Old Kannada or Halegannada is the Kannada language which transformed from Purvada halegannada or Pre-old Kannada during the reign of the Kadambas of Banavasi (ancient royal dynasty of Karnataka 345−525 CE). The Modern Kannada language has evolved in four phases over the years. From the Purva Halegannada in the 5th century (as per early epigraphic records), to the Halegannada (Old Kannada) between the 9th and 11th century, the Nadugannada (Middle Kannada) between the 12th and 17th century (as evidenced by Vachana literature), it has evolved to the present day Hosagannada (Modern Kannada) from 18th century to present. Hosagannada (Modern Kannada) is the official language of the state of Karnataka and is one of the 22 official national languages of the Republic of India and is the native language of approximately 65% of Karnataka's population.
