The Imperial-Royal Landwehr (German: Kaiserlich-Königliche Landwehr) is the land component of the Armed Forces of Austria, serving the emperor of the Holy Roman Empire and the archduke of Austria for the protection of Germany and Imperial lands. The largest branch of the Austrian Armed Forces, the Landwehr is responsible for retaining order in Habsburg lands. The land forces primarily consist of militia and conscripted lower class citizens, as well as royal units trained for border protection and in wartime.
