The Imperial Army (Latin: Exercitus Imperatoris), German: Kaiserliche Armee, Imperial Troops (Kaiserliche Truppen), or Imperials (Kaiserliche) for short, 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 (Exercitus Imperii (Romani), Reichsarmee, Armée du Saint-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 emperor 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
