The coronation was the main symbolic act of accession to the throne of a Byzantine emperor, co-emperor, or empress. Founded on Roman traditions of election by the Senate or acclamation by the army, the ceremony evolved over time from a relatively simple, ad hoc affair to a complex ritual.
Anachronistic depiction of a coronation by being raised on a shield, from the Madrid Skylitzes. The crowned figure is meant to be Michael I Rhangabe, although there is some debate concerning the identity of the two figures, as the scene appears to be drawn from a lost original source. It has been proposed that the image depicts the coronation of a co-emperor (left) by a senior emperor (right).

Constans II, nicknamed "the Bearded", was the Byzantine emperor from 641 to 668. Constans was the last attested emperor to serve as consul, in 642, although the office continued to exist until the reign of Leo VI the Wise. His religious policy saw him steering a middle line in disputes between the Orthodoxy and Monothelitism by refusing to persecute either and prohibited discussion of the natures of Jesus Christ under the Type of Constans in 648. His reign coincided with Muslim invasions under, Umar, Uthman, and Mu'awiya I in the late 640s to 660s. Constans was the first emperor to visit Rome since the fall of the Western Roman Empire in 476, and the last one to visit Rome while it was still held by the Empire.
