Great Molasses Flood Devastates Boston

In Boston's North End, a massive steel tank belonging to the United States Industrial Alcohol Company held over two million gallons of molasses used in rum production and industrial processes. On the afternoon of January 15, 1919, a sudden temperature rise after cold weather caused the poorly constructed tank to rupture, releasing a wave of sticky liquid up to 25 feet high that traveled at speeds exceeding 30 miles per hour through city streets. The flood killed 21 people, injured dozens more, and caused extensive property damage as it swept away buildings, horses, and vehicles before the molasses cooled and hardened.

Post-World War I Italy faced economic turmoil, social unrest, and disillusionment among veterans. Benito Mussolini, a former socialist editor who broke with the left, called for a new nationalist movement. On March 23, 1919, he established the Fasci Italiani di Combattimento in Milan with around 200 attendees including war veterans and nationalists. The group advocated aggressive Italian expansion, anti-socialism, and paramilitary action. It served as the foundation for the National Fascist Party formed in 1921 and Mussolini's eventual rise to power.

Mexican Revolutionary Emiliano Zapata Killed in Ambush

During the Mexican Revolution that began in 1910, Emiliano Zapata emerged as a key leader in Morelos state, championing land reform and peasant rights against large landowners and the federal government under Porfirio Díaz and later successors.

On April 10, he was lured into a trap by government forces in Chinameca, Morelos, where he was ambushed and shot dead along with several aides. The assassination was part of efforts by President Venustiano Carranza to eliminate opposition leaders. Zapata's death was widely mourned among rural populations.

Weimar Constitution Signed into Law in Germany

Following Germany's defeat in World War I and the abdication of Kaiser Wilhelm II, a national assembly convened in Weimar to draft a new republican framework amid political instability and economic hardship. On July 31, 1919, the assembly approved the constitution, which Friedrich Ebert, the provisional president, signed on August 11. The document established a federal parliamentary democracy with a president, chancellor, and Reichstag, incorporating progressive elements like universal suffrage and social welfare provisions. It took effect on August 14, formally ending the provisional government and creating the Weimar Republic. This legal foundation aimed to stabilize the nation but faced immediate challenges from extremists on both sides.

President Wilson Suffers Debilitating Stroke

Woodrow Wilson had returned from the Paris Peace Conference determined to secure U.S. ratification of the Treaty of Versailles and membership in the League of Nations. Exhaustion from an intense cross-country speaking tour to build public support left him vulnerable. On October 2, 1919, Wilson suffered a severe ischemic stroke at the White House that paralyzed his left side and impaired his cognitive functions. His wife Edith and physician Cary Grayson tightly controlled access to the president, shielding the extent of his incapacity from the public and Congress for months. The stroke effectively sidelined Wilson during critical debates over the treaty.

Congress Overrides Wilson Veto of Volstead Act

The Eighteenth Amendment, ratified earlier in 1919, banned the manufacture, sale, and transportation of intoxicating liquors. To enforce it, Congress crafted the National Prohibition Act, known as the Volstead Act after its sponsor. President Woodrow Wilson vetoed the measure on October 27, citing wartime and economic concerns. On October 28, both the House and Senate overrode the veto with the required two-thirds majorities, enacting the law. The legislation defined enforcement mechanisms, penalties, and exceptions for industrial and medicinal uses while empowering federal agents. It took effect in January 1920, launching the Prohibition era.
