None of the purported witches or sorcerers executed in the 1692 Salem Witch Trials were burned at the stake; 19 were hanged and one crushed. However, in Europe it was standard to burn folks convicted of witchcraft, often while still alive. During the era of witch hysteria some 50,000 folks were executed.
