Kingship was hereditary. Though
succession to the throne was generally decided
by law of primogeniture, that is, the eldest son
succeeding his father there were many
exceptions to this rule. Sometimes kings were
even elected by nobles and councilors As head
of the government, the King was overseer of all
administrative activities of his realm. He was the
supreme judge, and he usually led his army to
the battlefields.
