Let me summarise a game so far for you: playing Morocco King Continent
It was very peaceful continent on my side. Everyone shook hands and there were no wars, a lot of research agreement and stuff. Venice is mostly friendly with me. We made a lot of Declaration of Friendships from time to time. The only red incident was when my spy was caught once, from this point onwards I didn't spy on him again.
It was very peaceful continent on my side. There were no wars, until I create one, No maybe two.
Somehow in Modern era everyone in my continent tried to convince me to join a war against Venice. I declined them all but was interested in funding a proxy war. I bribed Korea and Austria, Venice's border to declare war against it and pretend to be innocent. (rather cheap)
Several turns later, Venice who use to have Declaration of Friendship with me seemed to find out and suddenly denounced me.
He was right to do so but I wonder how he found out about my scheming?
