Baltasar Guedes de Sousa, born Baltasar Vaz Guedes, was the 7th Captain-major of Portuguese Ceylon. Guedes de Sousa was appointed in 1560 under Sebastian of Portugal, he was Captain-major until 1564. He was succeeded by Pedro de Ataíde Inferno.[1] [2]
He was the second-born son of Gonçalo Guedes by his wife Maria Rodrigues de Sousa, and paternal grandson of Gonçalo Vaz Guedes, 3rd Lord of Murça.[3]
He was thus a first cousin of another Gonçalo Vaz Guedes, father of the Portuguese humanist and rector of the University of Coimbra, Friar Diogo de Murça.[4]
He served in the military in Portuguese India and Ceylon together with his brother, Gonçalo Guedes.
During his tenure, he led several military operations in Colombo and in the Kingdom of Kotte, and was seriously wounded during these battles. It is therefore likely that he died around the year 1564.
