considered to recognise city status rather than to grant it. The usual criterion in early modern Britain was the presence of a cathedral, particularly after King Henry VIII granted letters patent establishing six new cities when he established a series of new dioceses in the 1540s as part of the English Reformation. No new cities were created between the 16th and 19th centuries, but following the Industrial Revolution and the accompanying population boom and growth in urbanisation, new sees were established at Ripon (1836) and Manchester (1847); their councils began to style them cities immediately. Inverness in Scotland was even refused a charter at the time of the Jubilee honours of 1897, in part because it would have drawn more attention to the other traditional "cities" still not formally chartered as such. Beginning in the mid-19th century, however, the process became more formal. A visit by Queen Victoria in 1851 prompted Manchester to petition Parliament for recognition of its status. Ripon followed in the 1860s, and a series of hitherto informal "cities" were formally recognised in the 1880s and 1890s. On the basis of its size, importance, and regular government, Belfast was elevated in spite of its lack of a cathedral in 1888; other large municipalities followed, while smaller applicants began to be rejected. King Edward VII and the Home Office established three criteria for future applicants in 1907—a minimum population of 300,000, a good record of local government, and a "local metropolitan character" but these criteria were not made public, and following Leicester's successful elevation in 1919 a series of exceptions were made. The 1972 Local Government Act effectively eliminated all authorities holding city status outside Greater London on 1 April 1974; most of their replacements were confirmed in their predecessor's status—even in cases such as the City of Carlisle, where much of the local authority area is undeveloped countryside—but the Borough of Medway was not permitted to continue Rochester's title. In recent times there have been competitions for new grants of city status. Towns or councils that claim city status or add "city" to their name have been known to be rebuked by the Advertising Standards Authority. The cities of Scotland and Ireland were treated separately. Scottish towns irregularly applied the description to themselves, but were formally organised as royal burghs; the special rights of these were preserved by Article XXI of the Treaty of Union which established
