The Diocese of Calcutta, Church of North India was established in 1813 as part of the Church of England. It is led by the Bishop of Calcutta and the first bishop was Thomas Middleton (1814–1822) and the second Reginald Heber (1823–1826). Under the sixth bishop Daniel Wilson (1832–1858), the see was made Metropolitan (though not made an Archbishopric) when two more dioceses in India came into being (Madras, 1835, and Bombay, 1837).
