Over several centuries, Kerala has been influenced by several other cultures with which it shared trade relations. In AD 52, Christianity was introduced to India as St. Thomas, one of the twelve apostles of Jesus arrived and settled in Kerala. Later in the 7th Century, Islam arrived along with the Arab traders. All these religious beliefs got assimilated with the local beliefs and thoughts and formed a multicultural, diverse and dynamic society. Kerala has the highest literacy rate in India.
