Wuhan diocese, formerly known as Hankou archdiocese, was erected first as the Apostolic Vicariate of Eastern Hupeh (Hubei) in 1870 and was later renamed to Hankou in 1923. Its boundaries shrunk after losing territories to newly-erected apostolic vicariates in the province, over the years. In 1946, it was elevated to an archdiocese when the Chinese Church hierarchy was established.
In 1958, the first-ever illicit episcopal ordinations (without papal approval) in the history of the Chinese Church took place at St. Joseph's Cathedral of Hankou. Father Bernardine Dong Guangqing and Father Yuan Wenhua were ordained as the first two "self-elected and self-ordained" bishops of Hankou and the neighboring Wuchang diocese. The Vatican denounced such illegal acts, but decades later it gave recognition to Bishop Dong in 1984. Bishop Yuan died in the year 1973, during the Cultural Revolution.
In 2000, the government-sanctioned "open" Church authority merged Hankou, Hanyang, and Wuchang dioceses into Wuhan.
