The opera Agnes of Hohenstaufen by the Italian composer Gaspare Spontini had its premiere on 12 June 1829 at the Royal Opera in Berlin.
Agnes of Hohenstaufen, the emperor's cousin, is engaged to be married to the son of Henry the Lion, Henry "Palatinus", but the war brings this alliance into doubt.
He grew up in England and became count palatine of the Rhine through his 1193 marriage to Agnes, heir to the Count of Staufen.
