Final answer:
The revival of cultural hairstyles like braids in the 20th and 21st centuries resulted in bans in various professions and schools, leading to lawsuits. This was part of a larger movement of cultural expression and identity, especially during the civil rights era.
Step-by-step explanation:
The revival of cultural hairstyles, such as braids, took place in the 20th century and continued into the 21st century. This resurgence led to controversies regarding dress codes and professional appearance standards. Consequently, the banning of braids in various professions and even high schools emerged, sparking numerous lawsuits. These actions were taken in the context of cultural expression and identity, especially among African Americans during movements like the Harlem Renaissance and the Black Pride Movement. The historical context of the resurgence can be traced back to urban migration and the transformation of Black identity and aesthetics, particularly during the civil rights era of the 1960s and 70s.
