Rosicrucianism is a spiritual and cultural movement that arose in early modern Europe in the early 17th century after the publication of several texts announcing to the world a new esoteric order. Rosicrucianism is symbolized by the Rosy Cross or Rose Cross. There have been several Rosicrucian organizations since the initial movement was founded, including the Order of the Golden and Rosy Cross (1750s–1790s), the Societas Rosicruciana in Anglia (1865–present), and the Hermetic Order of the Golden Dawn (1887–1903).
