Karate began as a fighting system known as te in Okinawa, the Ryu Kyu islands south of Japan. In the 14th century with trade relations with China and Chinese settlers on the islands introduced some Chinese Martial Arts into the community.
Karate developed regionally on the islands, often generalized as Shuri-te, Naha-te, and Tomari-te, named after the three cities from which they emerged. Each area and its teachers had particular kata, techniques, and principles that distinguished their local version of te from the others.
By the 19th century, Itosu Ankō (1831–1915), a student of Matsumura, helped to get karate introduced into Okinawa's public schools. His students became some of the most well-known karate masters, including Gichin Funakoshi, Kenwa Mabuni, and Chōki Motobu. Itosu is sometimes referred to as "the Grandfather of Modern Karate.
Gichin Funakoshi, the founder of Shotokan karate, is generally credited with having introduced and popularized karate on the main islands of Japan. In addition, many Okinawans were actively teaching, and are thus also responsible for the development of karate on the main islands. Funakoshi was a student of both Asato Ankō and Itosu Ankō (who had worked to introduce karate to the Okinawa Prefectural School System in 1902).
Shotokan training is usually divided into three parts: kihon (basics), kata (forms or patterns of moves), and kumite (sparring). Techniques in kihon and kata are characterised by deep, long stances that provide stability, enable powerful movements, and strengthen the legs. Shotokan is regarded as a dynamic martial art as it develops anaerobic, powerful techniques as well as developing speed. Initially strength and power are demonstrated instead of slower, more flowing motions. Those who progress to brown and black belt level develop a much more fluid style that incorporates grappling, throwing and some standing joint locking techniques, which can be found even in basic kata. Kumite (fighting) techniques are practiced in the kihon and kata and developed from basic to advanced levels with an opponent.
