What is "ayyankali"

Ayyankali (also Ayyan Kali) (28 August 1863 – 1941) was a social reformer who worked for the advancement of those people in the then princely state of Travancore, British India, who were treated as untouchables. His efforts influenced many changes that improved the social wellbeing of those people, who are today often referred to as Dalits.

In November 1980, Indira Gandhi unveiled a statue of Ayyankali at Kowdiar square in Thiruvananthapuram.
