Timeline Notes

The last time the Chudley Cannons Quidditch team won the League Cup was in 1892. In the 1990s the team were in the midst of a 100+ year losing streak (QA7).

Notes
As reported in the Daily Prophet, the Cannons managed to win a few games in the early 1990s - shocking their manager and fans. In spite of this they were probably still sitting at the bottom of the League Table that season (DP1, DP2, DP3, DP4).

Although the dates printed on the Daily Prophet Newsletters are:

DP1: 31 July 1998,
DP2: 8 February 1999,
DP3: 1 June 1999 and
DP4: 1 October 1999,
the timeframe for these events is 1992-1993.

Most students avoid him with the exception of Albus Dumbledore, who becomes one of his closest friends as a result (DH2)
