Nagalingam Shanmugathasan
Sri Lankan politician (1920–1993)

Nagalingam Shanmugathasan (Tamil: நாகலிங்கம் சண்முகதாசன், 1920 – 8 February 1993) was a trade unionist and Maoist revolutionary leader in Sri Lanka. He was the General Secretary of the Ceylon Communist Party (Maoist)
Early life and family
Shanmugathasan hailed from a family of modest means in the town of Manipay in Jaffna District. He began studying history at the University College Colombo in 1938, where he first came into contact with communist ideas and met supporters of the Communist Party of Great Britain who had returned from studying at Cambridge University. In 1939 he and two fellow students were suspended, but soon reinstated, from the university for distributing anti-imperialist flyers after the outbreak of World War II. Shanmugathasan gained notoriety among the students after this action and in 1940 won in the student election to become General Secretary of the University Union Society. The next year he was elected President of the Society. In the meantime, he was organizing a group of Communists among the students that opposed both British imperialism and the Trotskyists of the Lanka Sama Samaja Party.
After graduating from the University of Ceylon in 1943, Shanmugathasan joined the trade union movement, and became a full-time activist of the Ceylon Communist Party. He became the head of the Ceylon Trade Union Federation and led several strikes, including the general strike of 1947, the Hartal (general strike) of 1953, and a transport strike in 1955.
Shanmugathasan married with Parameswari, the widow wife of veteran Communist leader Hon. Pon Kandiah.

Why this record matters
The phrase “sri Lankan politician (1920–1993)” supplies a clear boundary for inquiry. It also exposes the unanswered questions: who defined that boundary, when it became stable and which sources sit outside it.

The source revision retrieved here is dated Apr 26, 2026. The linked authority identifier is Q3535792. 1 of 1 selected statements include explicit references; 0 carry qualifiers and 0 use preferred rank.

A concise life account rarely captures disputed attribution, private networks or the changing language used to describe a career. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
