Travancore and Cochin, from responsible government to their merger, with Malabar still in Madras

Background

Kerala Piravi falls at the start of November, and the nine years before the State was formed are what the day actually commemorates.
On 4 September 1947 the Maharaja of Travancore announced the move to establish a responsible Government, and a new Assembly called the Representative Body was to function as the Constituent Assembly, with 120 members elected on adult franchise.
That Assembly first sat on 20 March 1948 under President A. J. John, and the Travancore Interim Constitution Act promulgated on 24 March 1948 provided a Council of Ministers headed by a Prime Minister and responsible to the Assembly, with the Maharaja as Constitutional Head.
Pattom A. Thanu Pillai served as Prime Minister from 24 March 1948, and T. K. Narayana Pillai succeeded him in October that year.
Responsible Government in Cochin took form on 14 August 1947 with Panampilly Govinda Menon as its first Prime Minister, the Legislative Council was renamed the Legislative Assembly, and a popular Ministry headed by Ikkanda Warrier came to power on 20 September 1948.
The merger of Travancore and Cochin was realised on 1 July 1949, the Maharaja of Travancore became the Rajapramukh of the new Travancore-Cochin State, and its First Legislative Assembly was composed of 178 members drawn from the two legislatures.
T. K. Narayana Pillai became Chief Minister of the new State and T. M. Varghese its Speaker, and 71 bills were passed in 7 sessions.
Malabar, a district of Madras Province, stayed outside: it had 16 members in the First Madras Legislative Assembly, 20 in the Second, and 29 after the first general elections held under the Constitution of India.
