Alphonse was the Count of Poitou from 1225 and Count of Toulouse from 1249. As count of Toulouse, he also governed the Marquisate of Provence.
Alphonse, as Count of Toulouse, recognised the autonomy of the commune of the town of Agen. In this illustration he takes an oath before the consuls with his right hand on the town ordinances, while sitting on a pedestal. The consul administering the oath is forced to go on his knees, symbolising Alphonse's lordship and the town's loyalty.
