Constantine, in turn may have had to put aside Minervina in order to secure an alliance with the same man. Constantius did not dismiss Constantine as his son, and perhaps Constantine chose to follow his father's example. Whatever the reason, Constantine kept Crispus at his side.

Crispus was sentenced to death by Constantine's order in 326.
