The Vermilionist Party, was a political party in Robloxia that existed from 1646 to the early 1700s. It was founded by Federalist politicians Eril Vandes and Levi Harmon in 1646 as an opposition to the Anti-Federalist government. The Vermilionist Party initially had an alliance with the Liberals, but as a result of Eril Cassel III's policy change, the Vermilionists moved away from the government. The views of the Vermilionists can be described as monarchist (allegedly) and progressive.
The party dissolved in 1722. The party had already been in crisis for a dozen or so years before its demise. In the early 1700s, Lawrence White left the Vermilionist Party to establish the Toupee Party.
