If the ability to effectively influence a message is a sign of power, then Muhammad or Jesus could be considered the most powerful people of all time. They were both capable of spreading religious texts all across the world. These religious texts are still devoutly followed by people today. Their abilities to spread their messages through the Quran and Bible created lasting religious followings that influenced generation after generation. Therefore, the ability to influence people by spreading a message does not necessarily make a leader the most powerful person of all time.
