Uttara Kannada district was a part of Bombay Presidency during the British rule. Before reorganization of the States, the district was in Bombay State. The local Konkani-speaking people had close connections with Mumbai then. They had matrimonial relations also with the people in Bombay. Many Marathi-medium schools had also been established in Karwar and Joida taluks. Marathi films were released often in Karwar. The visit of Marathi drama troupes from Mumbai and Pune was an annual feature. However, Konkani-speaking people were disenchanted when Marathis began to claim that Konkani was a dialect of Marathi. They disputed it and asserted that Konkani had independent status as a language. It was the Konkani-speaking people led by late P.S. Kamat who argued before Mahajan Commission that Karwar was an integral part of Karnataka, which is upheld by the historical context too.
