TercioA Tercio (ˈteɾθjo), Spanish for "[a] third") was a military unit of the Spanish Army during the reign of the Catholic Monarchs and the Spanish Habsburgs in the early modern period. The Tercios were renowned as the finest professional infantry in Europe for over a century and a half due to their effectiveness of their battlefield formations. They were the elite military units of the Spanish Monarchy and the essential pieces of the powerful land forces of the Spanish Empire, sometimes also fighting with the navy.
Pike squareThe pike square (German: Gevierthaufen, lit. 'square crowd', or Gewalthaufen lit. 'crowd of force') was a military tactical formation in which 10 rows of men in 10 columns wielding pikes developed by the Swiss Confederacy during the 14th century for use by its infantry. The pike square was used to devastating effect at the Battle of Nancy against Charles the Bold of Burgundy in 1477, when the Swiss defeated a smaller but more powerful armored cavalry force.
Late Middle AgesThe Late Middle Ages, late medieval period, or Lower Middle Ages was the period of European history lasting from AD 1350 to 1500. The Late Middle Ages followed the High Middle Ages and preceded the onset of the early modern period (and in much of Europe, the Renaissance). Around 1350, centuries of prosperity and growth in Europe came to a halt. A series of famines and plagues, including the Great Famine of 1315–1317 and the Black Death, reduced the population to around half of what it had been before the calamities.
LandsknechtThe Landsknechte (singular: Landsknecht, ˈlantsknɛçt), also rendered as Landsknechts or Lansquenets, were Germanic mercenaries used in pike and shot formations during the early modern period. Consisting predominantly of pikemen and supporting foot soldiers, their front line was formed by Doppelsöldner ("double-pay men") renowned for their use of Zweihänder and arquebus. Originally organized by Emperor Maximilian I and Georg von Frundsberg, they formed the bulk of the Holy Roman Empire's Imperial Army from the late 1400s to the early 1600s, fighting in the Habsburg-Valois wars, the Habsburg-Ottoman wars, and the European wars of religion.
PhalanxThe phalanx (: phalanxes or phalanges) was a rectangular mass military formation, usually composed entirely of heavy infantry armed with spears, pikes, sarissas, or similar pole weapons. The term is particularly used to describe the use of this formation in ancient Greek warfare, although the ancient Greek writers used it to also describe any massed infantry formation, regardless of its equipment. Arrian uses the term in his Array against the Alans when he refers to his legions.
Battle of MarignanoThe Battle of Marignano was the last major engagement of the War of the League of Cambrai and took place on 13–14 September 1515, near the town now called Melegnano, 16 km southeast of Milan. It pitted the French army, composed of the best heavy cavalry and artillery in Europe, led by Francis I, newly crowned King of France, against the Old Swiss Confederacy, whose mercenaries until that point were regarded as the best medieval infantry force in Europe.
Battle of PaviaThe Battle of Pavia, fought on the morning of 24 February 1525, was the decisive engagement of the Italian War of 1521–1526 between the Kingdom of France and the Habsburg Empire of Charles V, Holy Roman Emperor as well as ruler of Spain, Austria, the Low Countries, and the Two Sicilies. The French army was led by King Francis I of France, who laid siege to the city of Pavia (then part of the Duchy of Milan within the Holy Roman Empire) in October 1524 with 26,200 troops.
Pike (weapon)A pike is a very long thrusting spear formerly used in European warfare from the Late Middle Ages and most of the early modern period, and were wielded by foot soldiers deployed in pike square formation, until it was largely replaced by bayonet-equipped muskets. The pike was particularly well known as the primary weapon of Swiss mercenary and German Landsknecht units. A similar weapon, the sarissa, had been used in antiquity by Alexander the Great's Macedonian phalanx infantry.
Huldrych ZwingliHuldrych or Ulrich Zwingli (1 January 1484 – 11 October 1531) was a leader of the Reformation in Switzerland, born during a time of emerging Swiss patriotism and increasing criticism of the Swiss mercenary system. He attended the University of Vienna and the University of Basel, a scholarly center of Renaissance humanism. He continued his studies while he served as a pastor in Glarus and later in Einsiedeln, where he was influenced by the writings of Erasmus.
Italian WarsThe Italian Wars, also known as the Habsburg–Valois Wars, were a series of conflicts fought between 1494 and 1559, mostly in the Italian peninsula, but later expanding into Flanders, the Rhineland and Mediterranean Sea. The primary belligerents were the Valois kings of France, and their Habsburg opponents in the Holy Roman Empire and Spain. At different points, various Italian states participated in the war, some on both sides, with limited involvement from England and the Ottoman Empire.
