Sometime between the 4th and the 9th century, Thomas of Cana, led a migration of Syriac Christians from the Middle East to India. This historical migration strengthened the ties between the Indian church and the Church of the East.
Thomas of Cana led a group of 72 families, as well as clergymen, to the Malabar (modern Kerala) coast. There they met and supplemented the Syrian Christians (also know as Saint Thomas Christians), who had been evangelised by Thomas the Apostle in the 1st century.
Thomas is said to have been a Syrian merchant, distinct from Thomas the Apostle, who preceded him in evangelising in India.
