The Kerala Brethren are a significant subset of the Open Brethren movement. In the South Indian State of Kerala, four Syrian Christian (Nasrani) men who came from traditional churches were baptised in 1898, and many of the Kerala Brethren consider this event to have been the start of their movement. Some 600 of the 2,200 Brethren assemblies (as their churches are generally called) in India are located in Kerala.
