Ayyankali (also Ayyan Kali) (28 August 1863 – 1941) was a social reformer who worked for the advancement of those people in the 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 vellayambalam square in Thiruvananthapuram.
Later in 28 August 2019, Kerala Chief minister Pinarayi Vijayan announced that the historic Victoria Jubilee Town Hall in Thiruvananthapuram, popularly known as VJT Hall, would be renamed after social reformer Mahatma Ayyankali.
