The Senate's power was gradually reduced over the course of history, although it still existed into the 13th century. From the seventh century on, it could be said that it was less of an institution than a class of dignitaries,[3] as many of its remaining powers as a body were removed under legal reforms by the emperors Basil I and Leo VI. The Senate itself retained considerable prestige, especially in the 11th century when the "court party" came to power following the death of Basil II.
