I'm trying to identify the main themes in French history from 1945 to present. I'd say social development and social hardship are two important themes: As per the rebuilding of the welfare infrastructure post-war and the social hardships/unrest which are characterised by riots in France (1968, 1990s, 2005) - as they are generally founded on unemployment, pay disputes and concepts of a "tale of two cities" within Paris and its suburbs.

Furthermore I'd say economic changes in France are important and relevant to these points, as with the Gaullist sentiment in politics during the 1968 of economy being more important than social issues - Even perhaps to say it was a modernised society living largely with social elements of the 1800s under the rule of Charles de Gaul's traditional sentiments as president.

I'd love for anyone more knowledgeable to chime in here, nothing too in depth but I'm struggling to see many/any others significant recurring themes. Thanks!
