Founded in London by a Methodist street preacher named William Booth in 1865.
Booth was dissatisfied with what he felt was an all too traditional approach to evangelism and he set out to form a group of evangelical street preachers with a focus to bring the poor, thieves, prostitutes, gamblers, and drunkards to a saving knowledge of Jesus Christ. He preached hope and salvation with an intent to connect them with a church where they could be discipled. A printer called his growing group a “volunteer army”. When Booth saw this in print, he crossed out “volunteer” and replaced it with “salvation”. This group is theologically akin to the Arminianist Methodist movement of the day. It has grown to a worldwide membership and has become most well known for charitable work
