Manuel II of Portugal
Manuel died unexpectedly in his residence on 2 July 1932, via suffocation by an abnormal swelling in the vocal folds of his larynx, or tracheal oedema. The Portuguese government, at that time led by António Oliveira de Salazar, authorized his burial in Lisbon, after a state funeral. His body arrived in Lisbon on 2 August 1932, on board the British cruiser HMS "Concord" which had made the journey from the United Kingdom and sailed into the Tagus River to deliver the coffin of the former King. The body was received at Praça do Comércio, where a crowd of people had gathered to follow the coffin to São Vicente de Fora and the roads were inundated with people interested in seeing the funeral procession. His body was interred in the Royal Pantheon of the House of Braganza in the Monastery of São Vicente de Fora.
Clemente Domínguez y Gómez
In the 1990s, Gregory XVII was accused of sexual impropriety with several of his priests and nuns. In 1997 he admitted to it and begged forgiveness.
He died on 22 March 2005 in El Palmar de Troya, and was succeeded by Manuel Corral, who took the name Pope Peter II. Incidentally, the papacy of Gregory XVII closely overlapped that of Pope John Paul II. He died, aged only 58, a mere 11 days prior to the death of his "rival" as Pope. Ironically, John Paul II was 58 when he was elected by the College of Cardinals in October 1978.
