A Little History: Halloween 2019 (also known as Allhalloween, All Hallows’ Eve, or All Saints’ Eve) occurs on the day before All Saints Day. It is a day that is dedicated to remembering the dead, including saints (hallows), martyrs, and all the faithful departed. Halloween is celebrated annually on October 31 in the United States and throughout the world. It is “widely believed” that Halloween originated from the ancient Celtic harvest festival, Samhain, and that this Gaelic observance was Christianized by the early Church. It is believed that the celebration of Halloween only made its way to the United States in the 19th Century by immigrants from Scotland and Ireland. The commercialization of Halloween (as we know it today) began in the 1900s, when postcards and die-cut paper decorations were produced. Halloween costumes started to appear in stores in the 1930s and the custom of ‘trick-or-treat’ appeared in the 1950s.
