What is one characteristic of the post-World War 1 era?

One characteristic of the post-World War I era was a significant shift in social norms and cultural attitudes, particularly regarding gender roles and individual freedoms.

Additionally, there was a sense of disillusionment and a search for new forms of expression in art and literature, exemplified by movements like Modernism and the Lost Generation.
