Christian revivalism is increased spiritual interest or renewal in the life of a church congregation or society, with a local, national or global effect. This should be distinguished from the use of the term "revival" to refer to an evangelistic meeting or series of meetings (see revival meeting). Proponents view revivals as the restoration of the church itself to a vital and fervent relationship with God after a period of moral decline.
Within Christian studies the concept of revival is derived from biblical narratives of national decline and restoration during the history of the Israelites. In particular, narrative accounts of the Kingdoms of Israel and Judah emphasise periods of national decline and revival associated with the rule of various wicked or righteous kings, respectively. Josiah is notable within this biblical narrative as a figure who reinstituted temple worship of Yahweh while destroying pagan worship. Within modern church history, church historians have identified and debated the effects of various national revivals within the history of the US and other countries. During the 18th and 19th centuries, American society experienced a number of "Awakenings" around the years 1727, 1792, 1830, 1857 and 1882. More recent revivals in the 20th century include those of the 1904–1905 Welsh Revival, 1906 (Azusa Street Revival), 1930s (Balokole), 1970s (Jesus people), 1971 Bario Revival and 1909 Chile Revival which spread in the Americas, Africa, and Asia among Protestants and Catholics.
Many Christian revivals drew inspiration from the missionary work of early monks, from the 16th-century Protestant Reformation (and Catholic Counter-Reformation) and from the uncompromising stance of the Covenanters in 17th-century Scotland and Ulster, that came to Virginia and Pennsylvania with Presbyterians and other non-conformists. Its character formed part of the mental framework that led to the American War of Independence and the Civil War.
