Final answer:
Women were nicknamed flappers during the 1920-1930 era, as they embraced new lifestyles and fashions, challenging traditional norms and embodying the spirit of the Jazz Age and women's rights movements.
Step-by-step explanation:
Some women were nicknamed flappers during the 1920-1930 period, known as the Jazz Age. This era was a time of significant social change and cultural upheaval, particularly for women. The flapper lifestyle emerged part-and-parcel with the larger women's rights movement, as the ratification of the Nineteenth Amendment in 1920 granted full voting rights to women. Flappers challenged traditional Victorian norms by adopting new fashion styles, such as knee-length skirts and short haircuts, and engaging in behaviors like smoking and drinking, which were previously considered unfeminine. Their choices in dress, dance, and social interaction were expressions of their independence and an expansion of the concept of women's liberation.
