Allegiance is the debut studio album by American deathcore band As Blood Runs Black.

[6] As Blood Runs Black was formed in 2003 in Los Angeles by vocalists Louie Ruvalcaba and Enrique "Ricky" Martin, guitarists Bijon Roybal and Kyle Hasenstab, bassist Richard Reyes, and drummer Brian "Animal" Matute.

Matute would depart the band shortly after its formation and was replaced by Hector "Lech" De Santiago.

De Santiago recruited vocalist Chris Blair, guitarist Ernie Flores, and bassist Nick Stewart to resume work on the band's debut.

Allegiance was recorded in early 2006 and was self-produced by the band, with Baron Bodnar serving as executive producer.
