Can I know which was the First Kannada Kingdom?

Answer 1

Around 230 BCE, the Satavahana dynasty came to power and its rule lasted nearly four centuries till the early 3rd century CE. The disintegration of the Satavahana dynasty led to the ascent of the earliest native kingdoms, the Kadamba Dynasty of Banavasi in modern Uttara Kannada district with Mayurasharma, a brahmin native of Talagunda in modern Shivamogga district as the founding king, and the Western Ganga Dynasty in southern Karnataka, marking the birth of the region as an independent political entity.

These were the first kingdoms to give administrative status to Kannada language as evidenced by the Halmidi inscription of 450, attributed to King Kakusthavarma of the Kadamba Dynasty.

Also, recent discovery of a 5th century copper coin in Banavasi, ancient capital of the Kadambas, with Kannada script inscription on it, further proves the usage of Kannada at an official level.
