Kansai dialect
The Kansai dialect has over a thousand years of history. When Kinai cities such as Nara and Kyoto were Imperial capitals, the Kinai dialect, the ancestor of the Kansai dialect, was the "de facto" standard Japanese. It had an influence on all of the nation including the Edo dialect, the predecessor of modern Tokyo dialect. The literature style developed by the intelligentsia in Heian-kyō became the model of Classical Japanese language.
