The organization "Assemblies of God" was born in the wake of the revivals that took place in the early twentieth century. Those who took part in this resurrection were filled with the Holy Spirit, just as He was poured out on Jesus' disciples and followers at the feast of Pentecost. Those who participated in this revival were called Pentecostals. They experienced speaking in tongues as a sign of receiving the Holy Spirit Baptism, just as it did on the day of Pentecost. There were other supernatural manifestations, such as prophecy, interpretation of tongues, spiritual conversions, healings (Acts 2).

With the exception of worldwide statistics on the outpouring of the Holy Spirit over the centuries, the movement appeared in Topeka, Kansas, USA, in January 1901, when the Holy Spirit carried on its wings the awakening in various parts of the earth. Participants in this movement who were baptized with the Holy Spirit were not well received by the churches to which they belonged. In response, many broke off relations with the denominations they belonged to and formed various organizations. Limited distance and communication contributed to the rapid isolation of Pentecostal churches from each other.
