The Landsknechte were German 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. They formed the bulk of the Holy Roman Empire’s Imperial Army from the late 15th century to the early 17th century, fighting in the Habsburg-Valois wars, the Habsburg-Ottoman wars, and the European wars of religion.
