Final answer:
The late 19th-century song 'John Henry' was likely influenced by the Industrial Revolution and the Civil War. These events marked significant economic and societal shifts in America and reflected the struggle between man and machine, as well as the experiences of African Americans post-Emancipation.
Step-by-step explanation:
The song John Henry was written in the late 19th century. Two historical events during this time that may have influenced it are A. The Industrial Revolution and the Civil War. The Industrial Revolution marked a shift from an agricultural economy to one that was industry-based, leading to the rise of factories and mass production. This created a new economic dynamic and class distinction as the wealth became more unequally distributed, highlighting the struggle between man and machine that is central to the story of John Henry. Moreover, the Civil War was a period of profound national conflict and transformation that influenced all aspects of American life, including its folklore and songs. The Emancipation Proclamation, a result of the Civil War, also played a significant role in shaping the nation and could have been a secondary influence on the song, as it reflected the struggles and the strength of African Americans during and after the war.
