The scary, uncontrollable spirits, ghosts and witches that terrified mankind over millennia had lost their grip by the middle of the 20th century. Yet Halloween just wasn’t complete without things to scare us – and the entertainment industry was ready to fill that need with haunted house theme parks, terrifying movies and unforgettable horror stories in books, magazines and TV serial shows. This final installment of the Halloween story will look at why and under which circumstances we enjoy being scared – and what story elements scare us.

Much of the evolution of Halloween celebrations after the Second World War took place in America since most of Europe was focused for many years on economic recovery from near total destruction. Halloween costumes of every imaginable sort could be purchased and parties with amazing baked treats became commonplace. Scary Halloween movies were widely enjoyed and major theme parks created popular spooky haunts to terrify adults and children alike.

By the early years of the 19th century, much of the religious fervour around Halloween caused by the Reformation had been replaced by games and parties throughout the British Isles to celebrate the end of the harvest and beginning of Winter. The suffering and starvation of millions of people caused by the Great Irish Potato Famine created a flood of immigrants to the United States – immigrants who brought their Halloween celebration customs with them and made them part of the American culture.

The story of Halloween took a darker turn in the Middle Ages with the splintering of the Catholic Church and the start of the Reformation. Luther’s refusal to recant his Ninety-Five Theses at the Diet of Worms resulted in his excommunication and the creation of the Protestant Church. Many of the elements of Halloween celebrations we enjoy today began as horrible tortures of women wrongly accused of practicing witchcraft.

The Western Roman Empire was a hostile environment for the early Christian Church until the conversion of Constantine and the Edict of Milan. With that guarantee of religious tolerance, however, the Church expanded rapidly throughout Europe and into what is now the UK and Ireland and encountered once more the Celtic celebrations of the dead. The way in which the Church adapted their customs and festivals to Christian celebrations makes up the next fascinating chapter in the story of Halloween.

The end of summer, the harvest, and the beginning of the long, dark, cold days of winter were terrifying times for ancient people. The ghosts of ancestors could return to the land of the living and no one could be sure of surviving until warmth and the sun returned again the following Spring. For people completely dependent on the whims of an unpredictable, natural world, they sought comfort in ceremonies and festivals. This is a bit of their story.

It’s almost time for Halloween again. Where did the idea come from and why do we celebrate it on 31 October. It’s a fascinating story and we will tell you all about it over the next three weeks. Check back here on Sundays and Wednesdays to read the next installment.
