suffered a large fire that destroyed its interior in 1802, which Smith blamed on rebellious students. The college raised funds for reconstruction, as well as the construction of two new buildings. In 1807, a large student riot occurred at Nassau Hall, spurred by underlying distrust of educational reforms by Smith away from the Church. Following Smith's mishandling of the situation, falling enrollment, and faculty resignations, the trustees of the university offered resignation to Smith, which he accepted. In 1812, Ashbel Green was unanimously elected by the trustees of the College to become the eighth president. After the liberal tenure of Smith, Green represented the conservative "Old Side," in which he introduced rigorous disciplinary rules and heavily embraced religion. Even so, believing the College was not religious enough, he took a prominent role in establishing the Princeton Theological Seminary next door. While student riots were a frequent occurrence during Green's tenure, enrollment did increase under his administration. In 1823, James Carnahan became president, arriving as an unprepared and timid leader. With the college riven by conflicting views between students, faculty, and trustees, and enrollment hitting its lowest in years, Carnahan considered closing the university. Carnahan's successor, John Maclean Jr., who was only a professor at the time, recommended saving the university with the help of alumni; as a result, Princeton's alumni association, led by James Madison, was created and began raising funds. With Carnahan and Maclean, now vice-president, working as partners, enrollment and faculty increased, tensions decreased, and the college campus expanded. Maclean took over the presidency in 1854 and led the university through the American Civil War. When Nassau Hall burned down again in 1855, Maclean raised funds and used the money to rebuild Nassau Hall and run the university on an austerity budget during the war years. With a third of students from the college being from the South, enrollment fell. Once many of the Southerners left, the campus became a sharp proponent for the Union, even bestowing an honorary degree to President Lincoln.James McCosh became the college's president in 1868 and lifted the institution out of a low period that had been brought about by the war. During his two decades of service, he overhauled the curriculum, oversaw an expansion of inquiry into the sciences, recruited distinguished faculty, and supervised the addition of a number of buildings in the High Victorian Gothic style to the campus.
