The Rajkumar College (or RKC) in Rajkot is one of the oldest K-12 institutions in India. RKC has a 26 acre (105,000 m²) campus located in the heart of Rajkot city. The foundation stone was laid in 1868 and the college was formally opened in 1870. The college was founded for the education of the Princely order by the Princes and Chiefs of Kathiawad for their sons and relations. The First Forty Years of the Rajkumar College is an account of the origin of the college, prepared and abridged from the papers of Chester Macnaghten, first principal of the college and other sources. It was compiled in seven volumes by Maharaja Bhavsinhji of Bhavnagar, an alumnus, like his father Takhtsinhji and son, Krishna Kumarsinhji. In 1938, on the initiative of its founding members, the college became a Public School (private school in Western terms). The college is a founding member of the Indian Public Schools Conference, and a member of The Round Square Conference of Schools, a worldwide association of more than 60 schools that allows students to travel between schools and tour the country or do community service.
