Verrat

The Verrat (ver-RAAT; Germ. "betrayal") is a powerful Wesen organization established in 1945 that serves the seven royal houses (the Seven Houses) whose goal is to maintain stability within the Wesen world. The Verrat depicted in the Grimm series is based on the conspiracy theories surrounding the German Revolution of 1918–1919, and it gets its name from Sebastian Haffner's series of books on the subject, known as Der Verrat.

Historical premise from real-world conspiracy theories
In November 1918, a group of German Empire rebels (the Verrat) formed the Weimar Republic and fueled a civil war within the empire. The Weimar Republic won the war, and in 1919, the government leaders signed the Treaty of Versailles, officially ending World War I and effectively marking a defeat for the German Empire.

Early Explanation
The Verrat, forming during World War II, has since infiltrated major political and law enforcement roles in every part of the world, and has been at the center of several struggles throughout history and throughout the world:


 * White Terror (1936 - 1963)
 * Multiple recent crises in Europe including the rise of Franco and Adolf Hitler
 * Recent turmoil in the Middle East
 * Arab Spring (2010 - present)

Renard's Explanation
The Verrat was created by the royal families in 1945 to defend them. It was originally composed of veterans of both sides in World War II. All were Wesen; most were Hundjägers.

Composition
There is little information on the Seven Houses that rule the Verrat. The organization's most common enforcers amongst the Wesen are Hundjäger, to the point that that species is synonymous with the Verrat. The Reapers are believed to be a (possibly semi-autonomous) branch of the Verrat dedicated to keeping the Grimms in line. Historically, the Grimms themselves have worked closely with the Verrat in a mercenary capacity, though to what extent this is true in the present day is unknown.
