Odo was the elected King of West Francia from 888 to 898. He was the first king from the Robertian dynasty, the parent house of the House of Capet. Before assuming the kingship, Odo was the count of Paris. His reign marked the definitive separation of West Francia from the Carolingian Empire, which would never be reunited.

In medieval historiography, West Francia or the Kingdom of the West Franks constitutes the initial stage of the Kingdom of France and extends from the year 843, from the Treaty of Verdun, to 987, the beginning of the Capetian dynasty. It was created from the division of the Carolingian Empire following the death of Louis the Pious, with its neighbor East Francia eventually evolving into the Kingdom of Germany.
