subjection of women was a social and cultural construct, with even the revolutionary male workers acting as domestic tyrants. The First World War proved to be a catalyst for change as women replaced men in the factories and fields, fostering a new self-awareness. Though the Fascist regime attempted to relegate women to the role of "angels of the hearth," the Resistance movement of $1943-1945$ saw women like Irma Bandiera and Carla Capponi serve as essential combatants and political organizers. The Italian Constitution of $1948$, shaped by mothers like Lina Merlin and Nilde Iotti, finally guaranteed legal equality. Today, however, the linguistic and economic remnants of this monopoly persist in debates over gender pay gaps and the representation of women in positions of power, reminding us that rights are a continuous historical relay rather than an end state.
