How did Dom Manuel II die?
Manuel II of Portugal
via suffocation
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.[16] 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.
