In addition to Cinco de Mayo and Mexican Independence day, there are numerous other dates throughout the year that can be used to commemorate events and educate others about Mexican life, history, and politics. This is a list of dates as they appear on the calendar, rather than the earliest to the most recent in chronological order. January 17, 1811: The Battle of Calderon Bridge Ramon Perez/Wikimedia Commons/Public Domain On January 17, 1811, a rebellious army of peasants and workers led by Father Miguel Hidalgo and Ignacio Allende fought a smaller but better equipped and better trained Spanish force at Calderon Bridge, outside of Guadalajara. The stunning defeat led to the capture and execution of Allende and Hidalgo but helped drag out Mexico's War of Independence for years. March 9, 1916: Pancho Villa Attacks the United States Bain Collection/Wikimedia Commons/Public Domain On March 9, 1916, the legendary Mexican bandit and warlord Pancho Villa led his army across the border and attacked the town of Columbus, New Mexico, hoping to secure money and weapons. Although the raid was a failure and led to an extensive U.S.-led manhunt for Villa, it greatly increased his reputation in Mexico. April 6, 1915: The Battle of Celaya Archivo General de la Nación/Wikimedia Commons/Public Domain On April 6, 1915, two titans of the Mexican Revolution collided outside of the town of Celaya. Alvaro Obregon got there first and dug himself in with his machine guns and trained infantry. Pancho Villa arrived not long after with a massive army including the best cavalry in the world at the time. Over the course of 10 days, these two fought it out and Obregon emerged the victor. Villa's loss marked the beginning of the end of his hopes for further conquest. April 10, 1919: Zapata Assassinated Mi General Zapata/Wikimedia Commons/Public Domain On April 10, 1919, rebel leader Emiliano Zapata, who had been the moral conscience of the Mexican Revolution fighting for land and freedom for the poorest Mexicans, was betrayed and assassinated in Chinameca. May 5, 1892: The Battle of Puebla Aurelio Escobar Castellanos/Wikimedia Commons/Public Domain The famous "Cinco de Mayo" celebrates an unlikely victory by Mexican forces over French invaders in 1862. The French, who had sent an army to Mexico to collect on a debt, were advancing on the city of Puebla. The French army was massive and well-trained, but heroic Mexicans—led in part by a dashing young General named Porfirio Diaz—stopped them in their tracks. May 20, 1520: The Temple Massacre Unknown/Wikimedia Commons/Public Domain In May of 1520, Spanish conquistadors had a tentative hold on Tenochtitlan, now called Mexico City. On May 20, Aztec nobles asked Pedro de Alvarado for permission to hold a traditional festival, which he granted. According to Alvarado, the Aztecs were planning a rebellion, and according to the Aztecs, Alvarado and his men simply wanted the golden jewelry they were wearing. In any case, Alvarado ordered his men to attack the festival, resulting in the slaughter of hundreds of unarmed Aztec nobles. June 23, 1914: The Battle of Zacatecas Unknown/Wikimedia Commons/Public Domain Surrounded by angry warlords, Mexican usurper President Victoriano Huerta sends his best troops to defend the city and railway junction at Zacatecas in a desperate effort to keep rebels out of the city. Ignoring orders from self-appointed rebel leader Venustiano Carranza, Pancho Villa attacks the town. Villa's resounding victory cleared the path to Mexico City and begins the downfall of Huerta. July 20, 1923: The Assassination of Pancho Villa Ruiz/Wikimedia Commons/Public Domain On July 20, 1923, legendary bandit warlord Pancho Villa was gunned down in the town of Parral. He had survived the Mexican Revolution and had been living quietly at his ranch. Even now, almost a century later, questions linger over who killed him and why. September 16, 1810: The Cry of Dolores Anonymous/Wikimedia Commons/Public Domain On September 16, 1810, Father Miguel Hidalgo took to the pulpit in the town of Dolores and announced that he was taking up arms against the hated Spanish—and invited his congregation to join him. His army swelled to hundreds, then thousands, and would carry this unlikely rebel to the gates of Mexico City itself. Ths "Cry of Dolores" marks Mexico's Independence Day. September 28, 1810: The Siege of Guanajuato Antonio Fabres/Wikimedia Commons/Public Domain Father Miguel Hidalgo's rag-tag rebel army was moving towards Mexico City, and the city of Guanajuato would be their first stop. Spanish soldiers and citizens barricaded themselves inside the massive royal granary. Although they defended themselves valiantly, Hidalgo's mob was too large, and when the granary was breached, the slaughter began. October 2, 1968: The Tlatelolco Massacre Marcel·li Perelló/Wikimedia Commons/Public Domain On October 2, 1968, thousands of Mexican civilians and students gathered in The Plaza of the Three Cultures in the district of Tlatelolco to protest repressive government policies. Inexplicably, security forces opened fire on the unarmed protestors, resulting in the death of hundreds of civilians, marking one of the lowest points in recent Mexican history. October 12, 1968: The 1968 Summer Olympics Sergio Rodriguez/Wikimedia Commons/Creative Commons 3.0 Not long after the tragic Tlatelolco Massacre, Mexico hosted the 1968 Summer Olympics. These games would be remembered for Czechoslovakian gymnast Věra Čáslavská being robbed of gold medals by Soviet judges, Bob Beamon's record long jump, and American athletes giving the Black power salute. October 30, 1810: The Battle of Monte de las Cruces Ramon Perez/Wikimedia Commons/Public Domain As Miguel Hidalgo, Ignacio Allende and their rebel army marched on Mexico City, Spanish in the capital were terrified. Spanish Viceroy Francisco Xavier Venegas rounded up all available soldiers and sent them to delay the rebels as best they could. The two armies clashed at Monte de Las Cruces on October 30, and it was another resounding victory for the rebels. November 20, 1910: The Mexican Revolution Wikimedia Commons/Public Domain Mexico's 1910 elections was a sham designed to keep long-term dictator Porfirio Diaz in power. Francisco I. Madero "lost" the election, but he was far from through. He went to the United States, where he called on Mexicans to rise up and overthrow Diaz. The date he gave for the beginning of the revolution was November 20, 1910. Madero could not foresee the years of strife that would follow and claim the lives of hundreds of thousands of Mexicans—including his own.
