There were originally three charitable Foundations of the modern Order. One, which became The St John of Jerusalem Eye Hospital Foundation, was established in 1882. The St John Ambulance Association, which was concerned with training the public in first aid, was established in 1877. And, the third was The St John Ambulance Brigade, which provided first aid care to the public. It had its origins in 1873, and became a Foundation in 1887. The St John Ambulance Association and The St John Ambulance Brigade were amalgamated in 1974 to form the present St John Ambulance Foundation.

There was a major re-structuring of the Order’s constitution in 1999. This introduced a new governing body called the Grand Council. The Order today consists of 8 St John national organisations known as Priories, 33 St John national organisations known as Associations and the St John Eye Hospital Group which has its main hospital in Jerusalem.
