Here's a clearer breakdown:
* Hughes moved to Harlem in 1921: He was drawn to the vibrant cultural scene and the burgeoning Harlem Renaissance.
* Shuffle Along premiered in 1921: The show was a hit and made Hughes's lyrics and contributions famous, boosting his literary career.
The success of Shuffle Along did, however, solidify Hughes's position in the Harlem Renaissance and allowed him to make a living as a writer, contributing to his staying in Harlem.
So, while Shuffle Along wasn't the reason Hughes moved to Harlem, it definitely fueled his literary career and allowed him to flourish within the Harlem community.
