Conscription in the context of "Barracks"

In modern scholarship, the "late" period of the Roman army begins with the accession of the Emperor Diocletian in AD 284, and ends in 480 with the death of Julius Nepos, being roughly coterminous with the Dominate. During the period 395–476, the army of the Roman Empire's western half progressively disintegrated, while its counterpart in the East, known as the East Roman army (or the early Byzantine army) remained largely intact in size and structure until the reign of Justinian I (r. AD 527–565).

The Imperial Roman army of the Principate (30 BC – 284 AD) underwent a significant transformation as a result of the chaotic 3rd century. Unlike the army of the Principate, the army of the 4th century was heavily dependent on conscription and its soldiers were paid much less than in the 2nd century. Barbarians from outside the empire probably supplied a much larger proportion of the late army's recruits than in the army of the 1st and 2nd centuries, but there is little evidence that this adversely affected the army's combat performance.

Japanese militarism (日本軍国主義, Nihon gunkoku shugi) was the ideology in the Empire of Japan which advocated the belief that militarism should dominate the political and social life of the nation, and the belief that the strength of the military is equal to the strength of a nation. It was most prominent from the start of conscription after the Meiji Restoration until the Japanese defeat in World War II, roughly 1873 to 1945. Since then, pacifism has been enshrined in the postwar Constitution of Japan as one of its key tenets.

A soldier is a person who is a member of an army. A soldier can be a conscripted or volunteer enlisted person, a non-commissioned officer, a warrant officer, or an officer.

The Battle of Manzikert or Malazgirt was fought between the Byzantine Empire and the Seljuk Empire on 26 August 1071 near Manzikert, Iberia (modern Malazgirt in Muş Province, Turkey). The decisive defeat of the Byzantine army and the capture of the emperor Romanos IV Diogenes played an important role in undermining Byzantine authority in Anatolia and Armenia, and allowed for the gradual Turkification of Anatolia. Many Turks, travelling westward during the 11th century, saw the victory at Manzikert as an entrance to Asia Minor.

The brunt of the battle was borne by the Byzantine army's professional soldiers from the eastern and western tagmata, as large numbers of mercenaries and Anatolian levies fled early and survived the battle. The fallout from Manzikert was disastrous for the Byzantines, resulting in civil conflicts and an economic crisis that severely weakened the Byzantine Empire's ability to defend its borders adequately. This led to the mass movement of Turks into central Anatolia – by 1080, an area of 78,000 square kilometres (30,000 sq mi) had been gained by the Seljuk Turks. It took three decades of internal strife before Alexius I (1081–1118) restored stability to Byzantium. Historian Thomas Asbridge says: "In 1071, the Seljuqs crushed an imperial army at the Battle of Manzikert (in eastern Asia Minor), and though historians no longer consider this to have been an utterly cataclysmic reversal for the Greeks, it still was a stinging setback." It was the only time a Byzantine emperor became the prisoner of a Muslim commander, and the first time since Valerian that a Roman emperor was captured alive by an enemy force.

The Gülhane Hatt-ı Şerifi ("Supreme Edict of Gülhane") or Tanzimât Fermânı ("Imperial Edict of Reorganization") was a proclamation by Ottoman Sultan Abdülmecid I in 1839 that launched the Tanzimât period of reforms and reorganization in the Ottoman Empire. It is named after Gülhane Park, where the edict was first proclaimed. The 125th anniversary of the edict was depicted on a former Turkish postcard stamp.

The proclamation was issued at the behest of reformist Grand Vizier Mustafa Reşid Pasha. It promised reforms such as the abolition of tax farming, reform of conscription, and guarantee of rights to all Ottoman citizens regardless of religion or ethnic group. The goal of the decree was to help modernize the empire militarily and socially so that it could compete with the Great Powers of Europe. It also was hoped the reforms would win over the disaffected parts of the empire, especially in the Ottoman controlled parts of Europe, which were largely Christian. At the time of the edict, millets (independent communal law-courts) had gained a large amount of religious autonomy within the empire, threatening the central government. This edict, along with the subsequent Imperial Reform Edict of 1856, was therefore an early step towards the empire's goal of Ottomanism, or a unified national and legal Ottoman identity. It was published in the Takvim-i Vekayi in Ottoman Turkish. In addition, it was published in Greek and French, the latter in Le Moniteur ottoman, and François Alphonse Belin, a dragoman, created his own French version, published in the Journal Asiatique.

A military oath, also known as the oath of enlistment or swearing-in is an oath delivered by a conscript or volunteer upon enlisting into the state's armed forces. Various states have different phrasings of the oath, with the common component being the fidelity to the state and obedience to the superior officers. In the ancient times it was a very solemn procedure. In modern times, with many formal laws and regulations to maintain army discipline, it is still a solemn, but rather a formal event.

Impressment, colloquially "the press" or the "press gang", is a type of conscription of people into a military force, especially a naval force, via intimidation and physical coercion, conducted by an organized group (hence "gang"). The navies of several European nations used various means of impressment starting in the late 16th century and continuing into the 19th century. The large size of the British Royal Navy in the Age of Sail meant that impressment was most commonly associated with Great Britain and Ireland. It was used by the Royal Navy in wartime, beginning in 1664 and during the 18th and early 19th centuries, as a means of crewing warships, although legal sanction for the practice can be traced back to the time of Edward I of England.

The Royal Navy impressed many merchant sailors, as well as some sailors from other, mostly European, nations. People liable to impressment were "eligible men of seafaring habits between the ages of 18 and 55 years". Non-seamen were sometimes impressed as well, though rarely. In addition to the Royal Navy's use of impressment, the British Army also experimented with impressment from 1778 to 1780.

A military reserve force is a military organization whose members (reservists) have military and civilian occupations. They are not normally kept under arms, and their main role is to be available when their military requires additional manpower. Reserve forces are generally considered part of a permanent standing body of armed forces, and allow a nation to reduce its peacetime military expenditures and maintain a force prepared for war. During peacetime, reservists typically serve part-time alongside a civilian job, although most reserve forces have a significant permanent full-time component as well. Reservists may be deployed for weeks or months-long missions during peacetime to support specific operations. During wartime, reservists may be kept in service for months or years at a time, although typically not for as long as active duty soldiers.

In countries with a volunteer military, reserve forces maintain military skills by training periodically (typically one weekend per month). They may do so as individuals or as members of standing reserve regiments—for example, the UK's Army Reserve. A militia, home guard, state guard or state military may constitute part of a military reserve force, such as the United States National Guard and the Norwegian, Swedish and Danish Home Guard. In some countries (including Colombia, Israel, Norway, Singapore, South Korea, Sweden, and Taiwan), reserve service is compulsory for a number of years after completing national service. In countries with conscription, such as Switzerland and Finland, reserve forces are citizens who have completed active duty military service but have not reached the upper age limit established by law. These citizens are subject to mandatory mobilization in wartime and short-term military training in peacetime.

The French Revolutionary Wars (French: Guerres de la Révolution française) were a series of sweeping military conflicts resulting from the French Revolution that lasted from 1792 until 1802. They pitted France against Great Britain, Austria, Prussia, Russia, and several other countries. The wars are divided into two periods: the War of the First Coalition (1792–1797) and the War of the Second Coalition (1798–1802). Initially confined to Europe, the fighting gradually assumed a global dimension. After a decade of constant warfare and aggressive diplomacy, France had conquered territories in the Italian peninsula, the Low Countries, and the Rhineland with its very large and powerful military which had been totally mobilized for war against most of Europe with mass conscription of the vast French population. French success in these conflicts ensured military occupation and the spread of revolutionary principles over much of Europe.

As early as 1791, the other monarchies of Europe looked with outrage at the revolution and its upheavals; and they considered whether they should intervene, either in support of King Louis XVI to prevent the spread of revolution, or to take advantage of the chaos in France. Austria stationed significant troops on its French border and together with Prussia issued the Declaration of Pillnitz, which threatened severe consequences should anything happen to King Louis XVI and Queen Marie Antoinette. After Austria refused to recall its troops from the French border and to back down on the perceived threat of using force, France declared war on Austria and Prussia in the spring of 1792; both countries responded with a coordinated invasion that was turned back at the Battle of Valmy in September. This victory emboldened the National Convention to abolish the monarchy. A series of victories by the French Revolutionary Army abruptly ended with defeat at Neerwinden in the spring of 1793. The French suffered additional defeats in the remainder of the year, and these difficult times allowed the Jacobins to rise to power and impose the Reign of Terror to unify the nation.
