John Davion was the heir to Richard Davion, the First Prince who had come to power after the death of Joseph Davion at the hands of the Draconis Combine Mustered Soldiery during the War of Davion Succession. The slow response of the Star League and the Star League Defense Force to the War of Davion Succession and the invasion of the Federated Suns drove a wedge between the First Lord and Richard Davion and led to a reduction in trade between the Federated Suns and the Terran Hegemony, as well as the enactment of the Preparedness Act of 2735, which was a vehicle for Richard Davion to begin an increase in the size of the Armed Forces of the Federated Suns without technically breaching the letter of the Council Edict of 2650.
This cooling of relations between the Camerons and the Federated Suns continued during John's reign as he focussed on directing the industrial and technical strength of the Federated Suns into expanding the AFFS and ensuring that it became the most technologically advanced military after the Royal Divisions of the SLDF. The AFFS grew dramatically during John's reign, almost doubling in size between the passing of the Preparedness Act and 2765, but relations between John and the Star League were not antagonistic. While John was dedicated to the Federated Suns and his first priority would always be the safety of his realm, he continued to view the Star League as the vehicle which could bring that safety and prosperity to the Federated Suns. General Aleksandr Kerensky of the SLDF regarded John as a man of strong character and will, whilst First Lord Richard Cameron II was favourably inclined towards John amongst the various rulers of the Great Houses.
