Principia College (commonly referred to as Principia or Prin) is a private liberal arts college in Elsah, Illinois, United States. A four-year coeducational institution, the college was founded in 1912 by Mary Kimball Morgan, and its stated purpose is "to serve the Cause of Christian Science." According to the college, it has no affiliation with the Church of Christ, Scientist, but "the practice of Christian Science is the cornerstone of campus life." Students and staff are practicing Christian Scientists.
Principia College campus sits on bluffs overlooking the Mississippi River between Alton and Grafton. The campus is located on rural total of 2,500 acres (10 km2) acres in the Metro East region of Southern Illinois, thirty miles north of St. Louis.
Principia College was born out of The Principia, founded by Mary Kimball Morgan in 1897, though the name Principia was not adopted until the year 1898. As Morgan's school grew, founder of Christian Science, Mary Baker Eddy approved The Principia's reference as a Christian Science school. Emerging from the Principia Lower, Middle, and Upper Schools founded between 1898 and 1906, Principia College was established with a purpose of "serving the Cause of Christian Science through appropriate channels open to it as an educational institution." The college, however, has no official affiliation with the Christian Science Church and Christian Science is not taught as a subject, but its principles form the basis of community life at Principia. The first Upper School class graduated in 1906 and it is from this class that a junior college was established, whose first alumni graduated in 1917. Following this time period architect Bernard Maybeck was commissioned to design a new college campus in Elsah, Illinois and by 1931 ground was broke on what would become Maybeck's largest commission.
In 1934, Principia College graduated its first class as a full four-year institution and in 1935 the college was officially moved to its present-day location in Elsah. On April 19, 1993, the campus was designated a National Historic Landmark by the United States Department of the Interior. The year 1998 marked centennial celebrations by the school. The Principia College campus was once considered as the site for the United States Air Force Academy though ultimately the Air Force chose a location in Colorado Springs, Colorado instead.
Principia College offers twenty-seven majors in the liberal arts and sciences. The college does not currently offer a graduate program though graduates of the college later attend institutions such as Boston University, George Mason University, Georgetown University, Harvard University, Northwestern University, Pepperdine University, Purdue University, Stanford University, University of California, Berkeley, University of Chicago, University of Michigan and Yale University among others. The most popular majors at this Illinois college include mass communication, biology, sociology, anthropology, studio and fine art, and business administration.
In 2009, Forbes rated it 57th of America's Best Colleges. In 2014, U.S. News and World Report ranked Principia College #139 in the National Liberal Arts Colleges. As of 2014, Principia College's annual tuition costs were $26,850. The school has an acceptance rate above 80%. 
Housing and student life facilities
There are ten student dormitories on campus: Anderson House, Rackham Court, Howard House, Sylvester House, Buck House, Brooks House, Ferguson House, Joe McNabb, Lowrey House, and Clara McNabb. The first six mentioned were designed by former University of California, Berkeley professor and AIA Gold Medal winner Bernard Maybeck in 1935, as was the campus' chapel. Maybeck attempted to use different architectural styles and building techniques for each of these dormitories and for the chapel. In an effort to ensure success with his designs and materials, he experimented with them through the creation of a small building known affectionately by Principians as the "Mistake House."
Principia College has a diverse student composition and amount of organizations given its size. 20% of its students are international and represent thirty countries on six of the world's seven continents. The college has forty student clubs and organizations, among these the Euphrates and Leadership institutes.

Bush, former United States president Jimmy Carter, American author and poet Maya Angelou, David McCullough, Elie Wiesel, American actor and director Robert Duvall, Val Kilmer, Coretta Scott King, and Margaret Thatcher among others.
