Yale University is a private Ivy League research university in New Haven, Connecticut, United States. Founded in 1701, Yale is the third-oldest institution of higher education in the United States. It is one of the nine colonial colleges chartered before the American Revolution.
Yale was established as the Collegiate School in 1701 by Congregationalist clergy of the Connecticut Colony. Originally focused on theology and sacred languages, the school's curriculum expanded to include humanities and sciences by the time of the American Revolution. In the 19th century, the college expanded to include graduate and professional instruction, awarding the first PhD in the United States in 1861 and organizing as a university in 1887. It is one of the founding members of the Association of American Universities. Yale's faculty and student populations grew rapidly after 1890 due to the expansion of the physical campus and its scientific research programs.
Yale is organized into fifteen constituent schools, including the original undergraduate college, the Yale Graduate School of Arts and Sciences, and Yale Law School. While the university is governed by the Yale Corporation, each school's faculty oversees its curriculum and degree programs. In addition to a central campus in downtown New Haven, the university owns athletic facilities in western New Haven, a campus in West Haven, and forests and nature preserves throughout New England. As of 2025, Yale's endowment was valued at $44.1 billion, making it the second-largest among all educational institutions and the second-largest among private universities. The Yale University Library, serving all constituent schools, holds more than 15 million volumes and is the third-largest academic library in the United States. Student athletes compete in intercollegiate sports as the Yale Bulldogs in the NCAA Division I Ivy League conference.
As of October 2025, 72 Nobel laureates, 5 Fields medalists, 4 Abel Prize laureates, and 3 Turing Award winners have been affiliated with Yale University. Yale alumni include 5 U.S. presidents, 10 Founding Fathers, 19 U.S. Supreme Court justices, 31 living billionaires, 54 college founders and presidents, as well as numerous heads of state, cabinet members, and governors. The university’s community also includes hundreds of members of Congress, U.S. diplomats, 99 MacArthur Fellows, 263 Rhodes Scholars, 123 Marshall Scholars, 81 Gates Cambridge Scholars, 102 Guggenheim Fellows, and 9 Mitchell Scholars. Current Yale faculty include 73 members of the National Academy of Sciences, 55 members of the National Academy of Medicine, 8 members of the National Academy of Engineering, and 200 members of the American Academy of Arts and Sciences. The university is also one of the largest producers of Oscar, Emmy, and Grammy winners. Over 200 Yale alumni have competed in the Olympic games and have won over 110 medals (including 55 gold).
Yale traces its beginnings to "An Act for Liberty to Erect a Collegiate School", a would-be charter passed in New Haven by the General Court of the Colony of Connecticut on October 9, 1701. The act aimed to establish an institution for the education of ministers and lay leaders. Soon after, a group of ten Congregational ministers, Samuel Andrew, Thomas Buckingham, Israel Chauncy, Samuel Mather (nephew of Increase Mather), the Rev. James Noyes II (son of James Noyes), James Pierpont, Abraham Pierson, Noadiah Russell, Joseph Webb, and Timothy Woodbridge, all Harvard alumni, met in the study of the Reverend Samuel Russell, in Branford, to donate books to form the school's library. The group, led by James Pierpont, is now known as the "Founders".
Known from its origin as the "Collegiate School", the institution opened in the home of its first rector, Abraham Pierson, who is considered Yale's first president. Pierson lived in Killingworth. In 1702, Nathaniel Chauncey became the first person to attain a degree, having it conferred solely by oral examination by Pierson and Russell. The school moved to Saybrook in 1707 after Pierson's death, when the first treasurer of Yale, Nathaniel Lynde, donated land and a building. Although the deed required the school to remain in Saybrook, the trustees voted in 1716 to move it to New Haven, which had outbid several other communities for the right to host it.
Meanwhile, there was a rift forming at Harvard between its sixth president, Increase Mather, and the rest of the Harvard clergy, whom Mather viewed as increasingly liberal, ecclesiastically lax, and overly broad in Church polity. The feud caused the Mathers to champion the Collegiate School in the hope it would maintain the Puritan religious orthodoxy in a way Harvard had not. The Reverend Jason Haven, minister at the First Church and Parish in Dedham, Massachusetts, had been considered for the presidency on account of his orthodox theology and "Neatness dignity and purity of Style [which] surpass those of all that have been mentioned", but was passed over due to his "very Valetudinary and infirm State of Health".
In 1718, at the behest of either Rector Samuel Andrew or the colony's Governor Gurdon Saltonstall, Cotton Mather contacted the Boston-born businessman Elihu Yale to ask for money to construct a new building for the college. Through the persuasion of Jeremiah Dummer, Yale, who had made a fortune in Madras while working for the East India Company as the first president of Fort St. George, donated nine bales of goods, which were sold for more than £560, a substantial sum of money. Cotton Mather suggested the school change its name to "Yale College".
Meanwhile, a Harvard graduate working in England convinced 180 prominent intellectuals to donate books to Yale. The 1714 shipment of 500 books represented the best of modern English literature, science, philosophy and theology. It had a profound effect on intellectuals at Yale. Undergraduate Jonathan Edwards discovered John Locke's works and developed his "new divinity". In 1722, the rector and six friends, who had a study group to discuss the new ideas, announced they had given up Calvinism, become Arminians, and joined the Church of England. They were ordained in England and returned to the colonies as missionaries for the Anglican faith. Thomas Clapp became president in 1745, and while he attempted to return the college to Calvinist orthodoxy, did not close the library. Other students found Deist books in the library.
Yale College undergraduates follow a liberal arts curriculum with departmental majors and is organized into a social system of residential colleges.
Yale was swept up by the great intellectual movements of the period—the Great Awakening and Enlightenment—due to the religious and scientific interests of presidents Thomas Clap and Ezra Stiles. They were instrumental in developing the scientific curriculum while dealing with wars, student tumults, graffiti, "irrelevance" of curricula, desperate need for endowment and disagreements with the Connecticut legislature.
Serious American students of theology and divinity, particularly in New England, regarded Hebrew as a classical language, along with Greek and Latin, and essential for study of the Hebrew Bible (Tanakh) in the original. The Reverend Mr. Stiles, president from 1778 to 1795, brought with him his interest in Hebrew as a vehicle for studying ancient Biblical texts in their original language, requiring all freshmen to study Hebrew (in contrast to Harvard, where only upperclassmen were required to study it) and is responsible for the Hebrew phrase אורים ותמים (Urim and Thummim) on the Yale seal. A 1746 graduate of Yale, Stiles came to the college with experience in education, having played an integral role in founding Brown University. Stiles' greatest challenge occurred in 1779 when British forces occupied New Haven and threatened to raze the college. However, Yale graduate Edmund Fanning, secretary to the British general in command of the occupation, intervened and the college was saved. In 1803, Fanning was granted an honorary degree LL.D.
