Governmental Structure
Three distinct elements ruled Austria-Hungary, including: the Hungarian government, the “Austrian” or Cisleithanian government, and a unified administration under the monarch. Hungary and Austria maintained separate parliaments, each with its own prime minister. Those two were linked by a government under a monarch wielding, in theory, absolute power, although in practice the power of the monarch was limited. The monarch’s common government was responsible for the army, navy, foreign policy, and the customs union.
Within Cisleithania and Hungary certain regions, such as Galicia and Croatia enjoyed special status with their own unique governmental structures.
A Common Ministerial Council, composed of three ministers for the joint responsibilities (joint finance, military, and foreign policy), the two prime ministers, some Archdukes and the monarch, ruled the common government. Two delegations of representatives, one each from Austria and Hungary, met separately and voted on the expenditures of the Common Ministerial Council, giving the two governments influence in the common administration. However, the ministers were ultimately responsible only to the monarch, and he had the final decision on matters of foreign and military policy.
Overlapping responsibilities between the joint ministries and the ministries of the two halves caused friction and inefficiencies. The armed forces suffered particularly from overlap. Although military direction was determined by the unified government, the Austrian and Hungarian governments each remained in charge of “the quota of recruits, legislation concerning compulsory military service, transfer and provision of the armed forces, and regulation of the civic, non-military affairs of members of the armed forces.” Needless to say, each government could have a strong influence over common governmental responsibilities. Each half was quite prepared to disrupt common operations to advance its own interests.
Relations over the half-century after 1867 between the two halves of the Empire (in fact the Cisleithan part contained about 57% of the combined realm's population and a rather larger share of its economic resources) were punctuated by repeated disputes over shared external tariff arrangements and the financial contribution of each government to the common treasury. Under the terms of the Ausgleich, these matters were determined by an agreement which was to be renegotiated every ten years, which created political turmoil each time the agreement was up for renewal. The disputes between the halves of the empire culminated in the mid-1900s in a prolonged constitutional crisis triggered by disagreement over the language of command in Hungarian army units, and deepened by the advent to power in Budapest (April 1906) of a Hungarian nationalist coalition. The common arrangements were renewed provisionally (October 1907, November 1917) on an "as is" basis.
Ethnic relations
The dominant ethnic group in each half of the Empire constituted a minority in the area which it controlled: Germans numbered only some 36% of Cisleithania's population, and Magyars slightly under a half of Hungary's.
Czechs (the majority in the Czech lands, i.e.Bohemia, Moravia and Austrian Silesia), Poles and Ukrainians (in Galicia), Slovenes (in Carniola, Carinthia and southern Styria, mostly today's Slovenia) and Croats, Italians and Slovenes in Istria each sought a greater say in Cisleithan affairs.
