The East India Company Military Seminary was a British military academy at Addiscombe, Surrey, in what is now the London Borough of Croydon. It was opened in 1809 and closed in 1861. Its purpose was to train young officers to serve in the East India Company’s private army in India.The institution was formally known as the East India Company Military Seminary (a name the cadets always disliked) until 1855, when the name was changed to the East India Company Military College.
