Old Norse religion, also known as Norse paganism, also called the most common name for a branch of Germanic religion which developed during the Proto-Norse period, when the North Germanic peoples separated into a distinct branch of the Germanic peoples. It was replaced by Christianity during the Christianization of Scandinavia. Scholars reconstruct aspects of North Germanic religion by historical linguistics, archaeology, toponymy, and records left by North Germanic peoples, such as runic inscriptions in the Younger Futhark, a distinctly North Germanic extension of the runic alphabet. Numerous Old Norse works dated to the 13th century record Norse mythology, a component of North Germanic religion.
