Grand Duke - Byzantine Grand Dukes

Byzantine Grand Dukes

For more details on this topic, see Megas doux.

The Latin title dux (the etymological root of duke), which was phonetically rendered δουξ in Greek, was a common title for imperial generals in the Late Roman Empires (west and east), but note it was lower in rank than Comes (the etymological root of Count). In the Eastern Empire, a dux ranked just below a strategos.

Under the latter, exclusively Byzantine theme system, the commander of a theme was often styled a dux. The title of "Grand Duke" (megas doux) was created by Alexios I Komnenos and was conferred upon the commanding admiral of the Byzantine navy. The title remained in use until the Empire's end, by which time the office had become a virtual chief minister, heading both civil and military administration.

Famous quotes containing the word grand:

    Philosophy is written in this grand book—I mean the universe—
    which stands continually open to our gaze, but it cannot be understood unless one first learns to comprehend the language and interpret the characters in which it is written. It is written in the language of mathematics, and its characters are triangles, circles, and other geometrical figures, without which it is humanly impossible to understand a single word of it.
    Galileo Galilei (1564–1642)
