Military history in the context of "Aztec warfare"

Theodore Ayrault Dodge (May 28, 1842 – October 26, 1909) was an American officer, military historian, and businessman. He fought as a Union officer in the American Civil War; as a writer, he was devoted to both the Civil War and the great generals of ancient and European history.

The military history of Mexico encompasses armed conflicts within that nation's territory, dating from before the arrival of Europeans in 1519 to the present era. Mexican military history is replete with small-scale revolts, foreign invasions, civil wars, indigenous uprisings, and coups d'état by disgruntled military leaders. Mexico's colonial-era military was not established until the eighteenth century. After the Spanish conquest of the Aztec Empire in the early sixteenth century, the Spanish crown did not establish on a standing military, but the crown responded to the external threat of a British invasion by creating a standing military for the first time following the Seven Years' War (1756–63). The regular army units and militias had a short history when in the early 19th century, the unstable situation in Spain with the Napoleonic invasion gave rise to an insurgency for independence, propelled by militarily untrained men fighting for the independence of Mexico. The Mexican War of Independence (1810–21) saw royalist and insurgent armies battling to a stalemate in 1820. That stalemate ended with the royalist military officer turned insurgent, Agustín de Iturbide persuading the guerrilla leader of the insurgency, Vicente Guerrero, to join in a unified movement for independence, forming the Army of the Three Guarantees. The royalist military had to decide whether to support newly independent Mexico. With the collapse of the Spanish state and the establishment of first a monarchy under Iturbide and then a republic, the state was a weak institution. The Roman Catholic Church and the military weathered independence better. Military men dominated Mexico's nineteenth-century history, most particularly General Antonio López de Santa Anna, under whom the Mexican military were defeated by Texas insurgents for independence in 1836 and then the U.S. invasion of Mexico (1846–48). With the overthrow of Santa Anna in 1855 and the installation of a government of political liberals, Mexico briefly had civilian heads of state. The Liberal Reforms that were instituted by Benito Juárez sought to curtail the power of the military and the church and wrote a new constitution in 1857 enshrining these principles. Conservatives comprised large landowners, the Catholic Church, and most of the regular army revolted against the Liberals, fighting a civil war. The Conservative military lost on the battlefield. But Conservatives sought another solution, supporting the French intervention in Mexico (1862–65). The Mexican army loyal to the liberal republic were unable to stop the French army's invasion, briefly halting it with a victory at Puebla on 5 May 1862. Mexican Conservatives supported the installation of Maximilian Hapsburg as Emperor of Mexico, propped up by the French and Mexican armies. With the military aid of the U.S. flowing to the republican government in exile of Juárez, the French withdrew its military supporting the monarchy and Maximilian was caught and executed. The Mexican army that emerged in the wake of the French Intervention was young and battle tested, not part of the military tradition dating to the colonial and early independence eras.

Liberal General Porfirio Díaz was part of the new Mexican military, a hero of the Mexican victory over the French on Cinco de Mayo 1862. He revolted against the civilian liberal government in 1876, and remained continuously in the presidency from 1880 to 1911. Over the course of his presidency, Díaz began professionalizing the army that had emerged. By the time he turned 80 years old in 1910, the Mexican military was an aging, largely ineffective fighting force. When revolts broke out in 1910–11 against his regime, a rebel forces scored decisive victories over the Federal Army in the opening chapter of the Mexican Revolution (1910–1920). Díaz resigned in May 1911, but Francisco I. Madero, on whose political behalf rebels rose against Díaz, demobilized the rebel forces and kept the Federal Army in place. "This single decision cost [Madero] the presidency and his life." Army General Victoriano Huerta seized the presidency of Madero in 1913, with Madero murdered in the coup d'état. Civil war broke out in the wake of the coup. Huerta's Federal Army racked up one defeat after another by the revolutionary armies, with Huerta resigning in 1914. The Federal Army ceased to exist. A new generation of fighting men, most of whom with no formal military training but were natural soldiers, now fought against each other in a civil war of the winners. The Constitutionalist Army under the civilian leadership of Venustiano Carranza and the military leadership of General Álvaro Obregón were the victors in 1915. The revolutionary military men were to continue to dominate Mexico's postrevolutionary period, but the military men who became presidents of Mexico brought the military under civilian control, systematically reining in the power of the military and professionalizing the force. The Mexican military has been under civilian government control with no President of Mexico being military generals since 1946. The fact of Mexico's civilian control of the military is in contrast the situation in many other countries in Latin America.

The Battle of Kursk, also called the Battle of the Kursk Salient, was a major World War II Eastern Front battle between the forces of Nazi Germany and the Soviet Union near Kursk in southwestern Russia during the summer of 1943, resulting in a Soviet victory. The Battle of Kursk is the single largest battle in the history of warfare. It ranks only behind the Battle of Stalingrad several months earlier as the most often-cited turning point in the European theatre of the war. It was one of the costliest battles of the Second World War, the single deadliest armoured battle in history, the largest tank battle in history, and the opening day of the battle, 5 July, was the single costliest day in the history of aerial warfare in terms of aircraft shot down. The battle was further marked by fierce house-to-house fighting and hand-to-hand combat.

The battle began with the launch of the German offensive Operation Citadel (German: Unternehmen Zitadelle), on 5 July, which had the objective of pinching off the Kursk salient with attacks on the base of the salient from north and south simultaneously. After the German offensive stalled on the northern side of the salient, on 12 July, the Soviets commenced their Kursk Strategic Offensive Operation with the launch of Operation Kutuzov (Russian: Кутузов) against the rear of the German forces on the same side. On the southern side, the Soviets also launched powerful counterattacks the same day, one of which led to a large armoured clash, the Battle of Prokhorovka. On 3 August, the Soviets began the second phase of the Kursk Strategic Offensive Operation with the launch of the Belgorod–Kharkov offensive operation (Operation Polkovodets Rumyantsev, Полководец Румянцев) against the German forces on the southern side of the salient.

The Battle of Stalingrad (17 July 1942 – 2 February 1943) was a major battle on the Eastern Front of World War II, beginning when Nazi Germany and its Axis allies attacked and became locked in a protracted struggle with the Soviet Union for control over the Soviet city of Stalingrad (now known as Volgograd) in southern Russia. The battle was characterized by fierce close-quarters combat and direct assaults on civilians in aerial raids; the battle epitomized urban warfare, and it was the single largest and costliest urban battle in military history. It was the bloodiest and fiercest battle of the entirety of World War II—and arguably in all of human history—as both sides suffered tremendous casualties amidst ferocious fighting in and around the city. The battle is commonly regarded as the turning point in the European theatre of World War II, as Germany's Oberkommando der Wehrmacht was forced to withdraw a considerable amount of military forces from other regions to replace losses on the Eastern Front. By the time the hostilities ended, the German 6th Army and 4th Panzer Army had been destroyed and Army Group B was routed. The Soviets' victory at Stalingrad shifted the Eastern Front's balance of power in their favour, while also boosting the morale of the Red Army.

Both sides placed great strategic importance on Stalingrad, for it was one of the largest industrial centres of the Soviet Union and an important transport hub on the Volga River: controlling Stalingrad meant gaining access to the oil fields of the Caucasus and having supreme authority over the Volga River. The city also held significant symbolic importance because it bore the name of Joseph Stalin, the leader of the Soviet Union. As the conflict progressed, Germany's fuel supplies dwindled and thus drove it to focus on moving deeper into Soviet territory and taking the country's oil fields at any cost. The German military first clashed with the Red Army's Stalingrad Front on the distant approaches to Stalingrad on 17 July. On 23 August, the 6th Army and elements of the 4th Panzer Army launched their offensive with support from intensive bombing raids by the Luftwaffe, which reduced much of the city to rubble. The battle soon degenerated into house-to-house fighting, which escalated drastically as both sides continued pouring reinforcements into the city. By mid-November, the Germans, at great cost, had pushed the Soviet defenders back into narrow zones along the Volga's west bank. However, winter set in and conditions became particularly brutal, with temperatures often dropping tens of degrees below freezing. In addition to fierce urban combat, brutal trench warfare was prevalent at Stalingrad.

Medieval warfare is the warfare of the Middle Ages. Technological, cultural, and social advancements had forced a severe transformation in the character of warfare from antiquity, changing military tactics and the role of cavalry and artillery (see military history). In terms of fortification, the Middle Ages saw the emergence of the castle in Europe, which then spread to the Holy Land (modern day Israel and Palestine).

Strategic studies is an interdisciplinary academic field centered on the study of peace and conflict strategies, often devoting special attention to the relationship between military history, international politics, geostrategy, international diplomacy, international economics, and military power. In the scope of the studies are also subjects such as the role of intelligence, diplomacy, and international cooperation for security and defense. The subject is normally taught at the post-graduate academic or professional, usually strategic-political and strategic-military levels.

Strategic studies is closely associated with grand strategy, which a state's strategy of how means (military and nonmilitary) can be used to advance and achieve national interests in the long-term.

The French invasion of Russia, also known as the Russian campaign, the Second Polish War, and in Russia as the Patriotic War of 1812, was initiated by Napoleon with the aim of compelling the Russian Empire to comply with the continental blockade of the United Kingdom. Widely studied, Napoleon's incursion into Russia remains a focal point in military history, recognized as among the most devastating military endeavors to ever unfold. In a span of fewer than six months, the campaign exacted a staggering toll, claiming the lives of nearly a million soldiers and civilians.

Beginning on 24 June 1812, the initial wave of the multinational Grande Armée crossed the Neman River, marking the entry from the Duchy of Warsaw into Russia. Employing extensive forced marches, Napoleon rapidly advanced his army of nearly half a million individuals through Western Russia, encompassing present-day Belarus, in a bid to dismantle the disparate Russian forces led by Barclay de Tolly and Pyotr Bagration totaling approximately 180,000–220,000 soldiers at that juncture. Despite losing half of his men within six weeks due to extreme weather conditions, diseases and scarcity of provisions, Napoleon emerged victorious in the Battle of Smolensk. However, the Russian Army, now commanded by Mikhail Kutuzov, opted for a strategic retreat, employing attrition warfare against Napoleon compelling the invaders to rely on an inadequate supply system, incapable of sustaining their vast army in the field.

Land warfare or ground warfare is the process of military operations eventuating in combat that takes place predominantly on the battlespace land surface of the planet.

Land warfare is categorized by the use of large numbers of combat personnel employing a diverse set of combat skills, methods and a wide variety of weapon systems and equipment, conducted in diverse terrains and weather environments. Land warfare, by virtue of being conducted in defence of urban and rural population areas, dominates the study of war, and is a focus for most national defence policy planning and financial considerations.
