Lebanon is a town located in the state of Connecticut southwest of the town of Hartford. The land that became Lebanon was inhabited at least 10,000 years ago based on the archeological record. By the 1600s, the land was permanently inhabited by the Mohegan Indians, who used the area primarily for hunting. Lebanon was officially formed in 1700 when English settlers consolidated a number of land tracts, including several land grants by the Connecticut General Assembly and lands purchased from the Mohegans. However, these purchases were controversial. In 1659, the Mohegans entrusted their reserve land to Major John Mason, and in the following year, Mason transferred this land to the Connecticut colonial government with the understanding that there would be enough land left for the Mohegans to farm. The Mohegans claimed that they never authorized a transfer to the colonial government and only Mason’s heirs were entrusted with their land. In 1662, Connecticut, which included the Mohegan land that had been entrusted to the Masons, was incorporated by a royal charter. Based on this charter, the colony argued that the land was now the property of the government. In 1687, the colony began granting the Mohegan land to townships, and in 1704 the Masons petitioned the Crown on behalf of the Mohegans, claiming that such transfers of land to townships were illegal. Between the years of 1705 and 1773 legal disputes and controversies persisted, finally ending in a verdict by the Crown against the Mohegans. In 1755, Wheelock received property and housing in Lebanon that he would use as his house and school. While Lebanon was originally incorporated as a part of New London County in 1700, in 1724 it became a part of New Windham, before once again becoming a part of New London County in 1826. Lebanon was central to the American Revolution with half of its adult population fighting for the colonists and hundreds of meetings convened in the town for the revolutionary cause.

Albany is a city located in eastern New York. When Netherlander Henry Hudson arrived in what would become Albany in 1609, the Mohican Indians lived in several villages in the area. The Mohicans gave Hudson’s crew furs, and the Dutch East India Company sent representatives to trade with the Native peoples. The Dutch established the village of Beverwyck within the territory of the New Netherlands. Beverwyck hosted a diverse population of Germans, French, Swedes, English, Irish, Scots, Dutch, and Africans. After the fall of New Netherlands to Britain in 1664, Beverwyck was renamed Albany in honor of the colony’s proprietor James, Duke of York and Albany. In 1686, Albany was granted a charter that incorporated the city and provided it the sole right to negotiate trade with Native Americans. During the French and Indian War, Albany was designated as the British military headquarters in the Americas. During the Revolutionary War, most Albany residents supported the revolution because of their opposition to British trade restrictions.

Oneida is a city in Madison County located at the geographical center of New York state. Before European settlement of the area, the Oneida Tribe, one of the Six Nations of the Haudenosaunee (Iroquois) Confederacy, inhabited a large territory adjacent to nearby Oneida Lake. Around 1533, they built their first village on the south shore of the lake, at or near the mouth of Oneida Creek. At the end of the 17th century, this area began suffering raids by parties from the French colony of Quebec, in a battle to control the fur trade. In 1696, Oneida village was burned by the French. As a result, the Oneidas moved their chief village east of the original site, called Old Oneida, to a new site called Kanawalohale, also known as Oneida Castle, which was fortified by tall palisades and a moat. This is the site of the present-day village of Oneida Castle, a small hamlet west of the city of Oneida in the northwest corner of the town of Vernon. When used in Occom Circle documents, the place name "Oneida" usually refers to the territory inhabited by the Tribe east of Oneida Lake, but can also refer specifically to Oneida Castle. Although the Oneidas sided with the patriots during the Revolutionary War, much of their territory was sold or appropriated by the state of New York. In 1790, the first European settlers moved into the area of Old Oneida village, and the district began to expand. In the 1830s, the state built a feeder from Oneida Creek through the present city site to provide water for the new canal system, which enabled canal boats to ship freight into the town. Eventually, the railroad came through the town and helped with its expansion. This led to the incorporation of the Village of Oneida in 1848 and the establishment of the Town of Oneida in 1896. The town was chartered as the City of Oneida in 1901, and with two more railroad lines transecting the area, it became a thriving manufacturing center for the first half of the 20th century.

The historical Mohawk village of Canajoharie was located about 50 miles northwest of Albany, New York, in the central part of the state. Today, both a town and village in the same vicinity of the Mohawk village of Canajoharie have taken the Mohawk name, but the location of the present-day village is slightly east of the historical village. Because the village’s name was similar to the Oneida village of Kanawalohale, where David Fowler established a school in 1765, many sources conflate the two villages. Canajoharie, which in English means a washed kettle, was also known by the names Indian Castle and Upper Castle, which refers to the late 17th-century Mohawk fortifications that were built around the town following a series of French attacks during King William’s War. The term Upper Castle served to differentiate Canajoharie from Lower Mohawk Castle located in the Mohawk village of Tionondoroge near Fort Hunter. Canajoharie contained the Indian Castle church, which still stands today and was built in 1769 by the British Superintendent of Indian Affairs, Sir William Johnson, with help from the Mohawk siblings Molly and Joseph Brant, who donated land to the cause. Throughout the span of the 18th century, war, disease, and emigration severely reduced the Mohawk population in Canajoharie, and an influx of both white and non-Mohawk Native Americans resulted in a diverse and ethnically mixed culture. Wheelock's missionary work in this village in the 1760s was headed by Theophilus Chamberlain, while Abraham major, Abraham minor, and Peter (Mohawk) maintained missionary schools near Canajoharie.

Theophilus Chamberlain was a Yale graduate and missionary employed by Wheelock. His interest in Indian ministry may have started during the French and Indian War, when he was taken captive by a tribe allied with the French (it is unclear which tribe) at Fort William Henry and spent a year in Nova Scotia. After his return to New England, Chamberlain attended Yale. Wheelock recruited Chamberlain, along with fellow Yale graduate Titus Smith, to spearhead Moor's 1765 mission to the Six Nations. Chamberlain was examined as a missionary on March 12, 1765, and ordained on April 24, 1765. During the mission, he was stationed at Canajoharie (the Mohawk "Upper Castle") and oversaw the mission to the Mohawks. While on his mission, he converted to Sandemanianism, a decision that profoundly shaped the rest of his life. It is difficult to evaluate his efficacy as a missionary: he had high praise for himself, and David Fowler said the Mohawks were affectionate towards him, but Occom described him as overzealous. Chamberlain served the duration of his contract, but clashed with Wheelock afterwards over who was responsible for debts he had incurred on his mission (e.g. transportation costs, support for schoolmasters and interpreters). After departing from Wheelock's service, Chamberlain was ordained as a Sandemanian bishop. He fled to New York and later Nova Scotia during the American Revolution because of his religious and political beliefs. In Nova Scotia, Chamberlain oversaw the establishment of the settlement of Preston.

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.
