The History of Parliament is a project to write a complete history of the United Kingdom Parliament and its predecessors, the Parliament of Great Britain and the Parliament of England. The history will principally consist of a prosopography, in which the history of an institution is told through the individual biographies of its members. After various amateur efforts the project was formally launched in 1940 and since 1951 has been funded by the Treasury. As of 2019, the volumes covering the House of Commons for the periods 1386–1421, 1509–1629, and 1660–1832 have been completed and published ; and the first five volumes covering the House of Lords from 1660 to 1715 have been published, with further work on the Commons and the Lords ongoing. In 2011 the completed sections were republished on the internet.
