It would be a mistake, however, to assume that these various states were under one form of government. There were almost as many forms of government as there were principalities; but they were all monarchical, and one sovereign happened to become the monarch of the whole. The house of Hapsburg, in which the imperial crown of Germany, the regal crowns of Hungary, Bohemia, and Lombardy, and the ducal crowns of Austria, Styria, the Tyrol, and nearly a dozen other principalities, became hereditary, acquired their possessions, not by conquest, but by election, succession, or other legitimate titles[30] recognised by the people. The descendants of Rodolph thus became the sovereigns of many separate states, each of which retained, as a matter of right, its own constitution. The sovereign, his chief advisers, and the principal officers of state at his court, were usually Germans by birth, or by education and predilection; but the constitution of each state--the internal administration, and those parts of the machinery of government with which the people came more immediately into contact--were their own. In some we find the monarchy elective, as in Hungary, Bohemia, and Styria; in all we find diets of representatives or delegates, chosen by certain classes of the people, without whose concurrence taxes could not be imposed, troops levied, or legislative measures enacted; and we find municipal institutions founded on a broad basis of representation. In none of them was the form of government originally despotic.
