[1] Sardar was born into a Bhumij tribal family on 23 August 1968 in Kundru Tola, Bunudih, Harina, Potka.
[3] In the 2014 elections, the central leadership of JMM did not give ticket to Amulya Sardar, due to which he left the party in dismay.
Contesting as an independent (on diesel pump symbol) from Potka assembly constituency, he could not even save his deposit in this election.
Former JMM MLA Amulya Sardar died of cardiac arrest at his residence in Potka block of East Singhbhum district on 1 March 2017, at the age of 49.
Many prominent people including former Jharkhand Chief Minister Raghuvar Das have expressed grief over his death.
JMM Senior Vice-President Champai Soren, who visited Sardar's home to pay his homage, said he played a major role in the statehood movement of Jharkhand.
Soren said Sardar's death was an irreparable loss to the party as he was instrumental in increasing JMM's base in rural pockets of East Singhbhum district.
