Nearby, Maxentius also constructed the Circus of Maxentius. After the death of Maximian in 309 or 310, relations with Constantine rapidly deteriorated and Maxentius allied with Maximinus to counter an alliance between Constantine and Licinius. He allegedly tried to secure the province of Raetia north of the Alps, thereby dividing the realms of Constantine and Licinius (reported by Zosimus); the plan was not carried out, as Constantine acted first.
