The association of Armenians with India and the presence of Armenians in India are very old, and there has been a mutual economic and cultural association of Armenians with India. Central Asians in ancient Indian literature and Hinduism in Armenia The earliest documented references to the mutual relationship of Armenians and Indians are found in Cyropaedia (Persian Expedition), an ancient Greek work by Xenophon (430 BC – 355 BC). These references indicate that several Armenians traveled to India. An archive directory (published 1956) in Delhi, India states that an Armenian merchant-cum-diplomat, named Thomas Cana, had reached the Malabar Coast in 780 using the overland route. The Ottoman and the Safavid conquests of the Armenian highlands in the 15th century CE meant that many Armenians dispersed across the Ottoman and Safavid empires, with some eventually reaching Mughal India (Northern India). During the reign of the Mughal emperor Akbar, Armenians—such as Akbar's wife Mariam Begum Saheba and a Chief Justice Abdul Hai—gained prestige in the empire. While Armenians gained prestige serving as governors and generals elsewhere in the empire such as Delhi, Lahore and the Bengal, living in enclosed colonies and establishing churches. Armenians worked as merchants, gunsmiths, gunners, priests and mercenaries for some of the Islamic rulers in India, with many noted to have served in the armies of various nawabs in Bengal and Punjab, such as Khojah Petrus Nicholas and Khojah Gorgin Khan. Thomas Cana was an affluent merchant dealing chiefly in spices and muslins. He was also instrumental in obtaining a decree, inscribed on a copperplate, from the rulers of Malabar (present-day Kerala and the Deep-South), which conferred several commercial, social and religious privileges for the Christians of that region. In current local references, Thomas Cana is known as "Knayi Thomman" or "Kanaj Tomma", meaning Thomas the merchant. Centuries later, an additional incentive for Armenian settlements in India was an Armenian agreement with the British East India Company.
