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.

New London is a city located in southeastern Connecticut along an estuary of the Atlantic Ocean called Long Island Sound. The area that would become New London was inhabited by the Pequots who called it Nameaug when the Europeans arrived in North America. Pequot villages bordered Long Island Sound and the Tribe had authority over the neighboring Tribes of the Mohegans and Niantics (all Algonquian-speaking tribes). The Dutch first explored this land in 1614 and established trade with the Native peoples, but the English soon gained possession of the land east of the Hudson in the 1630s. English animosity toward their Indian neighbors led to the Pequot War (1634-38), part of which took place in the present city of New London. The Pequots lost the war and their population deteriorated due to the violence and disease. The General Court of Massachusetts granted John Winthrop possession of Pequot territory in 1644 after which it was to be opened for settlement. By 1646, which is considered the official year of its founding, New London had permanent colonial inhabitants and municipal laws, and jurisdiction was granted to the colony of Connecticut in 1647. In 1658, the inhabitants renamed the town New London after London, England. New London was the colony of Connecticut’s first trading port and was a hub of trade with the West Indies and other colonies. Though initially part of the town of New London when it was first settled by the colonists, Groton, Montville, and Waterford were each separated from New London in 1705, 1786, and 1801 respectively. Present-day Salem was also part of New London when it was settled, but in 1819, it became a separate incorporated town composed of parts of Lyme, Colchester, and Montville. Occom kept a school in New London in the winter in 1748. New London was the home of Captain Nathaniel Shaw, one of the wealthiest merchants in the area, who gave money to Occom in the 1750s for the missionary cause and also sold materials to Occom for the building of his home. However, their positive relationship ended when Shaw refused to provide supplies for Mary Occom while Occom was in England. New London served as the port from which Occom and other missionaries traveled to reach Long Island. During the American Revolution, New London’s location and its status as a seaport made it both vulnerable to invasion and integral to colonial naval operations as well as the exchange of prisoners.New London was incorporated as a city in 1784.

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.

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.

Mary Occom (née Fowler) was a Montaukett woman who married Samson Occom. Although information about her is limited and often comes from male, Anglo-American sources, it offers a tantalizing glimpse of her strength, as well as an alternative to the Eleazar Wheelock-centered narrative of Occom’s life that often dominates the latter’s biography. Mary was born into the influential Fowler family at Montauk, Long Island. She met Samson during his missionary service there (1749-1761). Mary studied at Samson’s school along with her brothers David and Jacob, and was almost certainly literate. She and Samson married in 1751. Wheelock and several other Anglo-American powers opposed their union because they worried it might distract Occom from being a missionary (as, indeed, family life did), and thus many scholars have read in Samson and Mary’s marriage an act of resistance against Samson’s domineering former teacher. Little information about the minutiae of Mary’s life survives, but existing sources speak volumes about her character and priorities. In front of Anglo-American missionaries visiting the Occoms' English-style house at Mohegan, Mary would insist on wearing Montaukett garb and, when Samson spoke to her in English, she would only reply in Montaukett, despite the fact that she was fluent in English. Mary Occom was, in many ways, Wheelock’s worst fear: that his carefully groomed male students would marry un-Anglicized Indian women. It is not a stretch to imagine that Mary provided much of the incentive for Wheelock to begin taking Indian girls into his school, lest his other protégés replicate Samson’s choice. Much of our information about Mary comes from between 1765 and 1768, when Samson was fundraising in Great Britain. Despite promising to care for Samson’s wife and family (at the time they had seven children), Wheelock, by every objective measure, failed to do so, and Mary’s complaints are well documented. Hilary Wyss reads in Wheelock’s neglect (and in letters from the time) a more sinister story, and concludes that on some level Wheelock was holding Samson’s family hostage, in return for Occom curtailing his political beliefs on the Mason Case. Wyss also notes Mary’s remarkable survivance in this situation. Mary drew on various modes of contact, from letters to verbal communication with influential women (including Sarah Whitaker, the wife of Samson’s traveling companion, and Wheelock’s own daughters), to shame Wheelock into action and demand what she needed. One of the major struggles in Mary’s life, and in Samson’s, was with their sons. Both Aaron and Benoni failed to live up to their parents’ expectations. Aaron attended, and left, Moor’s Indian Charity School three times, and both Aaron and Benoni struggled with alcohol and refused to settle down. The Occom daughters did not cause similar problems. Given the nature of existing sources, little is known about Mary after Samson and Wheelock lessened their communication in 1771. Joanna Brooks has conjectured that Mary was likely influential in Samson’s Mohegan community involvement later in life, for instance, in his continued ministry to Mohegan and, perhaps, his increasingly vehement rejection of Anglo-American colonial practices.

Elizabeth (Betty) Fowler was an influential Montauk woman and the mother of Mary Fowler Occom, David Fowler, and Jacob Fowler. She was a member of the powerful Pharaoh/Faro family, a family which boasts the current (as of 2013) Montaukett sachem. Elizabeth was married to James Fowler. Occom married their daughter Mary, and as a result the Fowler family received extra attention from the minister and became deeply Christian. James Fowler died in 1774, but Elizabeth lived until 1795. She migrated to Brothertown with Mary, David, and Jacob, where she died sometime after 1795.
