The website of the Commonwealth War Graves Commission (CWGC) has been developed to provide an online database for soldiers from all countries belonging either to the former British Empire or to the British Commonwealth who were killed during action in 153 countries around the world, and to search for particular cemeteries. You can find information about 1,700,000 people and some 23,000 cemeteries. The website has a section with articles about some of the battlegrounds of the First World War. The CWGC was founded in 1917. There is a page with information about similar organisations in several countries and their websites.
