St. Nicholas, also called Nicholas of Bari or Nicholas of Myra, (flourished 4th century, Myra, Lycia, Asia Minor [near modern Demre, Turkey]; Western feast day December 6; Eastern feast day December 19), one of the most popular minor saints commemorated in the Eastern and Western churches and now traditionally associated with the festival of Christmas. In many countries children receive gifts on December 6, St. Nicholas Day. He is one of the patron saints of children and of sailors.
Nicholas’s existence is not attested by any historical document, so nothing certain is known of his life except that he was probably bishop of Myra in the 4th century. According to tradition, he was born in the ancient Lycian seaport city of Patara, and, when young, traveled to Palestine and Egypt. He became bishop of Myra soon after returning to Lycia. He was imprisoned and likely tortured during the persecution of Christians by the Roman emperor Diocletianbut was released under the rule of Constantine the Great. He may have attended the first Council of Nicaea (325), where he allegedly struck the heretic Arius in the face. He was buried in his church at Myra, and by the 6th century his shrine there had become well known. In 1087 Italian sailors or merchants stole his alleged remains from Myra and took them to Bari, Italy; this removal greatly increased the saint’s popularity in Europe, and Bari became one of the most crowded of all pilgrimage centres. Nicholas’s relics remain enshrined in the 11th-century basilica of San Nicola at Bari, though fragments have been acquired by churches around the world. In 2017 researchers dated one such relic fragment, a piece of hip bone, from a church in the United States and confirmed it to be from the 4th century.
