The Unofficial World Club Championship History
Thanks to the lovely people at the RSSSF, I was able to trace this championship from the 2000 FIFA World Club Championship. This date was chosen because it was the first tournament in which a club from every confederation was represented. Now there is probably someone working on a similar history going back to the first FA Cup final, or Preston North End winning the inaugural Football League title, but this will suffice for now.
