Cornelia li Britannia is the second princess of the Holy Britannian Empire,
Commander-in-Chief of the Imperial Army, and the second Viceroy of Area 11 in the series.
She is extremely skilled in a Knightmare Frame combat, as is proven by her conquest
of the Middle East, making it Area 18. Her personal knight is Gibert Guilford, who is
known as the Spearhead of the Empire and her general is Darlton.

other terrorist groups she destroys most of the groups, except for the Black Knights. When

Cornelia doesn't like the idea. She also did not like the idea of Euphie picking and Honorary
Britannian as her personal Knight. When Euphie is Killed Cornelia takes it very hard.
In the aftermath of the Rebellion, Cornelia is labeled MIA, because she goes underground
to clear Euphie's name. She also learns that Zero is Lelouch, learning about geass in the
process. While underground she learns about her father has ties to geass, and tries to bring
Geass to the surface, but she is captured by V.V. and later on Lelouch. She helps Lelouch
take down V.V. Siegfried using a damaged Akatsuki.
