Military history of Mexico

The military history of Mexico tells the story of many battles and changes from long ago until today. It began before Europeans arrived in 1519 and includes many fights and big wars.

In the early 1800s, Mexico fought for its independence from Spain. Leaders like Agustín de Iturbide and Vicente Guerrero helped create a new army called the Army of the Three Guarantees.

In the 1800s, Mexico faced many challenges, including fights with Texas and the United States. Generals like Antonio López de Santa Anna led the army but often faced defeats. Later, during a time called the Liberal Reforms, leaders tried to limit the power of the military. There was also a struggle when France tried to place its own ruler, Maximilian Hapsburg, as Emperor of Mexico. The Mexican army, led by people like Benito Juárez, fought back with help from the United States.

In the early 1900s, a big change happened with the Mexican Revolution. Leader Porfirio Díaz was overthrown, and new leaders took control. The military went through big changes, and by the mid-1900s, Mexico’s leaders made sure the military was under civilian control. This is different from many other countries in Latin America.

During World War II, Mexico was one of the Allies and sent troops to fight. More recent times have seen the Mexican military dealing with issues like keeping order and security along its borders.

Pre-Hispanic era, before 1519

Before Europeans arrived in 1492, many large civilizations lived in Mesoamerica. These groups sometimes fought each other for resources or power. Over time, small fights grew into bigger wars. The Aztec Empire, which formed in the 1400s, became very powerful and fought many wars.

The Maya people were once thought to live in peace, but we now know they had many wars too. There were fights between groups like Tikal and Calakmul in the Yucatán area. Other groups, like the Mixtecs and Zapotecs, also had their own smaller wars.

In the 1400s, the Aztecs fought many tribes. Some of these wars, called Flower wars, aimed to capture enemies alive. These captured people were used in special ceremonies for the Aztec gods.

The Aztecs sometimes worked as hired fighters in wars between other groups. Three cities — Tenochtitlan, Texcoco, and Tlacopan — joined together to form a strong alliance that ruled much of the area around Lake Texcoco.

The Chichimeca, nomadic groups living in northern Mexico, were never defeated by the Aztecs.

Spanish conquest of Mexico

Main article: Spanish conquest of the Aztec Empire

The Spanish conquest of the Aztec Empire happened from 1519 to 1521. It is one of the most famous events in history. It started when Spanish explorers arrived in the Caribbean in 1492. They wanted to explore new lands and find riches.

Hernán Cortés, a Spanish leader, landed on Mexico’s coast. He decided to go beyond the shoreline with a small group of men, horses, and weapons. He made friends with local groups who did not like Aztec rule, especially the people of Tlaxcala. These friends helped the Spanish fight against the Aztec Empire.

The Spanish also had help from Malinche. She spoke both the Aztec language and a Mayan language. She helped translate and give advice. Sadly, the Spanish brought diseases like smallpox. The Aztec people had never seen this disease before, and it made many very sick. After a long and hard battle, the Spanish and their allies defeated the Aztecs in 1521. This ended the Aztec rule.

Colonial-era control without a standing military

The Spanish did not have a regular army in Mexico until the 1700s. After they conquered parts of central Mexico in the 1500s, they gave land and control to leaders who helped them. These leaders kept the peace and helped people become Christians. Local leaders could carry weapons and ride horses, but ordinary people could not. Most local groups joined the Spanish empire peacefully, with only a few uprisings.

One big uprising happened in 1541 in what is now Jalisco, called the Mixtón war. It was stopped by Spanish soldiers and their allies. In northern Mexico, groups called Chichimeca became strong fighters against the Spanish after they got horses. They made it hard for the Spanish to settle there until silver was found in Zacatecas. Because silver was so valuable, the Spanish needed to protect the mines and paths used to move silver. This led to a long conflict called the Chichimeca War. The Spanish first built forts called presidios to keep guards there all the time. When that did not work well, they tried making peace and helping the local people become Christians. These efforts helped the Spanish control northern Mexico.

In the 1700s, other European countries, especially Britain, threatened Spain's control over its colonies, including Mexico. When Britain captured Havana in 1762, Spain decided to create a regular army to protect its colony.

Spain worried about giving weapons to many lower-class people, but they had to because there were too few Spanish people to defend the colony alone. They included mixed-race men in the army, though Indians were not required to serve. The new army also gave special privileges to wealthy local Spaniards, helping them gain status and recognition. This included the right to be tried in military courts for any crimes, which was meant to encourage their support and funding for the army.

Mexican War of Independence, 1810–1821

Main article: Mexican War of Independence

The Mexican War of Independence was a long fight from 1810 to 1821 to free Mexico from Spanish rule. Before this, people born in Mexico felt treated unfairly by leaders from Spain.

When Spain had problems during wars in Europe, some leaders in Mexico saw a chance to fight for their rights.

The war began when a priest named Miguel Hidalgo urged people to rise up against Spanish control. Many joined him, but the fight was hard. Leaders changed over time, and it wasn't until 1821 that Mexico finally won its independence.

First Mexican Empire and its overthrow, 1822–1823

Main article: Plan of Casa Mata

In 1821, Agustín de Iturbide, a former Spanish general, became emperor of Mexico after helping Mexico gain independence. He said this was only until a European royal could rule. But in 1823, a revolt led by Antonio López de Santa Anna and Guadalupe Victoria removed Iturbide and started the United Mexican States. In 1824, Guadalupe Victoria became the first president. He chose the name Guadalupe to honor Our Lady of Guadalupe.

The Plan of Casa Mata was made to end the monarchy and start a republic. It was signed by Santa Anna and Victoria in February 1823. The plan did not want an empire and asked for a new Congress. Soon, the plan was supported in places like Texas.

After Mexico won its independence from Spain, Spain wanted it back in the 1820s. A brave Mexican leader named Antonio López de Santa Anna became a hero by defending Mexico. During one battle, he lost a leg but kept fighting. Spain stopped trying to take Mexico back in 1836.

Pastry War, 1838

Main article: Pastry War

In 1838, a French baker in Mexico said Mexican soldiers had damaged his shop years before. France asked Mexico for money, but Mexico could not pay. This led France to send ships to block Mexican ports and attack a fort. Mexico and France were at war for a short time, but France left in 1839.

Texas Revolution, 1835–1836

Main article: Texas Revolution

Texas fought to become independent from Mexico between 1835 and 1836. There were important battles like the Alamo, where Mexican troops defeated the Texans, and the Battle of San Jacinto, where Texas won and created the Republic of Texas.

Main article: Mexican–American War

Mexico lost many lands to the United States during this war from 1846 to 1848. One famous battle was the Battle of Chapultepec in 1847, where young Mexican cadets fought very bravely. The war ended with Mexico giving up lands that are now part of the United States.

U.S. troops entered Mexico from many directions. They won several important battles and took over Mexico City. The war ended with treaties that let the United States take over new lands.

Caste War of Yucatán, 1847–1901

Main article: Caste War of Yucatán

The Maya people fought against others in the Yucatán Peninsula from 1847 to 1901. At one point, they pushed others out of most of the area, except for a few cities. The Maya had a special symbol called the "Talking Cross" that they believed gave them guidance. This war lasted for many years with fighting on both sides.

Era of the Liberal Reform

This time was not peaceful even though regular people controlled the government. There was a big fight inside Mexico called a civil war. Also, foreign soldiers from France tried to take over Mexico and put their own ruler in charge.

The Revolution of Ayutla in 1855 helped remove a leader named Santa Anna. Later, from 1857 to 1860, there was a war called the Reform War. Leaders tried to make new rules for everyone to be treated fairly, but this caused more fighting between different groups.

In 1862, France sent soldiers to Mexico while the United States was busy with its own civil war. Even though Mexican forces won an early battle on May 5 (now celebrated as Cinco de Mayo), the French kept fighting and put a new ruler named Maximilian in charge. After the U.S. civil war ended, the United States helped the Mexican leader Juárez. When French soldiers left, Maximilian was captured and removed from power. Juárez’s government returned, but another leader, Porfirio Díaz, later took control in 1876.

Porfiriato (1876–1911)

Main article: Porfiriato

From 1876 to 1911, a leader named Díaz controlled Mexico. He called this time the "Order and Progress" era. Díaz kept things calm so businesses would feel safe to help Mexico grow. He thought peace was important to get money from other countries.

Díaz made the army smaller because he was worried it might challenge him. Instead, he created a special group of rural police who worked for him. These police could travel fast on trains to places where people were unhappy, to help bring back peace. Building railways was a big project that helped Mexico develop during this time.

Mexican Revolution 1910–1920

Main article: Mexican Revolution

The Mexican Revolution was a long struggle in Mexico. It started in 1910 because people wanted change from the leader Porfirio Díaz, who had been in power for many years. The revolution lasted until 1920.

During this time, many brave people worked for change. Leaders like Venustiano Carranza, Emiliano Zapata, Pancho Villa, and Alvaro Obregón became important. They had different ideas about how Mexico should be run, which caused many battles.

Women also helped a lot during the revolution. Some fought with the soldiers, and they are remembered for their bravery. A brave woman named La Adelita became a famous symbol of this time.

While the revolution was happening, Mexico tried to stay neutral during World War I. There were some tense moments with the United States, but Mexico focused on its own fight for change.

Era of the Post Revolution, 1920–1946

In 1920, leaders from Sonora rebelled against the president. This began a time when military leaders held power. New leaders tried to reduce the military’s influence and bring it under central control. There were many failed uprisings, showing that power struggles continued.

One important event happened in 1920 when the president could not run for re-election. Instead of picking a loyal general, he chose a civilian. Some generals, including Alvaro Obregón, rebelled. The president had to flee, and Obregón became the new leader. Leaders worked to organize the military better and keep it out of politics. They made peace with figures like Pancho Villa by giving them land and money to stop fighting.

Later leaders kept working on these goals. They improved training for younger officers and reduced the military’s control over the government. Even with challenges, the military became more professional. During World War II, Mexico supported the Allies. Many people did not want to fight, but Mexico’s small air force unit joined the U.S. efforts in the Pacific. Many Mexican workers also traveled to the U.S. to help with the war effort.
