Baritsu vs. Bartitsu — What's the Difference?

Baritsu is the name given to a form of martial art described by Sir Arthur Conan Doyle in the 1903 Sherlock Holmes story "The Adventure of the Empty House", the first of The Return of Sherlock Holmes. Baritsu was used to explain how Holmes had managed to avoid falling into the Reichenbach Falls with Professor Moriarty as described in the 1893 story "The Final Problem".

Bartitsu is an eclectic martial art and self-defence method originally developed in England in 1898–1902, combining elements of boxing, jujitsu, cane fighting and French kickboxing (savate). In 1903, it was immortalised (as "baritsu") by Sir Arthur Conan Doyle, author of the Sherlock Holmes mystery stories.
