Mexican Army in the context of Secretary of War and Navy (Mexico)

The Thornton Affair was a battle in 1846 between the military forces of the United States and Mexico 20 miles (32 km) west upriver from Zachary Taylor's camp along the Rio Grande. The much larger Mexican force defeated the Americans in the opening of hostilities, and was the primary justification for U.S. President James K. Polk's call to Congress to declare war. It is also known as the Thornton Skirmish, Thornton's Defeat, or Rancho Carricitos.

The Mexican Armed Forces (Spanish: Fuerzas Armadas de México) are the military forces of the United Mexican States. The Spanish crown established a standing military in colonial Mexico in the eighteenth century. After Mexican independence in 1821, the military played an important political role, with army generals serving as heads of state. Following the collapse of the Federal Army during the 1910–1920 Mexican Revolution, former revolutionary generals systematically downsized the size and power of the military.

The Mexican military forces are composed of two independent entities: the Mexican Army and the Mexican Navy. The Mexican Army includes the Mexican Air Force, while the Mexican Navy includes the Naval Infantry Force (Marine Corps) and the Naval Aviation (FAN). The Army and Navy are controlled by two separate government departments, the National Defense Secretariat and the Naval Secretariat, and maintain two independent chains of command, with no joint command except the President of Mexico.

On 1 January 1994, the Zapatista Army of National Liberation (EZLN) coordinated a 12-day uprising in the state of Chiapas, Mexico, in protest against the enactment of the North American Free Trade Agreement (NAFTA). The rebels occupied cities and towns in Chiapas, releasing prisoners and destroying land records. After battles with the Mexican Army and police, a ceasefire was brokered on 12 January.

The revolt gathered international attention, and 100,000 people protested in Mexico City against the government's repression in Chiapas.

The Battle of Gonzales was the first military engagement of the Texas Revolution. It was fought near Gonzales, Texas, on October 2, 1835, between rebellious Texian settlers and a detachment of Mexican Army soldiers. In 1831, Green DeWitt asked the Mexican authorities to lend the Gonzales colonists a cannon to help protect them from frequent Comanche raids. One was supplied, on the condition that the cannon would be returned to the Mexicans on request. Over the next four years, the political situation in Mexico deteriorated, and in 1835 several states revolted. As the unrest spread, Colonel Domingo de Ugartechea, the commander of all Mexican troops in Texas, felt it unwise to leave the residents of Gonzales with a weapon and requested the return of the cannon.

When the initial request was refused, Ugartechea sent 100 dragoons to retrieve the cannon. The soldiers neared Gonzales on September 29, but the colonists used a variety of excuses to keep them from the town, while secretly sending messengers to request assistance from nearby communities. Within two days, up to 140 Texians gathered in Gonzales, all determined not to give up the cannon. On October 1, settlers voted to initiate a fight. Mexican soldiers opened fire as Texians approached their camp in the early hours of October 2. After several hours of desultory firing, the Mexican soldiers withdrew. Although the skirmish had little military significance, it marked a clear break between the colonists and the Mexican government and is considered to have been the start of the Texas Revolution. News of the skirmish spread throughout the United States, where it was often referred to as the "Lexington of Texas".

The Mexican Air Force (FAM; Spanish: Fuerza Aérea Mexicana) is the air service branch of the Mexican Armed Forces. It is a component of the Mexican Army and as such overseen by the National Defense Secretariat (SEDENA). The objective of the FAM is to defend the integrity, independence, and sovereignty of Mexico. Its auxiliary tasks include internal security, assisting with public works, and natural disaster management. As of 2024, its commander is Óscar René Rubio Sánchez.

The Mexican Secretariat of National Defense (SEDENA; Spanish: Secretaría de la Defensa Nacional) is the government department responsible for managing Mexico's Army and Air Forces. Its head is the Secretary of National Defense who, like the co-equal Secretary of the Navy, is directly answerable to the President. Before 1937, the position was called the Secretary of War and Navy (Secretaría de Guerra y Marina). The agency has its headquarters in Lomas de Sotelo, Miguel Hidalgo, Mexico City. Some key figures who answer directly to the Secretary are the Assistant Secretary, the Chief of Staff of the Armed Forces, and all military tribunals.

Alongside his role as a cabinet member the Secretary shares, since 2020, the official ex officio title of "Commanding General of the Mexican Army, Air Force, and National Guard" (Alto Mando del Ejercito, Fuerza Aerea, y Guardia Nacional).

The Goliad massacre was an event of the Texas Revolution that occurred on March 27, 1836, following the Battle of Refugio and the Battle of Coleto; 425–445 prisoners of war from the Texian Army of the Republic of Texas were executed by the Mexican Army in the town of Goliad, Texas. The men surrendered under the belief they would be set free within a few weeks; however, this was not to be. Despite appeals for clemency by General José de Urrea, the massacre was carried out by Lt. Colonel José Nicolás de la Portilla, under orders from General and President of Mexico Antonio Lopez de Santa Anna.

Ignacio Zaragoza Seguín (March 24, 1829 – September 8, 1862) was a Mexican Army officer and politician. He is best known for leading a Mexican army of 3,791 men which defeated a 5,730-strong force of French troops at the battle of Puebla on May 5, 1862 during the second French intervention in Mexico. The Mexican victory is celebrated annually as Cinco de Mayo.
