Romulus slew Remus with a shovel over a dispute about which one of the two brothers had the support of the local deities to rule the new city and give it his name.

Supposedly, Romulus had stood on one hill and Remus another, and a circle of birds flew over Romulus, signifying that he should be king.

After founding Rome, Romulus not only created the Roman Legions and the Roman Senate, but also added citizens to his new city by abducting the women of the neighboring Sabine tribes, which resulted in the mixture of the Sabines and Romans into one people.

In 305, Diocletian and Maximian resigned, and the former caesares Constantius and Galerius became Augusti. Although with Constantine and Maxentius two sons of emperors were available, they were left out from the new tetrarchy, and Severus and Maximinus Daia were appointed Caesars. Some sources (Lactantius, Epitome) state that Galerius hated Maxentius and used his influence on Diocletian that Maxentius be ignored in the succession; maybe Diocletianus also thought that he was not qualified for the military duties of the imperial office. Maxentius retired to an estate some miles from Rome.
