Hinduism spread to Nigeria mainly by immigration of Hindus from India and by way of Hare Krishna missionaries. Sindhis were the first to arrive in Nigeria in the early part of the nineteenth century. Initially, they were primarily engaged in trading. But gradually, while still retaining their interest in trading, they also ventured in to other fields like manufacturing and professional services. In succeeding decades, they made substantial investments in Nigeria, aggregating more than US$ 4 billion. In this way, they engaged themselves actively in the textiles sector, as well as in pharmaceuticals, fishing and various engineering industries.
