On 30 November 147, Faustina gave birth to a girl, named Domitia Faustina. It was the first of at least fourteen children (including two sets of twins) she would bear over the next twenty-three years. The next day, 1 December, Pius gave Marcus the tribunician power and the imperium—authority over the armies and provinces of the emperor. As tribune, Marcus had the right to bring one measure before the senate after the four Pius could introduce. His tribunican powers would be renewed, with Pius', on 10 December 147.[118]
