Soldatenhandel

Last updated March 18, 2024

Soldatenhandel (German: 'soldier trade') was a practice of European states to raise and lease armed forces for compensation, especially in the German states of the Holy Roman Empire. It has been described as "military entrepreneurialism",^[1] where fiscal-military states provided "auxiliaries" or "subsidy armies" for wealthier, more powerful states and empires.^[2] The term especially refers to the practice following the end of the Thirty Years' War in 1648. The practice fell into disfavor during the 19th century.

Development

The use of auxiliaries dates to the Roman Empire.^[3] Auxilia, composed of non-citizens, were provided by provinces. After the collapse of the Western Roman Empire, Western Europe in the Early Middle Ages lacked a unifying imperial power. Although the Carolingian Empire is known to have used both militia levies and auxiliaries,^[4] other powers, such as the Eastern Roman Empire, preferred trained mercenary forces to untrained peasants.^[5]

Private mercenary groups played a significant military role in Medieval Europe, especially after the Kingdom of Germany was broken up.^[6] Mercenary forces provided the needed professional military units, but they could not be controlled by individual states.^[7] Even into the early modern period in Europe, warring states commonly hired armed forces as needed. It was estimated, for example, that 70% of France's forces were foreign-born in 1558, during the reign of Henry II of France.^[1] It was during that era that Black Bands and Landsknechts were organised as trained military forces that could defend the Holy Roman Empire or also become hired as mercenary forces.^[8]

The soldier trade grew during the Thirty Years' War (1618–1648) and the Franco-Spanish War (1635–1659).^[9] Ernst von Mansfeld, for example, was paid to defend the Bohemian Rebels. One of the most successful practitioners was Albrecht von Wallenstein, from Bohemia.^[10] The Thirty Years' War ended with the Peace of Westphalia, which introduced the principle of Westphalian sovereignty in which each state has exclusive control over its own territory. That was a significant step in the development of Soldatenhandel because smaller states could now raise their own armies and negotiate contracts with larger countries.^[2] The princes of the German states could establish mandatory service and offer cheaper prices than private mercenary contractors.^[10] That was a benefit to wealthier nations, which found such contracts cheaper than the maintenance of a large standing army.^[10]^[11] In the late 17th century, for example, France negotiated ready forces in Switzerland and Ireland.^[12]

Practice

The practice grew during the 17th and the 18th centuries. The Landgraviate of Hesse-Kassel, for example, leased soldiers to Denmark and Venice, supported William III of Orange in defending the Dutch Republic during his successful invasion of England in 1688, and it joined the Grand Alliance during the Nine Years' War.^[2] Hesse-Kassel had forces fighting on both sides of the War of the Austrian Succession.^[2] European legal experts such as Emer de Vattel argued that states could provide auxiliary forces to either side of a conflict without violating its neutrality.^[13] By the end of the 18th century, British Colonel William Fawcett wrote that it was no longer possible to recruit in Germany except with the permission of a state prince.^[14]

The primary motivation of the soldier trade is often viewed as financial. However, keeping an armed force trained and equipped came at a high cost and included financial risks. Fiscal-military states could not always obtain long-term contracts to financially maintain their armies.^[15] For instance, Württemberg and Bavaria failed to secure treaties with Great Britain during the American Revolutionary War because they had not been financially able to keep regiments in a state of readiness.^[10] Even when contracts were made, though, they rarely resulted in payments that covered all the expenses of a mobilized army and so states would normally lose money on their contracts.^[16] Furthermore, terms of payment were not always honoured.^[15]

States that did not participate in the soldier trade also faced financial risks, however. Members states that did not provide forces to the Holy Roman Empire could be made to pay a penalty.^[17]

Although the soldier trade rarely generated a profit, the use of armed forces was a key factor in establishing diplomatic ties. Smaller states established strong ties with imperial partners through the alliances established in their Soldatenhandel contracts.^[18] One illustration of this is 18th century Royal Deux-Ponts Regiment, which Palatine Zweibrücken maintained for the service of France, a powerful neighbour.^[19] States could also negotiate for diplomatic terms instead of money. Frederick I of Prussia, for example, earned the title of "King in Prussia" by a contract alliance with Leopold I, Holy Roman Emperor.^[20]

Great Britain, which fought the English Civil War near the end of the Thirty Years' War, did not keep a large standing army.^[21] Instead, it came to rely on the Soldatenhandel in the 18th century. Prime Minister Sir Robert Walpole paid Hesse-Kassel an annual fee to keep its army ready to be called up.^[2] William Pitt would later criticize that arrangement, but was forced to pay for the use of Soldatenhandel during the Seven Years' War.^[2] The numerous contracts that it funded throughout Europe during the era made Britain become known as the guarantor of the balance of powers.^[17] It again relied on Soldatenhandel during the American Revolutionary War by compensating six German states to fight in North America.

Recruitment

Peter H. Wilson describes four broad categories of recruitment during the era:

Direct recruitment involved the enlistment of men who resided in another jurisdiction to join an existing military unit.^[22]
Foreign regiments recruited men to form newly-established military units, either directly or through intermediaries.^[23]
Hired auxiliaries were whole military units provided by a foreign provider until the contract expired or until they were recalled by the foreign power.^[24] Auxiliary units could be fully dependent on the acquiring nation they served, or they could be subsidized and remain at least partially dependent on their own state.^[25]
Subsidy troops were partially funded by a state's ally but remained under control of their own state.^[26]

Most individual soldiers were recruited by their own state through conscription, mandatory service.^[27] When recruits volunteered, that was often contracted to pay off family debts.^[27]

Decline

Criticism of Soldatenhandel grew during the late 18th century. Playwrights such as Friedrich Schiller and Johann Krauseneck authored works with tragic characters forced to fight in the Americas.^[28] Johann Gottfried Seume wrote a fictionalised version of his voluntary enlistment in which Hessian officers captured him and sent him to Canada.^[29] The soldier trade had also become less profitable for the states supplying the military units. Karl, Prince of Brunswick-Wolfenbüttel, was almost ruined by his support of the British during the American Revolution.^[30] That may have influenced his new opinion that freeborn citizens could not be forced to take up arms except "to defend the fatherland".^[29]

The Napoleonic Wars saw the peak use of Soldatenhandel, but also saw its demise.^[31] Revolutionary ideas regarding nationalism and citizenship made it increasingly unpopular for rulers to send soldiers beyond their borders. In addition, as smaller states merged into the great powers of the late 19th century, the need for foreign auxiliary forces became less necessary.^[32] Increased mechanization during the industrial revolution made it easier to recruit within a nation's borders. Spain, Portugal, Naples, and the Papal States (and later Vatican City) were the last states to recruit significant numbers of foreign soldiers.^[33]

German historians in the 19th century were critical of Soldatenhandel and argued that the individual states' foreign alliances slowed the unification of the German nation.^[34] The practice was not widely studied and was often misunderstood by later historians.^[35]^[36]^[37] The United States, in particular, remains influenced by revolutionary-era descriptions of Hessian auxiliaries as "foreign Mercenaries" and "barbarous strangers".^[38] Recent scholarship suggests that Soldatenhandel was a necessary practice in early modern Europe for the small states providing military forces as well as for the larger kingdoms that were frequently drawn into wars.^[39]

An army, ground force or land force is an armed force that fights primarily on land. In the broadest sense, it is the land-based military branch, service branch or armed service of a nation or country. It may also include aviation assets by possessing an army aviation component. Within a national military force, the word army may also mean a field army.

The Thirty Years' War was one of the longest and most destructive conflicts in European history, lasting from 1618 to 1648. Fought primarily in Central Europe, an estimated 4.5 to 8 million soldiers and civilians died as a result of battle, famine, or disease, while parts of modern Germany reported population declines of over 50%. Related conflicts include the Eighty Years' War, the War of the Mantuan Succession, the Franco-Spanish War, the Torstenson War, the Dutch-Portuguese War, and the Portuguese Restoration War.

A mercenary, also called a merc, soldier of fortune, or hired gun, is a private individual who joins an armed conflict for personal profit, is otherwise an outsider to the conflict, and is not a member of any other official military. Mercenaries fight for money or other forms of payment rather than for political interests.

The Landgraviate of Hesse-Kassel, spelled Hesse-Cassel during its entire existence, also known as the Hessian Palatinate, was a state of the Holy Roman Empire. The state was created in 1567 when the Landgraviate of Hesse was divided upon the death of Philip I, Landgrave of Hesse. His eldest son William IV inherited the northern half of the Landgraviate and the capital of Kassel. The other sons received the Landgraviates of Hesse-Marburg, Hesse-Rheinfels and Hesse-Darmstadt.

Condottieri were Italian captains in command of mercenary companies during the Middle Ages and of multinational armies during the early modern period. They notably served popes and other European monarchs during the Italian Wars of the Renaissance and the European Wars of Religion. Notable condottieri include Prospero Colonna, Giovanni dalle Bande Nere, Cesare Borgia, the Marquis of Pescara, Andrea Doria, and the Duke of Parma.

Hessians were German soldiers who served as auxiliaries to the British Army during several major wars in the 18th century including the American Revolutionary War. The term is a synecdoche for all Germans who fought on the British side, since 65% came from the German states of Hesse-Kassel and Hesse-Hanau. Known for their discipline and martial prowess, around 30,000 Germans fought for the British during the war, around 25% of British land forces.

The Swiss mercenaries were a powerful infantry force constituted by professional soldiers originating from the cantons of the Old Swiss Confederacy. They were notable for their service in foreign armies, especially among the military forces of the kings of France, throughout the early modern period of European history, from the Late Middle Ages into the Renaissance. Their service as mercenaries was at its peak during the Renaissance, when their proven battlefield capabilities made them sought-after mercenary troops. There followed a period of decline, as technological and organizational advances counteracted the Swiss' advantages. Switzerland's military isolationism largely put an end to organized mercenary activity; the principal remnant of the practice is the Pontifical Swiss Guard at the Vatican.

Wilhelm Reichsfreiherr von Innhausen und Knyphausen was a German general officer who served in Hesse-Kassel. He fought in the American Revolutionary War, during which he commanded Hessian auxiliaries on behalf of Great Britain.

Irregular military is any non-standard military component that is distinct from a country's national armed forces. Being defined by exclusion, there is significant variance in what comes under the term. It can refer to the type of military organization, or to the type of tactics used. An irregular military organization is one which is not part of the regular army organization. Without standard military unit organization, various more general names are often used; such organizations may be called a troop, group, unit, column, band, or force. Irregulars are soldiers or warriors that are members of these organizations, or are members of special military units that employ irregular military tactics. This also applies to irregular infantry and irregular cavalry units.

Auxiliaries are support personnel that assist the military or police but are organised differently from regular forces. Auxiliary may be military volunteers undertaking support functions or performing certain duties such as garrison troops, usually on a part-time basis. Unlike a military reserve force, an auxiliary force does not necessarily have the same degree of training or ranking structure as regular soldiers, and it may or may not be integrated into a fighting force. Some auxiliaries, however, are militias composed of former active duty military personnel and actually have better training and combat experience than their regular counterparts.

The British Army came into being with the unification of the Kingdoms of England and Scotland into the Kingdom of Great Britain in 1707. The new British Army incorporated Regiments that had already existed in England and Scotland. The Army has traditionally relied on volunteer recruits, the only exceptions to this being during the latter part of the First World War until 1919, and then again during the Second World War when conscription was brought in during the war and stayed until 1960.

Colonial troops or colonial army refers to various military units recruited from, or used as garrison troops in, colonial territories.

The military of Carthage was one of the largest military forces in the ancient world. Although Carthage's navy was always its main military force, the army acquired a key role in the spread of Carthaginian power over the native peoples of northern Africa and southern Iberian Peninsula from the 6th century BC and the 3rd century BC. Carthage's military also allowed it to expand into Sardinia and the Balearic Islands. This expansion transformed the military from a body of citizen-soldiers into a multinational force composed of a combination of allies, citizens and foreign mercenary units.

Many of the small German states in Europe supported the British. King George III of Britain was simultaneously the ruler of the German state of Hanover. However some European Germans as individuals crossed the Atlantic to help the Patriots, who were supporters of Congress.

<span class="mw-page-title-main">Free company</span> Late medieval army of independent mercenaries

A free company was an army of mercenaries between the 12th and 14th centuries recruited by private employers during wars. They acted independently of any government, and were thus "free". They regularly made a living by plunder when they were not employed; in France they were called routiers and écorcheurs and operated outside the highly structured law of arms. The term "free company" is most often applied to those companies of soldiers which formed after the Peace of Brétigny during the Hundred Years' War and were active mainly in France, but it has been applied to other companies, such as the Catalan Company and companies that operated elsewhere, such as in Italy and the Holy Roman Empire.

The Treaty of Bärwalde, signed on 23 January 1631, was an agreement by France to provide Sweden financial support, following its intervention in the Thirty Years' War.

The Dutch States Army was the army of the Dutch Republic. It was usually called this, because it was formally the army of the States-General of the Netherlands, the sovereign power of that federal republic. This army was brought to such a size and state of readiness that it was able to hold its own against the armies of the major European powers of the extended 17th century, Habsburg Spain and the France of Louis XIV, despite the fact that these powers possessed far larger military resources than the Republic. It played a major role in the Eighty Years' War and in the wars of the Grand Alliance with France after 1672.

Imperial Army or Imperial Troops was a name used for several centuries, especially to describe soldiers recruited for the Holy Roman Emperor during the early modern period. The Imperial Army of the Emperor should not be confused with the Army of the Holy Roman Empire, which could only be deployed with the consent of the Imperial Diet. The Imperialists effectively became a standing army of troops under the Habsburg Emperors from the House of Austria, which is why they were also increasingly described in the 18th century as "Austrians", although its troops were recruited not just from the Archduchy of Austria but from all over the Holy Roman Empire.

Troops from Hesse-Hanau served as auxiliaries to the British Army during the American Revolutionary War, in accordance with the treaty of 1776 between Great Britain and the small principality. A regiment of foot, an artillery company, a ranger corp and a light infantry corp served in British America. A total of 2,422 soldiers were sent, with 1,441 returning, the remainder not surviving or choosing to remain in North America. As compensation, the reigning Count of Hesse-Hanau received a total of 343,110 pounds sterling from the British government.
