tying Minnu, a Hindu symbol of marriage is the most important rite in the Christian marriages too. In 1519, a Portuguese traveler Duarte Barbosa on his visit to Malabar commented on the practice of Saint Thomas Christian priests using Kudumi similar to that of Hindus, in his manuscript "Book of Duarte Barbosa". In the social stratification of medieval Malabar, Saint Thomas Christians succeeded in relating their social status with that of upper-caste Hindus on account of their numerical strength and influence and observance of many Brahmin and upper caste customs. In the 13th and 14th centuries, many Saint Thomas Christians were involved in the pepper trade for the local rulers and many were appointed as port revenue officers. The local rulers rewarded them with grants of land and many other privileges. With growing numerical strength, a large number of Saint Thomas Christians settled in the inland pepper-growing regions. They had the right to recruit and train soldiers and Christian trainers were given with the honorary title "Panikkar" like their Nair counterparts. They were also entitled with the privilege to collect the tax, and the tax-collectors were honored with the title "Tharakan". Like Brahmins they had the right to sit before the Kings and also to ride on horse or elephant, like the royals. They were protectors of seventeen underprivileged castes and communities and hence they were called Lords of Seventeen Castes. They did not allow the lower-castes to join their community for fear that it could imperil their upper-caste status. But this regal period ended when the community fell under the power of the Rajas of Cochin and Travancore. They owned a large number of Kalaripayattu training centers and the Rajas of Travancore and Cochin, including the renowned Marthanda Varma, recruited trained Christian warriors to defend their kingdom. The upper-caste Hindus and Saint Thomas Christians took part in one another's festival celebrations and in some places in Kerala, the Hindu Temples and Saint Thomas Christian Churches were built on adjoining sites by the Hindu Kings. Until the 19th century, Saint Thomas Christians had the right of access to Hindu temples and some leading Saint Thomas Christians held the status of sponsors at Hindu shrines and temple festivals. But in the 19th century, Saint Thomas Christian integration with the Hindu caste system was disrupted: their clean-caste status was questioned in some localities and they were denied access to many Hindu temples.
