Hogwarts Cultural Preservation Society

**The Hogwarts Cultural Preservation Society,** also known as **CPS**, is a student group at Hogwarts formed during the 1993-1994 school year in response to Theodore Nott being disinherited through the Ultimate Sanction.

## Goals

The CPS was intended to be a meeting place for Pureblood, Halfblood and Muggleborn wizards alike, where they could come together to teach eachother about the histories, customs and traditions of wizards and wizarding families.

Despite its original vision the CPS quickly became a breeding ground for blood purism, and the few Muggleborn members left quickly, most after attending a single meeting.

## History

### Origins

When the recently disinherited Theo No-Name arrived on Platform 9¾ a mob formed around him, which included Cassius Warrington, Pansy Parkinson, Victor Crabbe, Greg Goyle, Zacharias Smith, Hannah Abbot, Ernie Macmillan, Cedric Diggory, Cho Chang, Roger Davies, Marietta Edgecombe, Oliver Wood, Lavender Brown, Cormac McLaggen, a reluctant Justin Finch-Fletchley, and several other students Theo did not recognize. The group informed Theo he was not welcome at Hogwarts, leading to a great deal of confusion and outrage from those not affected by the Sanction, who quickly come to Theo's defense.

### Book 3 - The Death Eater Menace

The CPS was officially founded on 3 September 1993 when they held their first meeting. At the same time in another classroom a group of Pure-bloods, Muggle-borns, and Half-bloods founded the Society for the Prevention of Abusive Magic, or SPAM, which would soon become the CPS's chief rival. Cedric Diggory gives a speech where he explains that he is dismayed by the fact that some of his fellow students simply don't seem to understand the disdain they feel towards "the Outcast".

In February an article by Rita Skeeter implied that a Muggleborn conspiracy was behind the Azkaban Breakout, and after a speech by Daphne Greengrass on Alexander McAvity's more radical followers members of CPS began to deface SPAM posters in the hallways.

Eventually, in late March, the CPS tried to prank a SPAM meeting by putting a potion into a cake that would make them refer to each other by blood-based slurs, but Cedric Diggory and Cho Chang were caught at the scene by Head Boy Bobby Lattimer as they planted the cake.

In Harry's personal timeline SPAM received no prior warning about the prank and so Cedric and Cho weren't caught by Lattimer. After eating the cake several SPAM members, including Harry, became ill and had to spend the night in the infirmary. The prank also caused House Parkinson to lose 20,000 Galleons in under an hour due to Hermione's deal with Andrew Parkinson.

On April 30th 1994 the Wizengamot struck the Ultimate Sanction, which ended the artificial hatred and distrust many students felt towards Theo. Several CPS members, including Cedric Diggory and Cho Chang, apologised to Theo, but many abstained, and neither CPS nor SPAM was disbanded.

During the train ride home at the end of the school year Harry noticed that despite the absence of the Ultimate Sanction there was still visible division between the two groups.
