Civil Rights 19th Century North America

First African American Sworn into U.S. Congress

On February 25, 1870, Revels took the oath of office, becoming the first African American to serve in Congress.

U.S. Congress Creates Department of Justice

Following the Civil War, the United States faced challenges enforcing federal law across a vast territory amid Reconstruction and growing corporate power.

Grant signed legislation establishing the Department of Justice. The new agency centralized prosecution of federal crimes, civil litigation, and legal advice to the executive branch. It quickly took on cases involving Ku Klux Klan violence and interstate commerce.

Military 19th Century Europe

France Declares War on Prussia Igniting Franco-Prussian Conflict

Tensions had escalated in Europe following Prussia's victories in prior wars and its leadership in German unification efforts under Otto von Bismarck, challenging French dominance and influence over neighboring states. On July 19, 1870, Emperor Napoleon III of France formally declared war on Prussia after diplomatic provocations, including the manipulated Ems Dispatch, inflamed public opinion in both nations. French forces mobilized expecting a quick victory with superior rifles and mitrailleuse guns, but Prussian organization, railways, and artillery proved decisive from the outset. The declaration drew in other German states allied with Prussia, transforming a bilateral dispute into a broader continental war. Initial French setbacks quickly revealed the mismatch in military preparedness and strategy.

Napoleon III Surrenders at Battle of Sedan

The Franco-Prussian War erupted in July 1870 amid disputes over Spanish succession and Prussian influence in Europe. French forces under Emperor Napoleon III and Marshal MacMahon became trapped near the Belgian border after a series of defeats. On September 1, Prussian armies under Helmuth von Moltke completed the encirclement of Sedan, subjecting the French to devastating artillery fire from elevated positions. French cavalry charges proved futile against modern weaponry, and by afternoon Napoleon III ordered the white flag raised. Over 100,000 French troops surrendered the following day, including the emperor himself.

Politics 19th Century Europe

Napoleon III Deposed as Third Republic Proclaimed

News of the surrender reached Paris amid public outrage and fears of invasion. On September 4, republican deputies led by Léon Gambetta gathered at the Hôtel de Ville and proclaimed the Third Republic, ending the empire and establishing a provisional Government of National Defence. The move reflected widespread rejection of imperial rule following military collapse.

Italian Forces Capture Rome and Complete Unification

Following the proclamation of the Kingdom of Italy in 1861, Rome remained under papal control as the last major holdout of the Papal States, protected earlier by French troops.

On September 20, after a brief artillery bombardment that breached the Aurelian Walls near Porta Pia, Italian troops entered Rome. Papal forces offered limited resistance before surrendering. The event ended the temporal power of the papacy over Rome and allowed the city to become Italy's capital.
