Has any else ever had to "Declare War on the Barbarians"? I am playing on a medium size (50X80) map. I am playing a OCC (raging hordes). The year is 1764AD. I am playing Carthage when I noticed that a Barbarian Leader was just outside a Mongol city (I am at peace with the Mongols). So I sent a Crusader by boat and landed next to the leader. When I went to attack, I was asked if I wanted to "Declare War on the Barbarians". I clicked "YES" and was over-ruled by the Senate. On the next turn, a Mongol catapult killed the leader.
