Question: Walter Scott & Alexander Campbell helped to stabilize the Campbell movement which lead to establishing The Mahoning Baptist Association in what year?
Context: The Mahoning Baptist Association was an association of Baptist churches that was established in 1820 in Ohio's Mahoning Valley.  Two prominent early Restoration Movement leaders, Alexander Campbell and Walter Scott, were closely affiliated with the Mahoning Association.  The Association was dissolved in 1830. Walter Scott (1796 – April 23, 1861) was one of the four key early leaders in the Restoration Movement, along with Barton W. Stone, Thomas Campbell and Thomas' son Alexander Campbell.  He was a successful evangelist and helped to stabilize the Campbell movement as it was separating from the Baptists. After leaving the American Baptist Association over church representation matters, the association was formed at Little Rock, Arkansas in 1950 as the North American Baptist Association, the Baptist Missionary Association of America adopted its current name in 1969.  Its concentration is in the Southern United States, but as a result of its mission work, the association has churches across the United States and throughout the world.  According to the BMAA Missions Department, "the sun never sets on BMA Missions."  The BMAA currently supports the most missionaries around the world than ever before in the association's history. The Bapticostal movement is a movement in some Baptist churches towards adopting certain elements of the charismatic movement.  The word Bapticostal is a combination of "Baptist" and "Pentecostal".  The term has been used in a limited manner to describe a worship style of high-tempo Contemporary Christian music accompanied with spontaneous shouts, clapping and hand raising.  But it also describes those churches where members profess to have and exhibit the charismatic gifts that are practiced in Pentecostalism such as speaking in tongues, being slain in the Spirit, or being granted a word of knowledge.  The prevalence of such beliefs within Baptist churches worldwide is unknown.  In some unions or conventions it hardly exists (e.g. Eastern Europe) but in others (Australia, New Zealand) it is common.  In the United States, it has been estimated that among Southern Baptist churches, 5% of the churches could be classified as Bapticostal, and the numbers are growing.  According to a study in 1989, 69% of Baptist churches belonging to the Baptist Union of New Zealand, the main Baptist association in New Zealand, identified positively with the charismatic movement. Originally known as the Vandalia Baptist Association (1840–1880), this association was named the Centalia Baptist Association when churches from Centralia, Mt. Vernon and other churches south of Centralia, Illinois joined the Association to become the Centralia Baptist Association in 1881.  It eventually became renamed as the Kaskaskia Baptist Association (Southern Baptist) in 1912. The Vandalia Baptist Association, a precursor to the Centralia Baptist Association and Kaskaskia Baptist Association, was organized in 1840 and centered in the Vandalia, Illinois, area.  It originated from the Saline Fraternity, which was organized in 1834, which in turn was an offspring of the Old South District of the Friends of Humanity. Alexander Campbell Mansion, also known as Campbell Mansion or Alexander Campbell House was the home of minister Alexander Campbell and his family in West Virginia.  His wife Margaret's father John Brown had owned a large amount of property in Bethany, including this; the house dates to 1793. The Redstone Baptist Association was an association of Baptist churches in Western Pennsylvania.  The early Restoration Movement leader Alexander Campbell and the congregation he led, the Brush Run Church, were members of the Association for several years during the early 19th century. The Convención Nacional Bautista de México (National Baptist Convention of Mexico) is the oldest and largest Baptist group in Mexico.  The first evangelical church in Mexico was a Baptist church organized on January 30, 1864 in Monterrey, Nuevo León.  James Hickey, a Baptist and a member of the American Bible Society, constituted this church with himself and four other members - Thomas Westrup, José Maria Uranga, Arcadio Uranga, and Mrs. Hickey.  By 1869, Westrup and the Uranga brothers had organized six more churches.  The American Baptist Home Mission Society and the Southern Baptist Convention sent about fifty missionaries to Mexico before the beginning of the 20th century.  In 1884, the Coahuila Baptist Association was organized in Saltillo, and in 1885 the Nuevo León Baptist Association was organized in Monterrey.  After the turn of the century, Alejandro Treviño, John Cheavens and James Chastain proposed the idea of organizing a national convention.  Forty-three church messengers met at the Primera Iglesia Bautista (First Baptist Church) in Mexico City in September 1903.  From this gathering came a provisional constitution for the National Convention, and the groundwork for missionary, theological and publications ministries.  This began a transition of the work from leadership by foreign missionaries to leadership by national pastors.  In 1904, the National Convention selected Alejandro Treviño to represent them at the first Baptist World Congress, from which was formed the Baptist World Alliance. The Disciples of Christ (Campbell Movement) were a group arising during the Second Great Awakening of the early 19th century.  The most prominent leaders were Thomas and Alexander Campbell.  The group was committed to restoring primitive Christianity.  It merged with the Christians (Stone Movement) in 1832 to form what is now described as the American Restoration Movement (also known as the Stone-Campbell Restoration Movement).
