I've been doing a bit of research and it seems that Pentecostalism seems to have certain ties to evangelicalism in general.
Why exactly does it just appear in 1901 without any branch from another denomination?
From what I can remember, Pentecostalism isn't tied to any other denomination. It began as it's own movement--some would say a movement of the Holy Spirit--and even today many consider it to be a movement rather than a denomination because it is found in a variety of denominations, including Catholicism.
