What it is
Cotton Mather was a leading intellectual figure in English-speaking colonial America during the late seventeenth and early eighteenth centuries. He served as a Congregationalist minister in Boston and wrote extensively on theology, morality, and natural history. Scholars often describe him as the first American Evangelical due to his prolific output and influence on religious thought. His work covered diverse subjects including demonology, astronomy, and medicine, reflecting the broad interests of the era's learned men.
Where it comes from
Born in Boston in 1663, Mather came from a distinguished family of Puritan ministers. His father, Increase Mather, and grandfathers were central figures in the establishment of the Massachusetts colony. Educated at Harvard College from a young age, he entered the clergy tradition established by his ancestors. His early life was shaped by the political tensions between the colony and the English Crown, which influenced his later public actions and writings.

Who does it
Mather was trained at Harvard College, where he studied Hebrew and the sciences. He joined his father as assistant pastor before becoming co-pastor of the Old North Meeting House in Boston. Unlike many contemporaries who focused solely on spiritual matters, Mather engaged with the scientific community, corresponding with European intellectuals and publishing reports to the Royal Society. His status as a minister gave him authority, but his involvement in politics and science set him apart as a unique figure in colonial society.
Peoples and places
Mather is primarily associated with the Puritan communities of New England, particularly in Boston and Salem. His influence extended through his writings and correspondence across the Atlantic.

At a glance: who, where and when




What people believe
As a Puritan theologian, Mather operated within a worldview that acknowledged the reality of the invisible world, including demons and spirits. This belief system underpinned his defense of the Salem witch trials, where he argued for the legitimacy of spectral evidence. His theological framework integrated faith with the emerging experimental science of his time, seeing no contradiction between studying nature and believing in divine intervention.
How scholars and sceptics see it
Historians have long debated Mather's legacy. In the nineteenth century, writers like Nathaniel Hawthorne criticized him as a chief agent of mischief during the witch trials. Modern scholars tend to downplay his direct role in the legal proceedings, noting that he never called for an end to the trials but also did not hold official judicial power. His reputation has been further complicated by his advocacy for smallpox inoculation, which faced violent opposition from some citizens despite saving lives.
Cautions and what is closed
Mather's life illustrates the dangers of mixing religious authority with political and medical controversy. His defense of the witch trials damaged his standing among many colonists and later generations. His promotion of inoculation led to public unrest, with opponents viewing it as a violation of traditional beliefs or divine will. These controversies highlight the risks faced by innovators in rigid social structures.
Compare and confuse
Mather is often compared to his father, Increase Mather, though he produced more written works. He is distinct from other Puritan leaders by his active engagement with secular science and international correspondence. His role in the witch trials sets him apart from ministers who opposed the hysteria, marking him as a polarizing figure in American religious history.
