Saint Pierre Chanel Day is observed in Wallis and Futuna, a French territorial collectivity in the South Pacific, every April 28. This public holiday honors Saint Peter Chanel, the patron saint of Futuna, who was a Catholic priest and missionary. Chanel joined the Society of Mary in 1831 and arrived on Futuna in 1837, where he initially gained the favor of the local king, Niuliki. However, as Chanel began to preach Christianity, the king grew fearful of losing his authority, leading to Chanel's martyrdom on April 28, 1841. He was later beatified in 1889 and canonized in 1954 by Pope Pius XII. The day is marked by religious observances and celebrations in recognition of Chanel's contributions to Christianity in the region.
