Wuhan diocese was formerly called Hankou archdiocese. It was firstly erected as Apostolic Vicariate of Eastern Hupeh (Hubei) in 1870 and renamed to Hankou in 1923. Its boundaries became smaller and smaller 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 history of the Church in China took place at St. Joseph's Cathedral of Hankou. Fathers Bernardine Dong Guangqing and Yuan Wenhua were ordained the first two "self-elected and self-ordained" bishops of Hankou and the neighboring Wuchang diocese. The Vatican denounced such illegal act, but decades later it gave recognition to Bishop Dong in 1984. Bishop Yuan died in 1973 during the Cultural Revolution.
In 2000, the government-sanctioned "open" Church authority merged Hankou, Hanyang and Wuchang dioceses into one and renamed Wuhan, in accordance with the name of the city.
