Eight-Nation Revolution

The Eight-Nation Revolution was a combination of worldwide rebellion efforts taking place in multiple countries as consequence of the Revolutionary Army's invasion of Mary Geoise during the Levely.

The Eight-Nation Revolution was first mentioned by Tensei, head of the Marines' Investigation Unit, sometime after the events of the Raid on Onigashima.

Background
While the reason for the revolution is not confirmed, in the Lulusia Kingdom it originated shortly before the Levely, as the royal family of King Seki and Princess Komane left along with the Royal Guards, leaving the country defenseless against Peachbeard, until the citizens were saved by four of the commanders of the Revolutionary Army, prompting the citizens to fight for themselves.

Overview
Following the invasion of Mary Geoise by the Revolutionaries and subsequent murder of Nefertari Cobra, with Sabo being labeled as the perpetrator, the populations of eight nations around the world decided to take upon arms and start a local revolutionary effort of their own to depose their monarchies, having been inspired by Sabo's actions in particular as they were reported in the news. As consequence of this, eight nations affiliated with the World Government ended up falling to rebel armies, who took advantage of the ongoing Levely at the time to establish new governments while their rulers were absent.

Among the countries that successfully deposed their monarchies was the Lulusia Kingdom. Its constituents imprisoned King Seki and his daughter Komane following their return from the Levely.

Aftermath
After Lulusia was liberated from its monarchy, Im and the Five Elders completely obliterated it from both the map and history, in an attempt to silence Sabo, who was hiding there after escaping Mary Geoise and witnessing Im's occupation in the Empty Throne, thus rendering the revolution of the country moot.
