I have never heard of Mageia
I'll bet you had (before today):
https://wiki.trinitydesktop.org/MageiaInstall and its addition to https://wiki.trinitydesktop.org/Category:Documentationdate back more than 3 years.
1998 - Mandrake forked off RedHat 5.1, featuring KDE instead of Gnome: https://web.archive.org/web/20040404122826/http://www.distrowatch.com:80/table.php?distribution=mandrake
(2004 - first Ubuntu release)
2005 - Conectiva Linux was merged into Mandrake and the name was changed to Mandriva. The Mandrake line makes up most of Mandriva's Distrowatch history, going all the way back to 1998: https://web.archive.org/web/20130925163717/http://distrowatch.com/table.php?distribution=mandriva
2010 - Mageia forked from Mandriva: http://distrowatch.com/table.php?distribution=mageia
