Louis I, Count of Nevers

Louis I of Nevers (1272–22 July 1322), son of Robert III of Flanders and Yolande of Burgundy, succeeded his mother as count of Nevers in 1280. In 1290 he married Joan, countess of Rethel, and ruled Rethel jure uxoris until his death.

Their children were Joan, later wife of John of Brittany, and Louis de Crécy, born in 1304, later count of Flanders, Nevers and Rethel. Louis died in Paris two months before his father, so he never ruled Flanders.
