Charlemagne, or Charles the Great, was the King of the Franks, King of the Lombards, and Emperor of the Holy Romans who ruled between 768 and 814 AD.

Missi or Missi Dominici is the Latino term for "envoys of the Lord". They are officials appointed by and on behalf of Charlemagne to supervise the administration, order and justice.

Charlemagne selected Christian archbishops and bishops and abbots, and sent them throughout his kingdom, so that they might execute justice, to ensure respect for the king, to control the government of the military dukes and administrative counts, to receive their oath of allegiance, to let the king's will be known, at times by distributing basic laws around the empire, and to supervise the clergy of their assigned region.

Charlemagne's notion of fidelity was to ensure order: people keep abiding laws and that the emperor's vision and decisions can be effective all over his kingdom. They were crucial to the success of his government because without order, Charlemagne couldn't rule over a very large empire which comprises the current Western and Central Europe.

Charlemagne believed that all freemen should swear an oath of fidelity to him as emperor so that he knew that his followers were loyal and that he  felt safe around his people.
