Where did the slide guitar come from

Slide guitar is a form of technique linked with blues music. It was during the 20th century that this technique developed among blues musicians in the American South. There are also links of its origin to the diddley-bow from Africa. However, it was also almost the same time when the Hawaiian (steel) guitar-a style that emerged in the late 19th century but executed a similar slide technique-was gaining popularity on the mainland through Hawaiin concert tours. In conclusion, it is likely that both blues music and Hawaiian guitar paved their own way to become influential in the course of their early development.
