The first one is historical and chronological. It explains the four steps of French Baptist implantation, from 1800s to 1950s.
The second one is a thematic presentation, using both sociology and history, in order to highlight the social distinctives of Baptist churches (and individuals) in French society.
These two slideshows are in French. They may require some effort to be read and understood but the effort is worth it!
