Change in the Position of Caesar
So the second coalition was concluded in the summer of 694. Caesar was assured of the consulship for the following year and a governorship in due course; to Pompeius was promised the ratification of his arrangements made in the east, and an assignation of lands for the soldiers of the Asiatic army; to the equites Caesar likewise promised to procure for them by means of the burgesses what the senate had refused; Crassus in fine--the inevitable--was allowed at least to join the league, although without obtaining definite promises for an accession which he could not refuse.
It was exactly the same elements, and indeed the same persons, who concluded the league with one another in the autumn of 683 and in the summer of 694; but how entirely different was the position of the parties then and now! Then the democracy was nothing but a political party, while its allies were victorious generals at the head of their armies; now the leader of the democracy was himself an Imperator crowned with victory and full of magnificent military schemes, while his allies were retired generals without any army.
