Icelandic Zuism, a movement inspired by ancient Sumerian religion,

 gained traction around 2015–2016 primarily as a form of protest against Iceland's parish tax system, where registrants could redirect funds away from established churches. It was officially recognized as a religion in Iceland from 2013 until 2025, but its popularity has since declined, with membership dropping significantly after the initial surge. There's no evidence of active, dedicated online discussion boards or forums specifically for Icelandic Zuists today. The movement had a now-defunct official website (zuistar.is), and while there is a Facebook page for Zuism with a few hundred likes, it appears largely inactive and lacks community features like group discussions. Scattered mentions appear in broader online spaces like Reddit threads or general pagan/neopagan forums, but nothing organized or Zuism-specific. Zuism draws from Sumerian mythology, where the Anunnaki are a collective group of deities (literally "offspring of heaven and earth") who decree fates and maintain cosmic order. Icelandic Zuism isn't deeply doctrinal—it's more political than spiritual in practice—but it references the Sumerian pantheon. Among Anunnaki figures, Enlil (god of wind, storm, and authority) and Enki (god of water, wisdom, and creation) are the most prominently mentioned as key deities, often alongside An (god of heaven) as part of a supreme trinity. Enlil is frequently depicted as a leading authority figure in Sumerian texts, making him arguably the most central or "popular" in the context of Zuism's inspirations. Other notable Anunnaki include Ninhursag (goddess of fertility) and Inanna (goddess of love and war), but they receive less emphasis in Zuist descriptions.
