The Feast Day of Ignatius of Loyola is observed worldwide on July 31. This day commemorates Ignatius of Loyola, the founder of the Society of Jesus, who was born in Spain in 1491. Initially uninterested in religion, he underwent a significant transformation after suffering severe injuries from a cannonball at the age of 30, which led him to seek solace in religious texts during his recovery. In 1541, he established the Society of Jesus, which received papal approval. Ignatius administered the society until his death on July 31, 1556. He was beatified in 1906 and canonized in 1622. The feast day celebrates his contributions to the Catholic Church, and he is recognized as a patron saint of various cities in Spain, including San Sebastián and Bilbao, as well as of soldiers and educators.
