287 on insists on a singular and indivisible Rome, a patrimonium indivisum. As the panegyrist of 289 declares to Maximian: "So it is that this great empire is a communal possession for both of you, without any discord, nor would we endure there to be any dispute between you, but plainly you hold the state in equal measure as once those two Heracleidae, the Spartan Kings, had done." Legal rulings were given and imperial celebrations took place in both emperors' names, and the same coins were issued in both parts of the empire. Diocletian sometimes issued commands to Maximian's province of Africa; Maximian could presumably have done the same for Diocletian's territory. Campaigns against Rhenish tribes Campaigns in 286 and 287 Maximian realized that he could not immediately suppress Carausius and campaigned instead against Rhenish tribes. These tribes were probably greater threats to Gallic peace anyway and included many supporters of Carausius. Although Maximian had many enemies along the river, they were more often in dispute with each other than in combat with the Empire. Few clear dates survive for Maximian's campaigns on the Rhine beyond a general range of 285 to 288. While receiving the consular fasces on 1 January 287, Maximian was interrupted by news of a barbarian raid. Doffing his toga and donning his armor, he marched against the barbarians and, although they were not entirely dispersed, he celebrated a victory in Gaul later that year. Maximian believed the Burgundian and Alemanni tribes of the Moselle-Vosges region to be the greatest threat, so he targeted them first. He campaigned using scorched earth tactics, laying waste to their land and reducing their numbers through famine and disease. After the Burgundians and Alemanni, Maximian moved against the weaker Heruli and Chaibones. He cornered and defeated them in a single battle. He fought in person, riding along the battle line until the Germanic forces broke. Roman forces pursued the fleeing tribal armies and routed them. With his enemies weakened from starvation, Maximian launched a great invasion across the Rhine. He moved deep into Germanic territory, bringing destruction to his enemies' homelands and demonstrating the superiority of Roman arms. By the end of 287, he had the advantage and the Rhenish lands were free of Germanic tribesmen. Maximian's panegyrist declared: "All that I see beyond the Rhine is Roman."
