Travancore–Cochin, or Thiru–Kochi, was a short-lived state of India (1949–1956). It was originally called United State of Travancore and Cochin following the merger of two former kingdoms, Travancore and Cochin on 1 July 1949. Its original capital was Thiruvananthapuram. It was renamed State of Travancore–Cochin in January 1950. Travancore merged with erstwhile princely state of Cochin to form Travancore–Cochin in 1950. The five Tamil-majority Taluks of Vilavancode, Kalkulam, Thovalai, Agastheeswaram, and Sengottai were transferred from Travancore-Cochin to Madras State in 1956. The Malayalam-speaking regions of the Travancore–Cochin merged with the Malabar District (excluding Laccadive & Minicoy Islands) and the Kasaragod Taluk of South Canara district in Madras State to form the modern Malayalam-state of Kerala on 1 November 1956, according to the States Reorganisation Act, 1956 passed by the Government of India. History Paravur T. K. Narayana Pillai, the Congress Prime Minister of Travancore, became the Chief Minister of Travancore–Cochin. First elections were held in 1951 and A. J. John, Anaparambil from Congress party was elected as the Chief Minister, ruling until 1954. The ruler of Travancore was appointed as the governor (known as "Rajpramukh") of Travancore–Cochin. The Maharajah of Cochin was offered to be addressed as Uparaja Pramukh, but he did not want any title after handing over the power. The Maharaja politely said that the eldest member of Cochin Royal Family should be called Valiya Thampuran and gave up royal powers unconditionally for the good of the people. While Pattom A. Thanu Pillai was the Praja Socialist Party Chief minister in 1954, Travancore Tamil Nadu Congress launched a campaign for the merger of the Tamil-speaking regions of Southern Travancore with the neighbouring area of Madras State. The agitation took a violent turn and civilians and local police were killed at Marthandam and Puthukkada, irreparably alienating the entire Tamil-speaking population from merger into Travancore–Cochin. Under State Reorganisation Act of 1956, the four southern taluks of Travancore, namely Thovalai, Agasteeswaram, Kalkulam and Vilavancode and a part of the Chencotta, Tenkasi Taluk was merged with Madras State. On 1 November 1956 Travancore–Cochin was joined with Malabar District of Madras State to form the new state of Kerala, with a governor, appointed by the President of India, as the head of the state instead of 'Rajapramukh'. Merger of Kanyakumari with Madras State Tamils lived in large numbers in the Thovalai, Agastheeswaram, Sengottai, Eraniel, Vilavancode, Kalkulam, Devikulam, Neyyattinkara, Thiruvananthapuram South and Thiruvananthapuram North
