World Government
The World Government consists of 170 countries from across the world. The Highest Authority and the leaders of the World Government are the Gorousei, who reside in the Holy Land of Maryjoa, which the World Government seems to be centered around. There still isn´t much known about the political ideals of the World Government nor about the complete political structure of the organization. So far it is only clear that there are people like the revolutionist Dragon, who don´t seem to share the same ideals.
While the structure of the World Government is as yet unknown, we do know that it relies on Three Powers to maintain control over the world. The Gorousei express their fear that the whole world might unravel at the seams if the balance of the Three Powers is disrupted. Any further specifics about the World Government are yet to be revealed.
WG Sections:
The Highest Authority of the World Government
Above all the politic leaders within the World Government, be it kings of countries or mayors of cities there´s the Gorousei, which translated means Five Elder Stars. As the name indicates, it is a group of five older man, that lead the large government. Not much is known about their politic ideals, except for two things.
The one thing is that Great Pirate Age is a huge thorn in their eyes. The Gorousei consider it such a big problem that they even consider obtaining Ancient Weapons in order to stop the Pirate Age. This attitude can be considered radical since the Gorousei themselves fears these weapons because of their destructive power.
The other thing we know is that they made a law that forbids anyone to research on info on the blank 100 years of the worlds history. The motives of this are unclear but what is clear is that anybody who breaks this law gets the death penalty.
Besides that, there hasn't been much revealed about the Gorousei so far.
During the series we have seen many actions of the World Government. They don't seem to care about how the world is going into since they have only been seen caring about themselves. They worry about losing power and would do anything to protect their jobs.
Let's look at the certain points of the story:
20 Years ago, they ordered the burning of the island of Ohara for researching history. Nico Robin was the sole survivor, and due to her escape, she was given a very high bounty because of her ability to read Poneglyphs. They blame her for the possibility of reviving the ancient weapons when truthfully, Robin never cared about them. It was thought that the ancient weapon was what the WG was afraid of, but in reality they were afraid of the ancient kingdom and its ideals. Robin was hated by the world due to the WG.
12 years ago, a man name Spandam came before the Gorosei and convinced them to change their mind in preventing the revival of the ancient weapeon. They easily fell for his deceptions by ordering him to seize the blueprints.
Marine Captain Morgan brutely ruled Shelltown, and the Gorosei did nothing about it.
- Orange Town was overridden by pirates, and the Gorosei did nothing about it.
Cocoyashi island was ruled by Arlong. He bribed a corrupted marine captain named Nezumi; the Gorosei did nothing about it.
- There was a Coup de Etete in Villa, and the Gorosei did not care about it.
- East Blue was mostly overrun by pirates, and the Gorosei did nothing about it. There weren't many marines patrolling the East Blue.
- Drum was suffering because of its selfish king, and the Gorosei did nothing about it.
- Arabasta was in war, and the Gorosei paid no attention to it until Smoker reported that Crocodile was behind it.
- Spandam, the CP9 chief was planning to overthrow the World Government, and the Gorosei was unaware of this.
The Three Great Powers
As of chapter 432, the long-standing question as to the identity of The Three Great Powers has been answered. The Powers are, as identified by a Vice Admiral, the Marine Headquarters, the Shichibukai, and the Yonko or Four Emperors, which is the third and last of the Powers to be named.
These three institutions exist in a delicate balance, not much is known about how this functions. It is however known that only the other two organizations are equivalent to the Yonko. Considering that these organizations are stated to be a balance and the fact that the loss of Crocodile threatened said balance, the most reasonable conclusion is that each organization is roughly equivalent in strength.
The Gorousei fear that if this balance gets disrupted, the world itself could collapse around them. It has not yet been fully explained so far as to why one of the Three Powers being weakened could pose such a dangerous threat. One possible reason is that this stems from the fact that only the Marines are fully under the control of the World Government. The Shichibukai appear to follow orders on a whim if at all and the Yonko are entirely outside of the World Government's control. A damage in the balance could swing the scales toward the Yonko and might lead to the Shichibukai reverting to their old ways in support.
The only other thing known about the Three Powers is that they are collectively the reason why the Grand Line is called the Pirates' Grave.
Security Forces
A large government wouldn´t function without some forces that establish law and order. The Security Forces consist of the following groups:
Member Governments
All over the world there´s over 170 countries that are all members of the World Government World Government. Within their own territory all these members have their own sovereign government that rules over it´s people. However in the large World Government itself those leaders are treated as equals and have a seat within it.
Among these member countries, not all are of the same kind. Some are really large countries with kings as their leaders others are simply big cities that are governed by mayors.
