12. Thaliyil Madhavan Pillai

This name was suggested by Kappana Kannan Menon (Thalassery) who was then the Headmaster of St. Berkmen High School Changanacherry wherein K. Kelappan Nair was also a teacher. This name was chosen in the beginning in the model of SERVANTS OF INDIA SOCIETY that was prevalent in those days under the stewardship of Gopalakrishna Gokhale and N.M. Dravid,G,K. Devdhar, A.V. Patwardhan, Ranade like veterans on national level.

In his childhood, the great personality influenced Mannath Padmanabhan in social movements was the eminent Lawyer Govinda Pillai of Kainikara house that was situated adjacent to Chiramuttam and Mannath houses wherein the former (Mannam) was born and brought up. On the day of performance of the last rituals followed by the untimely demise of the later (Kainikkara Govinda Pillai), in accomplishment of his unfulfilled desires and in his loving memory, the Nair community members of the locality assembled over there decided to form a Nairs organisation; and they named it as “Perunna East Nair Samajam”. Mannath Padmanabha Pillai was elected as its first secretary. It was in the year 1910 (1086). They later constructed a Mandiram for this Samajam and its foundation stone was laid by His Holiness Thirthapada Paramahamsar.
This organisation was second of its kind in Kerala, the first being Ayiroor Nayar Samajam in Pathanamthitta District (then Quilon) that was registered in the year 1909 (1085).

The other eminent Nair community reformers renowned of those days were C. Krishna Pillai, C.V.Raman Pillai, P.Thanu Pillai, K Paramu Pillai, Swami Theertha Pada ParamaHamsar, Kappana Kannan Menon, K. Kelappan Nair, Mahilamandiram K. Chinnamma and the social organizations formed in those days were:
1. Nair Purushartha Sadhini Sabha (Founded by Swami Thirthapadar)
2. Malayalee Social Union that was later renamed as Malayalee Sabha in 1886 during the reign of Maharaja Visakham Thirunal .
3. Daily Newspaper “Malayalee”, its chief editor C.V.Raman Pillai.

Those organizations had not lived long. In Jan 1905, formed Keraleeya Nayar Samajam. was then formed and it was registered under company act in 1912 and C. Krishna Pillai was its President and C.V. Raman Pillai, the Secretary. Today’s System of Nair Karayogams was the great idea and vision of TheerthaPada Swamikal (Poorvasrama Name: North Paroor, Madathil, Narayana Kurup). C. Krishna Pillai was its staunch supporter. Abolition of Namboothiri Sambandham, Thalikettu Kalyanam and varies of other regressive customs prevailed in that age; promotion of agriculture, commerce and industry activities among Nair community members were the intended mission of the Keraleeya Nair Samajam. Unfortunately, due to difference of opinion in the leadership, this organisation also could not accomplish its mission and was later divided into two groups. “Samastha Kerala Nayar Samajam” was thus formed anew under the Presidentship of C. Krishna Pillai, whose blessings were always with Mannathu Padmanabhan in his unmatched majestic endeavors in fulfillment of the community services ahead.

Both the Keraleeya Nayar Samajam and Samastha Kerala Nayar Samajam gradually demised when Nair Service Society started its endless expansions under the captainship of Mannath Padmanabhan.Nair Bh’rithyajana Sangham was later renamed as Nair Service Society under the scholastic advice of the great personality K. Paramu Pillai who was the first person to have had achieved M.A. degree in Kerala history (He was later known as M.A. Paramu Pillai).

In its plight, N.S.S. had conquered all areas of social, cultural, economical, educational, industrial segments and revived our community as a whole from the depth of chaos indeed from the bitterness our numerous destructive customs. Yet, we have to accelerate our spirit to go at par with other communities in this modern age. We have to determine ourselves that we are not lagged behind in any spheres. Our Samudayacharyan had suffered a lot to get our community to today’s stature. Let us and our descendents follow His divine foot steps leading to victorious hemispheres!
