No, the Salem witch trials were not in Oregon. They took place in Salem, Massachusetts, in the late 17th century, specifically from 1692 to 1693. The trials were a series of hearings and prosecutions of people accused of witchcraft in colonial Massachusetts. The hysteria surrounding witchcraft during this period led to the execution of 20 individuals, mostly women, and the imprisonment of many others.
Oregon, on the other hand, became a U.S. state in 1859, long after the Salem witch trials ended. While witch hunts and similar accusations have occurred in various places throughout history, the specific events referred to as the Salem witch trials are uniquely tied to Salem, Massachusetts.
