The Branch Davidians (or the General Association of Branch Davidian Seventh-day Adventists) were an apocalyptic new religious movement founded in 1955 by Benjamin Roden. They regard themselves as a continuation of the General Association of Davidian Seventh-Day Adventists, established by Victor Houteff in 1935.

Houteff, a Bulgarian immigrant and a Seventh-day Adventist, wrote a series of tracts entitled the "Shepherd's Rod", which called for the reform of the Seventh-day Adventist Church. After his ideas were rejected by Adventist leaders, Houteff and his followers formed the group that later became known as "Davidians" and some of them moved onto a tract of land on the western outskirts of Waco, Texas, United States, where they built a community called the Mount Carmel Center, which served as the headquarters for the movement. After Houteff's death in 1955, his wife Florence took control of Davidian organization. That same year, Roden (a follower of Houteff), proclaimed what he believed to be a new message from God and wrote a series of letters presenting it to Davidians. He signed these letters "The Branch" believing that to be the new name Jesus had taken (according to biblical prophecies such as Revelation 3:12 and Zechariah 6:12-13) to reflect a new stage of his work in the heavenly sanctuary. Those who accepted Roden's teachings became known as Branch Davidians Seventh Day Adventists.

In 1957, Florence sold the original Mount Carmel Center and purchased 941 acres near Elk, Texas – thirteen miles northeast of Waco – naming the property New Mount Carmel Center. After the failure of Florence's prophecy of apocalyptic events on or near April 22, 1959, she dissolved the Davidian Association in 1962 and sold all but 77.86 acres of the New Mount Carmel property. Roden took possession of New Mount Carmel in 1962 and began his efforts to purchase the remaining 77.86 acres. On February 27, 1973, New Mount Carmel was sold to "Benjamin Roden, Lois Roden, and their son George Roden, Trustees for the General Association of Branch Davidian Seventh-day Adventists." From this point on, the property was simply known as Mount Carmel. Upon the death of Roden in 1978, his wife Lois became the next Davidian prophet at the compound.

In 1981, a young man named Vernon Howell, later known as David Koresh, came to New Mount Carmel and studied biblical prophecy under Lois Roden. By the end of 1983, Howell had gained a group of followers and they separated from the Lois's organization to form a new organization by the name "The Davidian Branch Davidian Seventh Day Adventist Association." Meanwhile, Lois continued to operate the Branch Davidian Seventh Day Adventist Association from Mt. Carmel Center near Waco. It is notable that Howell's group and the Branch Davidians (Lois's group) were two separate organizations with different leaders and different names operating from different locations from 1983 forward. It was not until 1987, after Lois had died, that Howell filed a document claiming to be the president of the Branch Davidian Seventh Day Adventist Association (even though he had been leading a competing group for several years). Also in 1987, Koresh and some of his followers went to Mt. Carmel center and engaged in a shootout with George Roden that eventually resulted in Koresh's group occupying the land. The actions of Koresh and his followers in 1987 (taking the name and property of the Branch Davidian SDA organization) are regarded by Branch Davidians who remained loyal to Lois Roden as an act of identity theft against them. Koresh's leadership of his group ended at the climax of the Waco siege of 1993, a 51-day standoff between members of the sect and federal agents, when New Mount Carmel was destroyed in a fire. Four agents of the U.S. Bureau of Alcohol, Tobacco, and Firearms (ATF) and two residents of Mt. Carmel were killed by members of the sect during the initial raid, while four sect members were killed by ATF agents on February 28, 1993. Seventy-six members of Koresh's group, many of them children, died in a fire that erupted during the siege on April 19, 1993.
