The following chronology covers the main elements of the history of Glamorgan mainly for the period up to 1960 with a few later events. It is intended to be of use to people researching their family history in the area, in order to provide a background to their research and maybe some pointers as to why their ancestors lived where they did or moved in or out of the area. It includes the dates of foundation of many of the main organisations in the county, the opening of older churches (but not the original parish churches) & chapels (mainly before 1850), Theatres, Cinemas, Old Inns & Hotels & Industrial Companies. I realise that it is not exhaustive and undoubtedly people who know the county will find that things that they might have included are not in my list. If anyone wants anything added I shall be pleased to consider it if they can give me the details. It is my hope that I will, in any case, be able to make additions in time.

The chronology can be read in conjunction with my Cardiff & Vale Chronology, and some events will be found in both.

A Wales timeline is already available via the Glamorgan Help pages and I have produced a Chronology of British History which is available on my website.

In order to find a specific event without reading through the whole list please use the "find" facility of your browser. In this way you should be able to find any references to a particular year or subject.
