Robert I, Count of Artois

Robert I of Artois (25 September 1216 – 8 February 1250) was the first Count of Artois, a younger son of Louis VIII of France. He received Artois as his appanage in 1237 and married Matilda of Brabant.

In 1240 Pope Gregory IX offered him the imperial crown against Frederick II, but he refused. On the Seventh Crusade with his brother Louis IX, he charged into Mansourah with Templars and English troops without the king's knowledge; on 8 February 1250 he was trapped in the narrow streets and killed. His posthumous son Robert II succeeded.
