Austro-Italian ironclad arms race
Austria's defeat in the Seven Weeks War forced Austria to determine a new set of foreign and domestic policies for the future, as Austria's interests since the days of the Holy Roman Empire had primarily been found in Italy and Germany. The Empire thus reformed itself into the Austria-Hungarian Empire following the adoption of the Austro-Hungarian Compromise of 1867 (German: "Ausgleich"), which re-established the sovereignty of the Kingdom of Hungary and placed Hungarians within the Empire on an equal footing with Austrians. Under the "Ausgleich", Emperor Franz Joseph I would be crowned as King of Hungary, while a separate parliament at Pest with powers to enact laws for the lands of the Holy Crown of Hungary would be established.
Imperial Army (Holy Roman Empire)
During the imperial interregnum of 1740-1742, Habsburg troops no longer formed the army for the Emperor, but that of the Queen of Hungary. During the Austrian War of Succession, Queen Maria Theresa and the Austrian House of Habsburg, fought for their survival within the European system of power. She initially lost her battle for the imperial crown for her husband, Francis Stephen of Lorraine. With the acquisition of the crown by Charles VII of the Bavarian House of Wittelsbach, units from the Electorate of Bavaria formed the Imperial Army for a short time, from 1742 to 1745. A year after the loss of the imperial crown, the Archduchess of Austria and Queen of Hungary directed her troops to wear green instead of gold for officers' sashes and for the regimental flags. Gold has always been considered an imperial attribute.
After the imperial election of Maria Theresa's husband, Francis I, the Habsburg troops were given back their imperial status. Although Maria Theresa took the title of empress, she put no value on her coronation as empress. This was reflected in the title of her army, which was now called "Roman Imperial-Royal" ("römisch kaiserlich-königlich"). The colloquial, shorter term, "Austrian", established itself during the Seven Years' War (1756-1763) and subsequent conflicts in the War of Bavarian Succession (1778/1779), the Russo-Austrian war against the Turks (1787-1792) and the Napoleonic Wars.
