Kamehameha Schools, formerly called Kamehameha Schools Bishop Estate (KSBE), is a private school system in Hawaiʻi established by the Bernice Pauahi Bishop Estate, under the terms of the will of Princess Bernice Pauahi Bishop, who was a formal member of the House of Kamehameha. Bishop's will established a trust called the "Bernice Pauahi Bishop Estate" that is Hawaiʻi's largest private landowner. Originally established in 1887 as an all-boys school for native Hawaiian children, it shared its grounds with the Bishop Museum. After it moved to another location, the museum took over two school halls. Kamehameha Schools opened its girls' school in 1894. It became coeducational in 1965. The 600-acre (2.4 km2) Kapālama campus opened in 1931, while the Maui and Hawaiʻi campuses opened in 1996 and 2001, respectively.
