The Company for Propagation of the Gospel in New England and the parts adjacent in America was a missionary society active in America from 1649 until 1786. It was first called the "New England Company" in 1770. Most secondary literature uses that name for convenience and to distinguish it from other missionary societies. The company was first chartered in 1649 as the "President and Society for the Propagation of the Gospel in New England," largely in response to John Eliot's missionary efforts. After the Restoration (1660), it was rechartered as the "Company for Propagation of the Gospel in New England and the parts adjacent in America." The New England Company was very powerful and influential, in large part because it was a coalition between Anglicans and Dissenters. It supported a range of missionaries from the Mayhews to the Sergeants to Moor's alumnus Samuel Kirkland. After the Revolution, the New England Company refocused its attentions on New Brunswick and Canadian Indians. Wheelock had a very rocky relationship with the New England Company. Initially, it supported Wheelock's efforts. The Company funded Occom's education at Moor's and paid him a small salary during his time among the Montauketts. However, from 1765 onwards, its relationship with Wheelock rapidly deteriorated. The Company opposed the fundraising tour of Great Britain and went so far as to interfere with it by sending a widely circulated letter to England questioning Occom's background. The New England Company also interferred with Titus Smith's mission to Onaquaga by sending a rival missionary, Mr. Moseley, and stealing Titus' interpreter, Elisha Gunn. In 1767 it formally withdrew its financial support from Wheelock on the grounds that the fundraising tour had raised sufficient money. It is unclear what led the New England Company to suddenly change its stance towards Wheelock. Perhaps it wanted exclusive power over missionary distribution in New England, or perhaps it was thought that focusing on education over numbers in the field was counterproductive. Most secondary sources have conflated the New England Company's Boston Board and the Society in Scotland for Promoting Christian Knowledge's Boston Board, an easy mistake to make since both are sometimes referred to as the Boston Board and both vigorously opposed Wheelock. Any secondary source's statement about either should be carefully researched.

The Connecticut Board of Correspondents of the SSPCK was founded in 1764 at Wheelock's request. He wanted a public board's support so that his school would seem more credible since it was a private organization with no charter. The Boston Board of the SSPCK would not do since they generally opposed Wheelock, so his solution was to petition the SSPCK for his own board. The SSPCK acquiesed, and the board met for the first time on July 4, 1764. While the board was nominally separate from Wheelock's school, in practice, he exercised considerable control over it. The members of the board were Wheelock's handpicked friends and supporters: Jonathan Huntington, Elisha Sheldon, Samuel Huntington, Solomon Williams, Joseph Fish, William Gaylord, Samuel Moseley, Benjamin Pomeroy, Richard Salter, Nathaniel Whitaker, David Jewett, and Wheelock himself. Wheelock used this board to send Occom and Whitaker to England, hold exams for Moor's Indian Charity School, and generally support his designs. When Wheelock moved to New Hampshire, he tried to establish a New Hampshire Board as well, but by that point the SSPCK was much more cautious when it came to Wheelock's plans and refused. The Connecticut Board dissolved in 1771 as Wheelock was its raison d'etre.

The Society in Scotland for Propagating Christian Knowledge (SSPCK) is a Presbyterian missionary society formed in 1709 and still active today. The SSPCK was founded to anglicize the Scottish Highlands, which at the time were predominantly Gaelic and had little in common with lowland Scotland. British Protestants identified many of the same “problems” in Gaelic and Native American society, and in 1730, the SSPCK expanded into the colonies via a board of correspondents in Boston. Although most of Wheelock’s contact with the SSPCK took place through its Boston, New Jersey/New York, and Connecticut boards, he did work directly with the SSPCK parent organization during Occom’s fundraising tour of Great Britain (1765-1768). Since Occom was technically sent to England by the Connecticut Board of the SSPCK, it was only natural that his tour include a visit to the parent organization in Edinburgh. The SSPCK, headed by the Marquis of Lothian, issued a bulletin to its member churches which allowed Whitaker and Occom to collect a substantial sum of money with little time or travel. While most of the money that Occom raised went into a trust under the Earl of Dartmouth (the English Trust), the money he raised in Scotland (approximately £2,500) went into an SSPCK-controlled fund that ultimately proved difficult to access. While the English Trust essentially gave Wheelock a blank check for the money it controlled (much of which went toward clearing land and erecting buildings for Dartmouth College), the SSPCK was much more stringent about requiring that the money Occom had raised be applied only to Native American education. As was often the case in the 18th-century British-Atlantic world, religious politics were a powerful motivator. Wheelock and the SSPCK both practiced Reformed Protestant Christianity, but New Hampshire was an Episcopalian colony. To make Wheelock’s Reformed Protestantism more palatable to Episcopalian New Hampshire, the New Hampshire governor attempted to make the Anglican Bishop of London a member of the English Trust and possibly the Dartmouth Trustees (the Bishop of London seems to have never replied to the invitation). Dartmouth’s geographic association with the Episcopalian Church, in addition to concerns about the use of the fund, gave the SSPCK an incentive to withhold money from Wheelock. It only issued Wheelock £190 throughout his life, although it did provide financial support to Samuel Kirkland out of the fund. It is worth noting that Wheelock seems to have been well aware that he would have trouble getting money from the SSPCK: he went through the entirety of the English Trust’s fund before soliciting the SSPCK. Subsequent Dartmouth presidents struggled to access the money, with limited success, until 1893. In 1922, the SSPCK concluded that since Moor’s Indian Charity School had become defunct, it was within its rights to devote the remainder of the fund—then valued at £10,000—to other missionary operations.

Connecticut is a state in southern New England that borders Massachusetts to the north and the Long Island Sound to the south. Its name is derived from the Algonquian "Quonehtacut," meaning "long river," referring to the Connecticut, which runs from the border with Canada into the Long Island Sound. The area was originally inhabited by Algonquian-speaking Pequots, Mohegans, and Quinnipiacs. European settlers took advantage of tribal divisions to establish dominance in the region. Dutch explorer Adrian Block sailed up the Connecticut River in 1614, establishing an active Dutch trading post at what is now Hartford. English claims to Connecticut began in 1630, but settlement truly began when Thomas Hooker, a Congregationalist minister now known as "The Father of Connecticut," left Boston to found Hartford in 1636. Hartford became the center of the Colony of Connecticut, which did not receive its charter until 1662 when Governor John Winthrop, Jr. secured it from Charles II. In 1665, the Colony of New Haven, established in 1638 by the Puritan minister John Davenport, joined the Colony of Connecticut under this charter. Early settler relations with local Indians were tense, and encouraged the New England colonies of Massachusetts Bay, Plymouth, Connecticut, and New Haven to unify as the "United Colonies" or "New England Confederation" and fight together, with Indian allies, in the Pequot War and again in King Philip's (Metacom's) War. These wars helped establish a specifically Connecticut and specifically American identity; the latter drove the colony to join the rebellion against Britain in 1776. Occom, born into a Mohegan household in Connecticut, was closely associated with the Colony and retained strong ties to the region throughout his life. He converted to Christianity in 1743 when the Great Awakening spread through Connecticut, and inspired Wheelock's Indian Charity School, which was founded in Lebanon, CT in 1754. He also became involved in the Mason Land Case, a long-standing dispute over the ownership of reserve Mohegan lands in Connecticut. Wheelock also had strong ties to Connecticut, moving his Indian Charity School only when the colony would not grant it a charter.

Mohegan is a village in southeastern Connecticut at the site of the present-day town of Montville, and is the location of the Mohegan Indian Reservation. The village gets its name from the Mohegan Tribe, or wolf people, who split from the Pequots in the early 17th century under the leadership of the sachem Uncas. In the 1720s, the Mohegans requested the colony of Connecticut provide them with an English educator. An English minister and schoolteacher named John Mason (no relation to Captain John Mason) moved to Mohegan in order to provide English-styled education to the Mohegans, convinced his sponsors, the New England Company, to build a schoolhouse at Mohegan, which eventually served as a boarding school for other Native American children from the surrounding area. During the 17th century, the Mohegan Tribe became embroiled in a complicated controversy over control of Mohegan land — known as the Mason Land Case or, more specifically, Mohegan Indians v. Connecticut — that included the village of Mohegan. The Tribe claimed that it never authorized a transfer of their lands, held in trust by the Mason family, to the colonial government. In 1662, the colony of Connecticut was incorporated by a royal charter, which included the disputed tribal land. The land controversy was revived in 1704 when descendants of John Mason, the original trustee, petitioned the Crown on behalf of the Mohegans, but the suit was finally decided against the Tribe in 1773. Born in Mohegan, Occom became involved in the Mason Land Case and vehemently argued for the rights of the Mohegan Indians to maintain their land, opposing Eleazar Wheelock and other ministers in the area. Although Occom left Mohegan for a 12-year mission with the Montauk Indians of Long Island, he returned at the end of 1763 with his large family to build a house in Mohegan, establishing it as his base of operations. Even after the creation of the Brothertown settlement in Oneida country, for which he served as minister, Occom continued to commute back and forth from Mohegan; he didn't sell his house in Mohegan and move his family to Brothertown until 1789. Many members of his family remained in Mohegan, including his sister Lucy Tantaquidgeon, who lived there until her death at 99 in 1830.

Niantic is a village located in East Lyme, a seaside town in southeast Connecticut on the Long Island Sound. The land was occupied by the Niantic tribe when the Europeans arrived. The Dutch claimed the area in the 17th century, but when the British claimed this same land as part of their colonies, the Dutch forfeited it to the British in a 1627 trade agreement. The village housed both preachers and a schoolhouse, and missionaries came to the village for the purpose of converting and assimilating the tribe. This effort intensified in the 1740s with the influence of the First Great Awakening. Increasingly dispersed and dispossessed of land, many Niantic Indians followed Occom and Joseph Johnson to upstate New York in the 1770's where they settled Brothertown.

The first English immigrant to settle on a peninsula in a harbor on the northeastern coast of North America the local Algonquin Indians called "Shawmet" was William Blackstone in 1629. A year later, John Winthrop arrived with a group of English Puritans and other settlers and named the area Boston after his hometown in Lincolnshire, England. The colony quickly developed representative political institutions that would help shape a democratic nation. Over the next few centuries, Boston emerged as an intellectual and educational center, and, because of its excellent harbor, became a leading commercial hub and a primary port for North America. It is the capital and largest city of the Commonwealth of Massachusetts, and the largest city in New England. Boston was the home for the Boards of Commissioners of several overseas religious societies who sent missionaries throughout the colonies in the 18th century, and was the site of many important events of the American Revolution.

Eleazar Wheelock was a New Light Congregationalist minister who founded Dartmouth College. He was born into a very typical Congregationalist family, and began studying at Yale in 1729, where he fell in with the emerging New Light clique. The evangelical network that he built in college propelled him to fame as an itinerant minister during the First Great Awakening and gave him many of the contacts that he later drew on to support his charity school for Native Americans. Wheelock’s time as an itinerant minister indirectly brought about his charity school. When the Colony of Connecticut retroactively punished itinerant preaching in 1743, Wheelock was among those who lost his salary. Thus, in 1743, he began operating a grammar school to support himself. He was joined that December by Samson Occom, a Mohegan Indian, who sought out an education in hopes of becoming a teacher among his people. Occom’s academic success inspired Wheelock to train Native Americans as missionaries. To that end, he opened Moor’s Indian Charity School in 1754 (where he continued to train Anglo-American students who paid their own way as well as students who functionally indentured themselves to Wheelock as missionaries in exchange for an education). Between 1754 and 1769, when he relocated to New Hampshire, Wheelock trained approximately 60 male and female Native American students from nearby Algonquian tribes and from the Haudenosaunee (Iroquois) of central New York. At the same time, he navigated the complicated politics of missionary societies by setting up his own board of the Society in Scotland for Propagating Christian Knowledge, although he continued to feud with the Boston Board of the SSPCK and the London Commissioners in Boston (more colloquially called the New England Company). By the late 1760s, Wheelock had become disillusioned with the idea of Native American education. He was increasingly convinced that educating Native Americans was futile (several of his students had failed to conform to his confusing and contradictory standards), and, in late 1768, he lost his connection to the Haudenosaunee. With his inclination and ability to sponsor Native American missionaries largely depleted, Wheelock sought instead to fulfill his ultimate ambition of obtaining a charter and opening a college, which he did in 1769. To fund this new enterprise, Wheelock drew on the £12,000 that Samson Occom had raised for Moor’s Indian Charity School during a two-and-a-half year tour of Great Britain (1765 to 1768). Much of this money went towards clearing land and erecting buildings in New Hampshire for the Charity School’s relocation — infrastructure that also happened to benefit Dartmouth. Many of Wheelock’s contemporaries were outraged by what they saw as misuse of the money, as it was clear that Dartmouth College was not intended for Indians and that Moor’s had become a side project. Although Wheelock tried to maintain at least some commitment to Native American education by recruiting students from Canadian communities, the move did a great deal of damage to his public image. The last decade of Wheelock’s life was not easy. In addition to the problems of trying to set up a college far away from any Anglo-American urban center, Wheelock experienced the loss of relationships with two of his most famous and successful students, Samson Occom and Samuel Kirkland (an Anglo-American protégé). He also went into debt for Dartmouth College, especially after the fund raised in Britain was exhausted.

Samson Occom was a Mohegan leader and ordained Presbyterian minister. Occom began his public career in 1742, when he was chosen as a tribal counselor to Ben Uncas II. The following year, he sought out Eleazar Wheelock, a young Anglo-American minister in Lebanon, CT, in hopes of obtaining some education and becoming a teacher at Mohegan. Wheelock agreed to take on Occom as a student, and though Occom had anticipated staying for a few weeks or months, he remained with Wheelock for four years. Occom’s academic success inspired Wheelock to open Moor’s Indian Charity School in 1754, a project which gave him the financial and political capital to establish Dartmouth College in 1769. After his time with Wheelock, Occom embarked on a 12-year mission to the Montauk of Long Island (1749-1761). He married a Montauk woman, Mary Fowler, and served as both teacher and missionary to the Montauk and nearby Shinnecock, although he was grievously underpaid for his services. Occom conducted two brief missions to the Oneida in 1761 and 1762 before embarking on one of the defining journeys of his career: a fundraising tour of Great Britain that lasted from 1765 to 1768. During this journey, undertaken on behalf of Moor’s Indian Charity School, Occom raised £12,000 (an enormous and unanticpated amount that translates roughly to more than two-million dollars), and won wide acclaim for his preaching and comportment. Upon his return to Mohegan in 1768, Occom discovered that Wheelock had failed to adequately care for his family while he was gone. Additionally, despite the vast sums of money that he had raised, Occom found himself unemployed. Wheelock tried to find Occom a missionary position, but Occom was in poor health and disinclined to leave his family again after seeing the treatment with which they had met while he was in Britain. Occom and Wheelock’s relationship continued to sour as it became apparent to Occom that the money he had labored to raise would be going towards infrastructure at Dartmouth College, Wheelock’s new project, rather than the education of Native Americans. After the dissolution of his relationship with Wheelock, Occom became increasingly focused on the needs of the Mohegan community and increasingly vocal in criticizing Anglo-Americans’ un-Christian treatment of Native Americans. In September of 1772, he delivered his famous “Sermon on the Execution of Moses Paul,” which took Anglo-American spiritual hypocrisy as one of its major themes, and which went into four printings before the end of the year. In 1773, Occom became further disillusioned when the Mason Land Case was decided in favor of the Colony of Connecticut. The details of the Mason Case are complicated, but to summarize: the Colony of Connecticut had gained control of Mohegan land early in the 18th century under very suspect circumstances, and successfully fended off the Mohegan’s 70-year-long legal challenge. The conclusion of the case came as a blow to the Mohegans, and further convinced Occom of Anglo-American corruption. Along with David Fowler (Montauk Tribe), Occom's brother-in-law, and Joseph Johnson (Mohegan), Occom's son-in-law, Occom helped found Brothertown, an Indian tribe formed from the Christian Mohegans, Pequots, Narragansetts, Montauks, Tunxis, and Niantics. They eventually settled in Oneida country in upstate New York. Occom moved there with his family in 1789, spending the remaining years of his life serving as a minster to the Brothertown, Stockbridge, and Mohegan Indians. Harried by corrupt land agents, the Brothertown and Stockbridge groups relocated to the eastern shore of Lake Winnebago, though Occom died in 1792 before he could remove himself and his family there. Occom's writings and legacy have made him one of the best known and most eminent Native Americans of the 18th century and beyond.
