Iraq Gains Independence from British Mandate

Following the dissolution of the Ottoman Empire after World War I, Britain administered Iraq under a League of Nations mandate established in 1920. King Faisal I and Iraqi leaders negotiated terms for sovereignty while Britain maintained strategic interests including military bases. On October 3, 1932, Iraq was admitted to the League of Nations as an independent kingdom, formally ending the mandate. The transition occurred after years of local uprisings and diplomatic maneuvering. Britain retained influence through treaties, but the date symbolized the first Arab state to achieve recognized independence in the interwar period. Faisal's government assumed full internal responsibilities.

Reichstag Fire Destroys German Parliament Building

In the tense political climate following Adolf Hitler’s appointment as chancellor earlier that month, the Reichstag building in Berlin caught fire on the evening of February 27, 1933. A young Dutch communist named Marinus van der Lubbe was arrested at the scene and later executed after confessing, though historians debate whether he acted alone or whether the Nazis themselves orchestrated the blaze. Hitler’s government immediately blamed communists, using the incident to suspend civil liberties through the Reichstag Fire Decree and arrest thousands of political opponents. The event accelerated the Nazi consolidation of power just weeks before the March elections.

The United States faced the depths of the Great Depression in early 1933, with widespread bank failures, unemployment exceeding 25 percent, and economic paralysis gripping the nation. Franklin D.

Nazi Germany Outlaws All Other Political Parties

After Adolf Hitler became chancellor in January 1933, the Nazi regime moved swiftly to consolidate power through emergency decrees and intimidation. The Reichstag fire provided pretext for suspending civil liberties and arresting communists and other opponents. On July 14, 1933, a decree formally dissolved all remaining political parties except the National Socialist German Workers' Party, completing the Gleichschaltung process of coordination. Opposition leaders were imprisoned, exiled, or forced underground. This left the Nazis with a monopoly on political organization in Germany.

United States Establishes Relations with Soviet Union

Following the 1917 Bolshevik Revolution, the United States had refused to recognize the Soviet government, citing ideological opposition and unpaid tsarist debts. By 1933, amid the Great Depression and rising threats from Nazi Germany and Imperial Japan, President Franklin D. Roosevelt sought to expand trade opportunities and counterbalance emerging powers. On November 16, 1933, the U.S. and USSR formally established diplomatic relations through an exchange of notes between Roosevelt and Soviet Foreign Minister Maxim Litvinov. The agreement included Soviet promises regarding religious freedoms for Americans in the USSR and settlement of certain financial claims. This step normalized ties after 16 years of non-recognition and opened avenues for economic and strategic cooperation.

Twenty-First Amendment Ends National Prohibition

The Eighteenth Amendment had banned the manufacture, sale, and transportation of alcohol across the United States since 1920, fueling organized crime, speakeasies, and widespread public discontent during the Roaring Twenties and Great Depression. In February 1933 Congress proposed the Twenty-First Amendment to repeal the ban, uniquely requiring ratification by state conventions rather than legislatures. On December 5 Utah became the thirty-sixth state to approve it, meeting the three-fourths threshold; Pennsylvania and Ohio had ratified earlier that day. Acting Secretary of State William Phillips certified the amendment at approximately 5:32 p.m. EST, and President Franklin D. Roosevelt quickly issued a proclamation ending national Prohibition. The repeal immediately allowed legal alcohol sales in most states and generated new tax revenue while diminishing...

Hitler Becomes Führer of Germany

Following the death of President Paul von Hindenburg on August 2, 1934, Chancellor Adolf Hitler moved swiftly to consolidate power in the Weimar Republic's final days. The German cabinet had already passed a law merging the offices of president and chancellor, and the army swore an oath of personal loyalty to Hitler. This transition eliminated the last constitutional checks on his authority after the Enabling Act of 1933. Nazi propaganda framed the change as a natural evolution toward unified leadership. Within weeks, a plebiscite confirmed the new structure with overwhelming approval under controlled conditions. The event marked the formal establishment of the Führer state.

February 26 Incident: Japanese Military Coup Attempt

In 1930s Japan, factional rivalries within the Imperial Japanese Army pitted radical young officers influenced by ultranationalist and agrarian reform ideas against more moderate senior leaders. Economic hardships and political instability fueled discontent among junior officers who sought to purge perceived corrupt or Western-influenced elements from the government.
