Condottieri: mercenaries of the Italian republics

For roughly two centuries, from the 1300s to the 1500s, most wars in the Italian peninsula were not fought by citizen armies but by military contractors hired on paper. They are known as condottieri, after the condotta: the contract that set out how many men a captain supplied, for how long, for how much money, and under what obligations. Understanding that system explains how Florence, Venice, Milan and the Papal States waged war for generations without mobilising their own populations.

This was not an Italian oddity. It was the local shape of a wider European market in professional soldiers: companies left idle by truces in the Hundred Years' War crossed the Alps and sold their services to the highest bidder. On that foundation grew a contractual military industry, studied in depth by Michael Mallett and, through Florentine account books, by William Caferro.

Why Italian republics hired instead of conscripting

The Italian city-states were wealthy, densely populated and commercially advanced, but politically brittle. Arming their own citizens carried an obvious risk: a strong urban militia could tip internal factional struggles. Hiring outside force solved three problems at once. It provided experienced troops without pulling workers out of trade and manufacture, it turned war into a financial problem that Florentine and Venetian public debt could handle, and it kept armed power outside domestic politics.

The price was dependence. A captain with his own following, castles and credit could bargain as an equal, walk away when the contract lapsed, or become a ruler himself. Milan is the extreme case: Francesco Sforza, hired as a captain, ended up governing the city as duke in 1450.

The condotta was a real contract, not a handshake

A condotta was a detailed legal document registered by the hiring state's chancery. It named the number of lances, horses and foot soldiers, the term of service — usually a firm period followed by an optional extension — the payment schedule, the division of plunder and ransoms, and rules for muster and inspection. States sent commissioners to count horses and men, because inflating troop numbers was the standard fraud.

Free companies and the captains who mattered

Before large state contracts became routine, the field belonged to the free companies: self-governing armed bands that lived off war and, in peacetime, off systematic extortion of towns and countryside. Werner von Urslingen's Great Company and, above all, the White Company where the Englishman John Hawkwood learned his trade are the best-documented examples. Caferro traced in Florentine accounts how Hawkwood moved from external threat to captain-general in Florentine service, with salary, property and an honorific tomb in the cathedral.

• John Hawkwood (c. 1323-1394): English captain of the White Company, later commander for Florence.
• Francesco Sforza (1401-1466): contractor turned Duke of Milan, the clearest case of political ascent.
• Bartolomeo Colleoni (c. 1400-1475): captain-general of Venice, remembered through Verrocchio's equestrian monument.
• Federico da Montefeltro (1422-1482): lord of Urbino, military contractor and leading Renaissance patron.

Machiavelli and the bloodless-battle myth

The image of the condottiero as a self-serving and unreliable soldier owes much to Machiavelli, who argued in chapters XII and XIII of The Prince that mercenary and auxiliary troops are useless and dangerous, and that a state needs its own army. That was a political argument written after Italy's collapse before French and Spanish armies, not a neutral description of how the system worked.

From it grew a nineteenth-century commonplace, popularised through readings such as Jacob Burckhardt's: that condottieri fought nearly bloodless battles to preserve their working capital. Later scholarship has dismantled that view. Mallett and Caferro document hard campaigns, long sieges, sacked towns and real mortality; Anghiari in 1440, sometimes cited as a battle without deaths, in fact left casualties and prisoners in the record. What did exist was an economic logic favouring capture over killing: a prisoner was worth a ransom, and an intact company was worth the next contract.

Decline: when contracts stopped being enough

The system faded as the scale of war changed. The Italian Wars that began in 1494 with Charles VIII's invasion pitted city-states against monarchies able to field large standing armies, massed artillery and disciplined pike infantry. Seasonal contract companies were structurally outmatched. Venice and the papacy kept hiring captains, but increasingly inside permanent military administrations with regular pay, quarters and inspection — the road to the modern standing army.
