No one knows the exact period of Karate's development. Yet, it is a continuous process. There are many branches of Karate and some more sub-branches. New styles of Karate are being developed each year. I think, originally karate came from Chinese Martial Arts (maybe Kung-fu and Kung-fu ages back to Ancient History- Rise of Buddhism).
So, I think Karate's development is a topic of Research and just out of the scope of this answer.
