Spiritualists are individuals who believe in the ability to communicate with spirits of the deceased. They often practice mediumship, where a medium acts as a conduit between the living and the spirit world. This belief system emerged in the 19th century, particularly in the United States, and is associated with movements like the Fox Sisters who claimed to communicate with spirits through knocking sounds. Spiritualism emphasizes personal experience and the idea that spirits can provide guidance and insight. Many Spiritualists hold gatherings or séances to connect with spirits, seeking messages that can offer comfort or advice. The movement has influenced various aspects of New Age beliefs and practices.
