The title of city was initially informal and, into the 20th century, royal charters were 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.
