Pentecostalism began in North America and spread across the globe. It grew out of the ferment of American religious life and manifested elements of Wesleyan Methodism and Holiness theology.

After the 1960s the charismatic movement or "second wave" provided further momentum to the movement, and this was supplemented by indigenous Pentecostalism in the developing world. (Contains 7 notes.)
