Amanieu d'Albret (1478 – 1520) was a French Roman Catholic cardinal.
Amanieu d'Albret was born in the Kingdom of France ca. 1478, the son of Alain I of Albret, and Frances, Countess of Périgord.[1] His older brother Jean married Catherine of Navarre.[1] His uncle Louis d'Albret was also a cardinal. He had three illegitimate children, one son and two daughters.[1]
Early in his career, he became a protonotary apostolic.[1] He was also Archimandrite of San Rufo.[1]
On 19 July 1499 he became apostolic administrator of the see of Comminges but on 1 January 1502 the cathedral chapter of Saint-Bertrand-de-Comminges Cathedral chose another candidate as bishop.[1]
Pope Alexander VI made him a cardinal deacon in the consistory of 20 March 1500.[1] The pope sent him the red hat on 2 October 1500 and he received the deaconry of San Nicola in Carcere on 5 October 1500.[1]
From 4 May to 10 October 1500 he was administrator of the see of Oloron.[1] He was administrator of the see of Pamiers from 14 March 1502 until 1506.[1]
After Cardinal Giuliano della Rovere sought refuge in Savona, Cardinal d'Albret was secretly despatched on 21 June 1502 to bring him back, but failed in this mission.[1]
He participated in both the papal conclave of September 1503 that elected Pope Pius III. and the papal conclave of October 1503 that elected Pope Julius II.[1] After this second conclave he had to leave Rome.[1]
He was administrator of the see of Vannes from 8 January to 14 October 1504; of the see of Bazas from 4 December 1504 until his death; of the see of Lescar from 6 October 1507 until 20 June 1515; and of the see of Pamplona from 13 May 1510 until 1512, and again from 1517 until his death.[1]
He participated in the plot of cardinals against Pope Julius II.[1] In 1511, he attended the schismatic Council of Pisa even after the pope threatened him with excommunication.[1] There, he was a strong supporter of the French party.[1]
After the death of Julius II, he participated in the papal conclave of 1513 that elected Pope Leo X.[1] The new pope absolved Cardinal d'Albret (along with Cardinals Guillaume Briçonnet and René de Prie) and confirmed him in his offices.[1] He also served as administrator of the see of Pamiers from 1514 until his death.[1] He became the cardinal protodeacon on 3 September 1520.[1]
He died in Casteljaloux on 20 December 1520.[1] He is buried in Casteljaloux.[1]
