Input: Mali
In the far north, there is a division between Berber-descendent Tuareg nomad populations and the darker-skinned Bella or Tamasheq people, due the historical spread of slavery in the region. An estimated 800,000 people in Mali are descended from slaves. Slavery in Mali has persisted for centuries. The Arabic population kept slaves well into the 20th century, until slavery was suppressed by French authorities around the mid-20th century. There still persist certain hereditary servitude relationships, and according to some estimates, even today approximately 200,000 Malians are still enslaved.

Input: The Blitz
Public demand caused the government in October 1940 to build new deep shelters:189190 within the Underground to hold 80,000 people but were not completed until the period of heaviest bombing had passed. By the end of 1940 significant improvements had been made in the Underground and in many other large shelters. Authorities provided stoves and bathrooms and canteen trains provided food. Tickets were issued for bunks in large shelters to reduce the amount of time spent queuing. Committees quickly formed within shelters as informal governments, and organisations such as the British Red Cross and the Salvation Army worked to improve conditions. Entertainment included concerts, films, plays and books from local libraries.
