In which year was the Assemblies of God founded?

The Assemblies of God was founded in 1914, making that the correct answer. This year marked the formal establishment of the denomination during a significant gathering of Pentecostal leaders in Hot Springs, Arkansas. The founding represented a pivotal moment in the history of the Pentecostal movement, as it sought to unify various groups and establish common beliefs and practices.

The year 1900 is often associated with the beginning of the modern Pentecostal movement due to the events surrounding the Azusa Street Revival, but it does not reflect the official founding of the Assemblies of God. The years 1950 and 1980 are too late to pertain to the establishment of the denomination; while there were developments and expansions during those decades, the foundational event occurred in 1914. This context highlights the importance of the year in which the Assemblies of God was officially organized and recognized as a distinct denomination within the broader Pentecostal movement.
