Following the Bourbon Restoration she was renamed Duc d'Angoulême, after Louis Antoine, son of the future King Charles X, and launched on 30 August 1814, entering service on 26 November.

The next year, during the Hundred Days, she briefly took back the name of Iéna between March and July.

[1] Iéna was struck on 31 December 1864, and served as the central hulk for the Toulon reserve fleet until 1915.
