Chanku Mahato was a freedom fighter of British India coming from Kudmi Mahato community. Chanku Mahto was born in 9 February 1816 in Rangamatia village, Godda district, British India. He was a leader in the Santhal revolt, which mobilized Mahatos to fight against British brutality.
During the Santhal revolt, Chanku Mahato organised a number of movements to resist the British. According to Ranabir Samaddar, in addition to the Santhals, other aboriginal residents of the region, such as Mahatos, Kamars, Bagdis, Bagals, and others, took part in the insurrection. The Mahatos took part under the leadership of Chanku Mahato.
The legend surrounding the Santhal rebellion goes like this:
“Sidhu Kanu khurkhurir upare, Chand-Vairab lahare lahare; Chanku Mahato, Rama Gope lahare lahare, Challu Jolha lahare lahare.“
His slogan was:
“Aapon mati, Aapon dana, Pet kati nihi debo khajna.“
