The Restoration Movement is a Christian movement that began on the United States frontier during the Second Great Awakening (1790–1840) of the early 19th century. The pioneers of this movement were seeking to reform the church from within and sought "the unification of all Christians in a single body patterned after the church of the New Testament."

Christianity is an Abrahamic monotheistic religion based on the life and teachings of Jesus Christ. It is the world's largest and most widespread religion with roughly 2.4 billion followers, comprising around 31.2% of the world population. Its adherents, known as Christians, are estimated to make up a majority of the population in 157 countries and territories. Christians believe that Jesus Christ is the Son of God, whose coming as the Messiah was prophesied in the Hebrew Bible and chronicled in the New Testament.
