The letter in full: "Carissimo in Christo fili salutem et Apostolicum benedictionem.

Just a few weeks before the audience of the ambassador with the Pope, Charles's Catholic army, supported by troops from Spain and the Papal State, were defeated in the Battle of La Roche-l'Abeille on 25 June 1569. On 3 October 1569, the Catholic forces won the Battle of Montcour but Charles, on the verge of bankruptcy, would still be forced to sign the Peace of Saint-Germain-en-Laye on 8 August 1570 that guaranteed specific rights and responsibilities to the French Huguenots. Two years later, Charles gained lasting notoriety for his ambiguous role in the St Bartholomew's Day massacre against the Huguenots that violently ended the fragile religious peace. - Traces of folds and seal. With added date "2 aoust 1569" in French to the address (twice). Some browning and minor stains. Several tears to the paper border..
