I don't have an embassy with the Celts. They declared war on me. I built an embassy with the Aztec. Aztecs and Celts are at war, according to the diplomacy screen. Question: Since I'm at war with a civ I have an embassy with, will I be notified if they make peace with the Celts? Will I be notified if they go to war with another AI? Or do you only receive embassy messages if you are at peace?
