What era is known for the rise of the foxtrot as a popular dance?

The 1920s are known for the rise of the foxtrot as a popular dance, largely due to the cultural shifts and social changes taking place during this time. This decade, often referred to as the Roaring Twenties, saw the emergence of jazz music and dance halls, where the foxtrot became a staple on the dance floor. The dance evolved from earlier forms, incorporating smooth, flowing movements that appealed to the public.

The foxtrot's popularity was also supported by the influence of big bands and jazz orchestras, which provided an upbeat tempo that was perfect for dancing. Additionally, the social atmosphere of the 1920s encouraged public gatherings and recreational activities, making dance a prominent form of entertainment. This era also featured the establishment of dance marathons and competitions, further solidifying the foxtrot's status as a favored dance style among young people.

While the foxtrot had earlier origins, it was during the 1920s that it truly flourished and became synonymous with the vibrant nightlife and cultural dynamism of the time. The other options do not correlate with the peak popularity of the foxtrot, as it did not gain significant traction until the 1920s.
