You most likely will earn this trophy during your campaign, but if you didn't or you just want to get it out of he way quickly then start up a sandbox game with
unlimited money in the
modern era. Don't build anything, just place
one aircraft carrier with upgraded attacks. Now do things that make people unhappy, like demolishing their shacks and using the
"Martial Law" edict (found in the edicts menu by holding
and pressing
) and eventually rebels will attack your palace. The aircraft carrier should be sufficient to kill the rebels and the trophy will pop right away.
