JEAN DE ARC, I played as the julii and smashed the Gauls and I was the only 1 to take all of there provinces. But that only unlocked the gauls.

JOCK STRAP if you particpated in Carthages demise, the game makes them unlocked. Do'nt know how it figures it in wether all you had to do was win a sea battle and win or if you have to take over at least 50 percent of there land, as for me I took over 3 of carthages 6 territories. Even though I was'nt the one to deliver the crushing blow it unlocked that faction for me
