How did Pentecostalism spread from the United States to Europe?

Pentecostalism spread from the United States to Europe through an immediate and rapid international missionary effort, driven by the belief that speaking in tongues facilitated the conversion of the world’s peoples before the Second Coming of Christ.1

Following the influential Azusa Street revival in Los Angeles, the movement was quickly transferred across the Atlantic. By the end of 1906, missionary work had already commenced in Norway. This expansion continued throughout 1907, reaching Scandinavia, Germany, Italy, and the Netherlands.1
