Puchalapalli Sundarayya (born Sundararami Reddy; 1 May 1913 – 19 May 1985), popularly known as Comrade PS, was an Indian Communist leader including of the peasant revolt in the former Hyderabad State of India, called the Telangana Rebellion and he was also one of the founding members of Communist Party of India (Marxist).
Sundarayya was born on 1 May 1913 in Alaganipadu (in the present Vidavalur Mandal of Kovur Constituency) in Nellore district of Andhra Pradesh, India.
He completed primary education and entered a college where he studied at entry level until he left in 1930, at the age of 17, to join Mahatma Gandhi's non-cooperation movement.
He was arrested and spent time in a Borstal school in Rajahmundry where he became acquainted with various communists and local dalit leaders.
He was mentored by Amir Hyder Khan, who prompted him to become a member of the Communist Party of India, which was condemned and banned by the British government during the Second World War.
After the arrest of Amir Hyder Khan, following the directions of the Central Committee, the task of building the Party in South India fell on his shoulders.
In that Congress, the Communist Party of India adopted a line advocating armed struggle, that came to be known as 'Calcutta thesis'.
However, immediately after this conference, Sundarayya and several Party leaders were arrested because of a ruling produced by the Congress government, and they were detained until May 1966.
He went to Parliament on a bicycle at a time when most of the MPs were either zamindars or hailed from aristocratic families who arrived in luxury cars.
