William Booth founded the Salvation Army in 1865 as a Christian organization to help the needy in England. He was inspired to help the poor after becoming unemployed himself for a period of time. The Salvation Army was established with a military structure and uniforms to emphasize discipline and organization in carrying out its mission. It has since expanded worldwide to provide social services to communities. Key beliefs include abolishing poverty by establishing social programs like homes and training centers for those in need.
