The achievement of arms of Austria-Hungary was the country's symbol during its existence from the Austro-Hungarian Compromise of 1867 to its dissolution in 1918. The double-headed eagle of the ruling House of Habsburg-Lorraine was used by the common Imperial and Royal (k. u. k.) institutions of Austria-Hungary or the dual monarchy. Additionally, each of the two parts of the real union had its own coat of arms.
As the double-headed eagle was reminiscent of the insignia of the defunct Holy Roman Empire and also the symbol of the Cisleithanian ('Austrian') half of the real union, the Hungarian government urged for the introduction of a new common coat of arms, which took place in 1915, in the midst of World War I. The new insignia combined the coats of arms of the separate halves of the Dual Monarchy, linked by the armorials of the Habsburg-Lorraine dynasty and the motto indivisibiliter ac inseparabiliter ('indivisible and inseparable' ).
