Military history
The confrontation between Upper and Lower Egypt around 3150 BC marks the earliest documented conflicts in human history. Military scribe Tjaneni recorded the Battle of Megiddo in the 15th century BC, which stands as the first battle described with relatively reliable detail. Sumerian city-states like Lagash and Umma fought over the fertile Guedena region for several generations, creating one of the earliest known wars. The Umma, Lagash war lasted across multiple generations, establishing a pattern of border conflict that would define early statehood. Heroic epics such as the Epic of Gilgamesh and Homer's Iliad contain abundant military details, though their historicity remains debated by scholars. Herodotus wrote The Histories between 484 and 425 BC, earning him the title father of history through his systematic approach to recording events. Thucydides composed The Peloponnesian War while exiled from Athens, allowing him to examine documents and interview eyewitnesses from opposing sides. Xenophon documented the expedition of Cyrus the Younger into Anatolia in Anabasis, providing a leader-centered analysis of ancient campaigns. Roman historians including Livy, Appian, and Cassius Dio chronicled Rome's rise to Mediterranean dominance through detailed accounts of battles and political struggles. Julius Caesar's Commentarii de Bello Gallico offered a comparative perspective on campaigns that shaped European history. Chinese strategic doctrines appeared in texts like Arthashastra in India and The Art of War in China during the Axial Age. Sima Qian recorded the Warring States period and the Qin unification wars in the Grand Historian, preserving records of conflicts spanning centuries.
Chariots originated around 2000 BC and became crucial weapons for maintaining governments across the New Egyptian Kingdom and Shang dynasty. A chariot required two men: one controlled maneuvering while a second bowman shot arrows at enemy soldiers. Infantry formed the core of military action for settled agrarian civilizations, evolving from opposing armed groups under commanders into rigid phalanxes used by Greeks and early Romans. Macedonian Alexander the Great deployed cavalry forces effectively to secure victories across Asia. Parthians, Scythians, Mongols, and other steppe people developed horse archery tactics that allowed shooting while riding. War elephants were first used in India and later adopted by Persians, appearing in the Battle of the Hydaspes River and Hannibal's Second Punic War against Rome. Naval warfare began with sailing ships without cannons, often using human oar power built up to ramming speed. Galleys were employed by Cretans in the 3rd millennium BC before Greeks advanced these designs. The first recorded naval battle occurred in 1210 BC between Suppiluliuma II, king of the Hittites, and Cyprus. Themistocles helped build a Greek navy composed of 310 ships that defeated Persians at the Battle of Salamis in 480 BC. Gunpowder evolved slowly from Chinese alchemists as early as the 4th century, initially used for life force experiments before becoming pyrotechnics and incendiaries. Cannons appeared in Europe in the early 14th century, playing vital roles in the Hundred Years' War. By 1346, cannons had been used at the Battle of Crécy, and again at Agincourt. Matchlock firearms emerged in the mid-15th century, allowing guns to be aimed and fired while held steady with both hands. Francis Drake successfully used fire ships to scatter the Spanish Armada at the Battle of Gravelines. Naval mines were invented in the 17th century but not used heavily until the American Civil War. The first navigable submarine was built in 1624 by Cornelius Drebbel, cruising at depths of 15 feet. Chemical warfare exploded into public consciousness during World War I when Germans used gas-filled shells at the Battle of Bolimov in January 1915. The atomic bomb developed by the Manhattan Project ended World War II when dropped on Hiroshima and Nagasaki in 1945.
Michael Roberts introduced the concept of military revolution in the 1950s, focusing on Sweden between 1560 and 1660 as his primary case study. Roberts emphasized muskets that could not aim at small targets but proved effective when fired in volleys by three ranks of infantry soldiers. One rank fired while the other two reloaded, then all three marched forward to demolish enemy positions. Infantry gained firepower previously reserved for artillery while maintaining mobility that artillery lacked on battlefields. These tactical innovations required permanent standing armies rather than temporary feudal levies or mercenaries. Armies grew much larger and more expensive, creating new financial demands and governmental institutions. Geoffrey Parker modified the concept in the 1990s, arguing that developments in fortification and siege warfare caused the revolution instead. Technology played a minor role compared to organization, command and control, logistics, and non-material improvements. Noted historians Michael Duffy and Jeremy Black strongly criticized the theory as misleading, exaggerated, and simplistic. The revolutionary nature of these changes only became visible after long evolution that handed Europe predominant place in warfare. Industrial warfare later confirmed this position through technological advances that transformed how nations fought. The Dutch and Swedish reforms between 1560 and 1660 led to needs for better trained troops and administrative support. Modern states emerged partly because the art of war made their creation necessary for sustaining large professional forces. Military historians continue debating whether technology drove change or if organizational shifts mattered more.
Countries began abandoning complete reliance on professional soldiers in favor of conscription as weapons became easier to use during industrial warfare. Napoleon Bonaparte notably employed conscription to increase military personnel available for combat across European campaigns. William Tecumseh Sherman's March to the Sea and Philip Sheridan's burning of the Shenandoah Valley exemplified total war strategies during the American Civil War. Strategic bombing of enemy cities and industrial factories reached its largest scale during World War II as part of total warfare objectives. The Battle of Sadowa demonstrated how possession of advanced technology could decisively determine outcomes in industrial age conflicts. Conscription allowed nations to field massive armies capable of sustained operations against well-equipped opponents. The Franco-Prussian War showcased how technological superiority could shift balance even when numbers favored one side. Modern tanks featured composite armor, high caliber cannons, and advanced targeting systems developed during the Cold War era. Nuclear submarines invented in 1955 no longer needed frequent surfacing and ran quietly while serving as underwater missile platforms. These developments completed what became known as nuclear triad capabilities among major world powers. The Space race between United States and Soviet Union involved launching human beings into space and sending satellites to orbit. Intelligence gathering evolved through spy satellites and ballistic missiles that changed how nations prepared for potential conflicts.
Since 1945, actual fighting has largely become civil wars and insurgencies rather than interstate conflicts between sovereign states. Preparation for major wars shifted toward technological arms races involving nuclear weapons, biological agents, computerized control systems, and new operational venues like space. The Indo-Pakistani War of 1971, Iran-Iraq War from 1980 to 1988, Gulf War of 1990-91, and Russo-Ukrainian War stand as exceptions to declining interstate warfare trends. Civil conflicts and irregular warfare have replaced traditional state-to-state combat as the dominant form of armed conflict since mid-century. The decline in number and casualties of conventional wars contrasts sharply with persistent internal struggles within nations. Modern warfighting entities operate beyond neo-medieval frameworks, challenging established concepts of sovereignty and territorial integrity. Computerized control systems now manage complex operations across multiple domains simultaneously. Nuclear and biological weapons remain central concerns for national security planning despite international treaties attempting to limit their use. The opening of new venues like cyberspace and orbital platforms has expanded where conflicts can occur beyond traditional battlefields.
William H. McNeill described military history as flourishing in an intellectual ghetto despite enormous popularity with general public readers. The 144 books published between 1968 and 1978 fell into two distinct classes: works aimed at popular readership written by journalists outside academic circles, and professional work produced within military establishments. University level courses in military history remained seriously underdeveloped throughout much of the 20th century. Lack of interest and disdain for military history constituted one of the strangest prejudices of the history profession according to scholars. Eugene P. A. Scleh explored teaching a course called Modern War and Its Images entirely through films at the University of Maine. Students found documentaries more valuable than dramas when studying combat experiences. Jeremy Black outlined problems facing 21st-century military historians including Eurocentricity, technological bias, focus on leading powers, separation of land from sea and air conflicts, and lack of attention to political tasking. Scholars still do not know exact nature of Greek fire due to destroyed or unrecorded evidence valued as military secrets. Researching Operation Enduring Freedom and Operation Iraqi Freedom presented unique challenges because records were destroyed to protect classified information. Jeffrey Kimball surveyed ideological preferences of 109 active diplomatic historians and 54 active military historians in United States during early 1980s. He found current political views moderately correlated with historiographical interpretations regarding causes of 20th century wars. Military historians maintain their own scholarly organization called Society for Military History which has published The Journal of Military History since 1937.
