"This great empire Charlemagne formed into a systematically organized State, and gave the Frank dominion settled institutions adapted to impart to it strength and consistency. This must however not be understood, as if he first introduced the Constitution of his empire in its whole extent, but as implying that institutions partly already in existence, were developed under his guidance, and attained a more decided and unobstructed efficiency. The King stood at the head of the officers of the empire, and the principle of hereditary monarchy was already recognized."
