The 1773 conquest of the
Mysore King Hyder Ali in the Malabar region descended to Kochi. The Kochi Raja had to pay a subsidy of one lakh of Ikkeri Pagodas (equaling 400,000 modern rupees). Later on, in 1776,
Hyder Ali captured Thrissur, which was under the Kingdom of Kochi. Thus, the Raja was forced to become a tributary of Mysore and to pay a nuzzar of 100,000 of Pagodas and 4 elephants and annual tribute of 30,000 Pagodas. His son Tipu Sultan`s invasion had an adverse impact on the Syrian Malabar Nasrani community of the Malabar coast. Many churches in Malabar and Cochin were damaged. Tipu`s army set fire to the church at Palayoor and attacked the Ollur Church in 1790. Furthermore, the Arthat church and the Ambazhakkad seminary was also destroyed. Over the course of this invasion, many Syrian Malabar Nasrani were killed or forcibly converted to Islam. Most of the coconut, areca nut, pepper and cashew plantations held by the Syrian Malabar farmers were also indiscriminately destroyed by the invading army. The Syrian Christian community fled Calicut and small towns like Arthat to new centers like Kunnamkulam, Chalakudi, Ennakadu, Cheppadu, Kannankode, Mavelikkara, etc. where there were already Christians. They were given refuge by Sakthan Tamburan, the ruler of Cochin and Karthika Thirunal, the ruler of Travancore, who gave them lands, plantations and encouraged their business. Colonel Macqulay, the British resident of Travancore also helped them.
