Literary history is the study of literature over time, examining how different works reflect the culture, society, and values of their periods. It involves analyzing various genres, movements, and authors, such as Shakespeare or Romanticism, to understand their impact on literature and society. This field also explores the evolution of language and themes, showing how literature responds to historical events and changes in thought. By tracing the development of literary forms, scholars can identify trends and influences, helping to contextualize works within the broader narrative of human history and artistic expression.
