[3] Constantine first rose to prominence in 913/4, when following the death of Emperor Alexander (r. 912–913), the Empress-regent Zoe Karbonopsina selected him and his brother as her personal councillors.
[2] Constantine Gongyles wielded great influence during the regency of Zoe (914–919), but he fell from power under Emperor Romanos I Lekapenos (r. 920–944).
The brothers were quick to change sides when Lekapenos gained the upper hand, but they are not mentioned in the sources during the latter's reign.
[4] Upon Lekapenos's deposition in December 944, however, Constantine Gongyles was appointed as the head of the Byzantine navy.
Basil the Younger (probably in the 960s), he and his brother lived in retirement and were spending their fortune on philanthropic and charitable causes.
