Francisco Pacheco was a Portuguese Jesuit missionary who lived from approximately 1568 to 1626. Born in Ponte de Lima, he decided to join the Society of Jesus at age twenty, motivated by the martyrdom of his uncle, Diogo de Mesquita. After traveling to the East and being ordained in Goa, he arrived in Japan in 1604. During periods of intense religious persecution, he was eventually captured in Nagasaki, where he was executed by being burned alive alongside several companions.
