Christophorus I (23 February 879-12 August 942) was the Emperor of the Byzantine and Frankish Empire from 27 October 879 until the dissolution of the position in 893 with the Magnam Europae charter. Crowned on his eleventh birthday, he became the Holy Roman Emperor in 890. Despite a brief revocation of the title from the Pope, which led to the Italian Wars, Christophorus held power in Europe until his death in 942.
