Allegiance is the fourth full-length studio album by Firewind, first released on 10 July 2006. Vocalist Chitral Somapala was replaced by Apollo Papathanasio and Stian L. Kristoffersen made way for Mark Cross on drums, ending the previous tradition of changing line-up between albums. It was recorded at JM Studio, Mölnlycke, Sweden, in February 2006, mixed by Fredrik Nordström with Patrik J. Sten in Studio Fredman, Göteborg, Sweden, in March 2006, then mastered by Peter In de Betou at Tailor Maid productions in Stockholm.
