The Army of the Holy Roman Empire (French: Armée du Saint-Empire; German: Reichsarmee, Reichsheer, or Reichsarmatur; Latin: Exercitus Imperii) was created in 1422 and came to an end when the Holy Roman Empire was dissolved in 1806 as a result of the Napoleonic Wars.

In practice, the various forces of the Army of the Empire often had stronger local allegiances than to the Holy Roman Emperor.

Over the next hundred years, the size of the Army was controlled either by the number of serving men being strictly regulated or by limits on the money that paid for it.

[4] Contrary to popular belief, the Army of the Empire did not take part in the Thirty Years' War of 1618 to 1648.

[8] The figures for the contingents to be supplied by each Imperial Circle were little altered until the demise of the Empire.
