left the Malankara Orthodox Syrian Church and came into communion with the Catholic Church. They are known as Syro-Malankara Catholic Church. On 11 June 1932, Trivandrum was recognised as a Metropolitan See sui juris, with Thiruvalla as its suffragan. On 10 February 2005, the church was raised to the status of a Major archiepiscopal church. The canonical installation of Cyril Baselios as the first Major Archbishop took place on 14 May 2005 and simultaneously the title 'Catholicos' was legitimized. The St. Ephrem Ecumenical Research Institute (SEERI), inaugurated on 14 September 1985, comes under the Syro-Malankara Catholic Archbishop of Thiruvalla. In 1961, there was a split in the Malankara Mar Thoma Syrian Church which resulted in the formation of St. Thomas Evangelical Church of India.Thomas, K.T. & Rev. T.N. Koshy. Faith on Trial. Ernakulam. 1965. Pentecostalism began to spread among Saint Thomas Christians from 1911, due to American missionary work. The first Syrian Pentecostals came from Kerala Brethren, who were in turn mostly ex-Marthomites. As the movement gained momentum, groups of people from all traditional St. Thomas Christian denominations became part of various emerging Pentecostal and evangelical fellowships. Pentecostals from Syrian Christian background spearheaded the movement in Kerala and to a lesser extent in India, by providing the necessary leadership for establishing denominations like Indian Pentecostal Church of God, Assemblies of God in India, Church of God (Full Gospel) in India, The Pentecostal Mission and many other Neo-charismatic churches. The Syro-Malabar Church too has a very active Charismatic ministry, operated through establishments such as the Divine Retreat Centre, Muringoor. Involvement in politics Participation based on caste and community divisions and sympathies has been a feature of politics in the present day state of Kerala and its predecessor entities. Until the mid-20th century the primary cause of the divisions between the various communities was competition for rights and resources. Like other communities, Saint Thomas Christians have been involved in regional politics on a community basis. In 1888, Travancore became the first princely state in India to establish a Legislative Council, which was reformed as the Sree Moolam Popular Assembly in 1904. A few Saint Thomas Christian leaders were elected to the Legislative Council but there was resentment that their share of the available seats was proportionately less than that of other prominent castes. This resentment led to a series of campaigns for equal representation both in the legislature and in government positions.
