Muhammad Ali, world boxing champion and civil-rights activist, died in June 2016.
This is a nice summary of Ali’s life and career from the BBC children’s news site. The video covers much the same information as the article, and could be tackled from A2, or used just for images along with selected facts for lower levels.
This tribute from the Muhammad Ali Center, the boxer's museum and foundation in his hometown of Louisville, is perfect for lycée students, especially the six guiding principles.
And this article from the BBC will also appeal to older students: it's about a special edition comic from 1978 which had Superman opposed to Muhammad Ali.
