What if...
Ancient kingdom was ruled by ancestor of BB. Will explain why BB is marked by IMU
Joyboy was like oden. Wanted freedom sailed to the sea like luffy. Thus, the first pirate.
Other Nations envied the ancient kingdom tech and were frustrated by their rule so wanted the power themselves.
It was the struggle of power between the two - AK and WG with joyboy wanted feedom for everyone
