Hello, I have been a long time Lurker, and
Things We know.
One Piece exists, it is a physical thing that isn’t some metaphor like Gol D. Roger’s hat or Friendship or something along those lines, and what is there is something that would throw the world into chaos, and whatever is there is connected to “The Men with D in their names.” (Chapter 576, Pages 10-11)
We also know that The world government was deathly afraid of Gol D. Rodger after he made it to Laugh Tale, Renamed him to Gold Rodger, and attempted to scour his bloodline from existence. (Chapter 576, Page 10. Chapter 551 Page 6.)
We know that there was an Ancient Kingdom that predates the World Government, one that at some point had become powerful enough to Dominate the Planet, and eventually that The Group that would be known as the current World Government under the control of the Celestial Dragons/Imu.
! The Ancient Kingdom ruled the world, and much like the World Government they ruled from the Red Line, which was artificially created by “Continent Pullers” such as Oars. The rulers of this Kingdom were the clans who had D. in their name.
! Each generation each clan of D would send their strongest member to the end of the Grand Line to be judged, the most worthy of them claiming the crown of“King of the World” for that generation. This meant that even if the person in charge wasn’t fully good they were strong and bold enough to find the 4 Road Poneglyphs and make it to the True Final Island.
! This created a mostly stable system until the centuries before the Void Century,Where I think that we had two brothers from the same clan, one of which truly desired to be King of the World, the other who didn’t have a particular desire for power and fame, but wanted to see the world. We will use the name Pepsi and Coke for these two respectively. Pepsi for the one who wanted to rule, and Coke for the one who wanted to explore.
! Much like Teach,Pepsi wanted power, but when pushed into a corner he would scream in pain and cowardice. This made him “Not a True D.” as Whitebeard Called Teach.(Chapter 576, Page 11). He and Coke set out to make Pepsi the King of The World in his generation, with Coke effectively carrying him the entire way as his second in command.
! When the Brothers reached what would become known as Laugh Tale, Pepsi thought that he would be crowned King, however the being in charge of Laugh tale at the time chose Coke who was “A real D.” This enraged Pepsi.
! Now there are two possible paths that this could take, One Possibility is that Im is Pepsi and that he formed the World Government as a power grab to put himself on The Throne, but that leaves the question as to why hide that Im is in charge, why do the whole Empty Throne thing?
! I believe that when Pepsi tried to take the mantle of King of the World, it caused a full on Civil War in the Ancient Kingdom, and Im or Im’s ancestor used this Civil War to gather 20 Nations together and overthrow the entire Ancient Kingdom, putting his family “on the empty throne” while setting up the conspiracy to hide that someone was ruling the world.
! Why would Im or Im’s family do this? Well it is easier to keep countries in line if they don’t know they are being ruled by a dictator, completely erasing the history of the D. Clans and the contest for The Last Island. The only remnant of what once was is what would be known as Laugh Tale, but I also think that there is something to do with the Straw Hat under Mary Geoise, something that only those who carry the will of D. and have gone to Laugh Tale can trigger.
! Centuries later Gol. D Rodger finds out he is sick and decides “I want to go to the end of the Grand Line.” gets to the end and finds out that there is something hidden in the world, then goes to Laugh Tale and finds out the story of the Ancient War, and decides that the World Government should fall, but he can’t because he is ill, so he entrusts it to others, calling out from his execution platform that “Everything I have I left at the end of the Grand Line.”
! That was Rodger’s plan, a plan to bring another D, one who isn’t dying to Laugh Tale and overthrow the World Government. That is why he turned himself in,because he knew the Government would make a big show of killing him..so he used that against The World Government to bring another member of the D. Clans to Laugh Tale, someone young and powerful enough to fight against the World Government.
! Also..there is probably a crap ton of Gold and Jewels there..because Luffy and crew deserve some bling because we all know Luffy doesn’t care much about Politics. He is gonna punch Blackbeard and Im in the face anyways because they are gonna deserve it by the end..but Luffy still deserves a giant pile of Gold, and likely what is going to happen if Luffy ends up as King of the World..is that he dumps it on Vivi saying something along the lines of "I don't wanna be king cause that doesn't sound like fun, Vivi is a princess she can do it kay BYE!"
Other people who I think are in on the in on the secret.
! Garp – I think Gol D. told him like he told Whitebeard. Gol D. trusted Garp as much as he trusted anyone in his crew, and knowing what is at the end of the Grand Line would give him a reason to want Ace and Luffy to be “goods strong marines.” We know he dislikes the Celestial dragons, he wished to either have Ace and Luffy to rise to the station of Admirals and use the power of the marines to overthrow the Celestial Dragons.
! Sengoku – This one I am less sure on, but he and Garp were close friends so Garp may have let him in on the plan to use Ace or Luffy to bring down the World Government and establish a more fair form of justice.
! Doflammingo – He knows a secret that the Five Elders are so afraid of being revealed that they are willing to bend over to his will despite being a Pirate in League with Kaido, and in my opinion a Hat isn’t really enough to justify The Celestial Dragons getting blackmailed,
! Marco – We know that Whitebeard knew what was at Laugh Tale, and Whitebeard was going into an all out war when the crew went to Marineford and there was no promise that he would get out alive. Given that Laugh Tale and the Will of D are connected Whitebeard would have been a complete fool to not tell somebody the secret because they needed Ace to get to LaughTale.
! Xebec – Probably had some idea as to what was there, implied to Gol D. that there was something at the end of the Grand Line and started the entire story.
! The Person who reaches Laugh Tale gets to be King of the World, Im is a usurper who is trying to prevent someone from getting the crown so he can Rule “The Empty Throne.”
! Also there is gold there, because Luffy doesn’t want to be King of the World.
Okay Arlong Park go rip it all to shreds, sorry if the formatting is goofy I wrote it up in Libra Office.
The only problem with these kind of theorys is…. Why would the "simple" information about the past and the fact everything is ruled by 1 supreme king shake the world and bring chaos? These things dont sound bad enough to remove the world goverment . Maybe the current World governemtn was bad in the past but these were not the same people who are ruling now (also nobody seems to give a fuck about the Celestian dragons which are as evil as possible).
Also Rayhleigh told luffy to get the information and create his own opinion on it meaning it cant just be black and white
