Poykayil Sree Kumara Gurudevan (17 February 1879, in Eraviperoor – 1939), known as Poykayil Appachan or Poykayil Yohannan, was a spiritual leader, poet, Dalit emancipator, renaissance leader and the founder of the socio-religious movement Prathyaksha Raksha Daiva Sabha ("God's Society of Obvious Salvation").^{[1][full citation needed]}

Yohannan joined the Marthoma church, a reformist sect among the Syrian Christians, but realised the church treated Dalits as an inferior class, and so left it. He then joined a new sect called the Brethren Mission where he faced similar instances of caste based discrimination. Johannan concluded that Indian Christian communities continued to discriminate based on caste, and felt this defied the basic tenets of Christianity.^[2]

In 1909, Yohannan left Christianity and started his own religious protest movement named Prathyaksha Raksha Daiva Sabha. He was known as Poikayil Appachan or Kumara Gurudevan afterwards.^{[citation needed]} Johannan advocated spiritual liberation, and sought to empower and consolidate the Dalits, promoting a creed in which the "dalit castes" would be free of discrimination.^{[3][better source needed]}

Appachan was nominated twice, in 1921 and 1931, to the Sree Moolam Praja Sabha, the legislative council of the princely state of Travancore.^[4]
