American Baptists started missionary work in South India among Telugu-speaking people in 1836. In February 1840, Samuel Day along with his family moved to Nellore and rented a small bungalow to start his work. In March 1840, one more missionary couple, Van Husen and his wife joined them and with the help of a local British judge, Mr. Walker, they got some eight acres of land for a mission compound where a bungalow and a chapel were immediately erected on this land by 1841. On September 27, 1840, the first Telugu person Venkappa was baptised in the Penna river near Nellore. The Nellore church was formally organized in 1844 with 8 members including two missionary couples, two other Americans, and only two local people. The first local person to be ordained as a priest by the mission was Kanakiah who was from the Naidu caste and a native of Visakhapatnam. In 1855 when he was eighteen years old he took baptism and in 1860 he became the first ordained native pastor of the Nellore church. In 1887 the existing churches were organized into the Convention of Telugu Baptist Churches. In 1962 the convention became the Samavesam of Telugu Baptist Churches, with a unanimously adopted constitution. It was registered in 1963.
