Alexander Henderson was a Scottish theologian, and an important ecclesiastical statesman of his period. He is considered the second founder of the Reformed Church in Scotland. He was one of the most eminent ministers of the Church of Scotland in the most important period of her history, namely, previous to the middle of the seventeenth century.

Covenanters were members of a 17th-century Scottish religious and political movement, who supported a Presbyterian Church of Scotland and the primacy of its leaders in religious affairs. The name is derived from covenant, a biblical term for a bond or agreement with God.
