Theoderic V was King of Spain from 788 to 803, and nominal Western Roman Emperor until 800. The son and successor of Theoderic IV, he came to power during a period of civil strife when the power of Spain was at its lowest for over a hundred years. By 795 he had managed to establish his rule over the whole kingdom, but his armies were left weakened and unable to withstand the emerging empire of Charlemagne. Theoderic V died in 803. He was succeeded as King by his brother, Witiges.
