Whitman College is a private liberal arts college located in Walla Walla, Washington. Initially founded as a seminary by a territorial legislative charter in 1859, the school became a four-year degree-granting institution in 1883. In 1859, soon after the United States military declared that the land east of the Cascade Mountains was open for settlement by American pioneers, Cushing Eells traveled from the Willamette Valley to Waiilatpu, near present-day Walla Walla, where 12 years earlier, Christian missionaries Dr. Marcus Whitman and Narcissa Whitman, along with 12 others were killed by a group of Cayuse Indians during the Whitman Massacre. While at the site, Eells became determined to establish a "monument" to his former missionary colleagues in the form of a school for pioneer boys and girls. Eells obtained a charter for Whitman Seminary, a pre-collegiate school, from the territorial legislature. From the American Board of Commissioners for Foreign Missions, he acquired the Whitman mission site. Eells soon moved to the site with his family and began working to establish Whitman Seminary. Whitman College focuses solely on undergraduate studies in the liberal arts. All students must take a two-semester course their first year, Encounters, which examines cultural interactions throughout history and gives students a grounding in the liberal arts. Students choose from courses in 46 major fields and 32 minor fields and have wide flexibility in designing independent study programs, electing special majors, and participating in internships and study-abroad programs. Whitmans most popular majors are Biology, Psychology and Economics.
