The Anti-Messer Revolution was a complex series of events spanning decades that culminated in the end of the fascist Messer regime, the death of Linton Messer XI, and the disappearance of Fiona Messer in SEY 2792.

While no single incident can be credited with the downfall of the Messers, historians consider the murder of child laborer Anthony Tanaka at the hands of an Advocacy agent in SEY 2757 to be one of the key factors that led to a major rise in anti-Messer activism in the 28th century. The Akari-Kr.ē Treaty, which signaled the upcoming end of the Xi'an-Human Cold War, also played a significant role in sparking dissent against the Messer government. But it was the Massacre of Garron II, broadcast over spectrum by the activist group Tide, that fanned that dissent into a flame and kicked off open revolts against the Messers.

After twenty-two days of civil unrest, the Messers were removed from power, and Imperator Erin Toi took office.
