Answer:
In the mid-1800s, American literature and arts began to change as authors and artists began to depict American life rather than classical European subjects.
Step-by-step explanation:
Fine arts in the United States developed under conditions very different from those that occurred in many other nations. The United States was formed from a group of colonies; its founders came from different places with different customs and traditions. These, suitable for the needs of society in their countries of origin, had to adapt to life in a strange and adverse environment. A properly American culture, founded on these traditions modified from distant regions, although different from them, grew and developed only after the United States became an independent nation. This situation occurred in the mid-1800s, when almost 100 years after independence, the United States had a national identity forged and established in its population.
