Museums, galleries and heritage sites will play a key part in the cultural events that will mark the anniversary of final year of world war one, it was announced this week by 14-18 Now, the organisation set up to deliver the programme.

Special themes of the 2018 season include the centenary of the Representation of the People Act, which gave women the right to vote; an exploration of the impact of war beyond the UK, including the role played by soldiers from Africa, India and the Caribbean; and the centenary of the 11 November Armistice.

One high-profile project is a film being made with archive footage from the Imperial War Museums' (IWM) film archive and audio from the BBC archives. It will be developed by Lord of the Rings director Peter Jackson and will be accompanied by a UK-wide learning programme for secondary schools.
