British History Online

British History Online is a collection of nearly 1300 volumes of primary and secondary content relating to British and Irish history, and histories of empire and the British world. BHO also provides access to 40,000 images and 10,000 tiles of historic maps of the British Isles.

On February 29 2024, we upgraded our website to Drupal 10, and moved server. In the process, there have been a number of problems with subscriptions, logging in, and searching the content. We are working to fix these problems, and appreciate your patience whilst this is accomplished.

Additionally, we are making the old site temporarily available at, so that the old search functionality may be used.
