Maximian and Constantine may have met at Augusta Treverorum (Trier, Germany) in 307, possibly in late summer. Maximian made Constantine "augustus". Constantine married Maximian's daughter Fausta. (This could have been in late summer, September, or as late as 25 December. Historians are not in agreement about the date.) At the start of his reign, only the lands that Constantine controlled accepted Constantine as "augustus". Then, the lands that Maximian's son Maxentius controlled also accepted that Constantine was an "augustus".
