The military forces of the Order of Saint George of Carinthia started as an ally of the Holy Roman Empire but remained neutral.

The Siege of Wiener Neustadt was a siege that lasted 18 months. It was part of the Austro–Hungarian War between Frederick III, Holy Roman Emperor and Matthias Corvinus, King of Hungary. It marked the end of a series of sieges, whereas Hungary then controlled Styria and the Lower Austria.

The city was alerted many times during the Austro-Hungarian War. First in 1477 Grand master Johann Siebenhirter of the newly founded (1469) Order of Saint George of Carinthia "defenders of environment" occupied the city in order to defend the city. They were order dedicated to defend the borders of Austrian lands from the Eastern menaces. Originally set against the Ottomans the order found itself in between Matthias of Hungary and the Holy Roman Emperor Frederick the latter who imposed as the founder knight of the order. Siebenhirter placed the headquarters of the Order from Millstatt to Wiener Neustadt. In May 1478 he commanded the cottars of the mortgaged Hungarian villages Kismarton and Fraknó – of which he was the captain of, and in which he had spawned the Ordership – to drudge-work in the fortification labour of the city. After the siege of Vienna he visited Matthias to compromise the status of Neustadt. As a result, they concluded a truce regarding the territories owned by the Order and exchanged their prisoners of war. The treaty meant the immunization of the Order off the Austro-Hungarian war. This was a contradicting situation as Siebenhirter kept his captain office of Neustadt in the mean time. Siebenhirter also committed himself that his knights at Wartenstein would refuse any support request from the Emperor. Also he could continue to run the Order in the lands under Matthias' authority.
