Yes, Santa Claus is real. The real name of Santa Claus was Saint Nicholas, also known as Kris Kringle. The story dates back to the 3rd century. Saint Nicholas was born in 280 A.D. in Patara, near Myra in modern-day Turkey. The Saint donated all his inherited wealth and often travelled along the countryside, helping the poor and sick. One of the most famous stories about his pure heart is about the time when he saved three girls from being sold into prostitution by their own father, by providing the girls with a dowry so that they could get married. Over the years, Nicholas became popular for his deeds and came to be known as the protector of children. December 6 is commemorated as Saint Nicholas Day. His feast day was traditionally considered as a lucky day to make large purchases or for marriage purposes.
