Is Japanese Katakana Derived from Korean Kwukyel?
The Gugyeol script is said to be from the Shilla period in Korean history. The earliest remnants of it found in Korea thus far date from the 11th Century. So there is a which came first argument because of the chronological difference between the Japanese 9th Century records of Katakana and the later Korean historical evidence of Gugyeol that has survived. I put a link to a shorter Korean video on this subject just so the similarities in the scripts and there initial common source in traditional Chinese characters can be visualized. The video is in Korean but it has some charts or graphics which show the Gugyeol and Katakana and some of the hanja/kanji they are both related to. The relevant graphics begin to appear at about 2:32.
The video was based on a work by linguist Alexander Vovin. It's remarkable how similar the characters are. This ancient Korean script apparently fell out of use even by scholars and monks in Korea by the 19th Century. This was a big revelation to me, I had never heard of this earlier Korean writing system. It's fairly obscure. At the link below is Volvin's article explaining his theory of the connection between Gugeol and Katagana.

(3,306 posts)from Korea. Prince Im Sung. He had to leave the Baekje kingdom or risk being killed in a series of frequent dynastic succession struggles. He took a particular sect of Buddhism with him, metallurgists, along with a variety of Korean wares, artwork, architecture, etc.. Archeologists found this his cultural footprint extended all over the prefecture in a short time because he was a very successful merchant trader with Korea. I should have taken notes or saved the link. His Japanese descendants maintained an ancestry record which went all the way back to his arrival in Japan. There is even a myth in the region where he landed about an astrological event which heralded the Prince's arrival.
While there has been a history of piracy, the Japanese Imjin invasion didn't take place until 1592. (King Sejong's hangul alphabet was completed by 1446. I've had some people say to me they think hangul came from Japanese script which is an unsupportable contention). Massive looting and pillaging took place in the 1590s, and then again in the latter 19th Century up through 1945 but those events were much later.
