The setting of New England in 1866 is significant to the structure of the play for several reasons. Firstly, the historical context of post-Civil War America may influence the themes and character dynamics present in the narrative, such as the implications of social change, the struggle for identity, and the impact of war on society and individuals.
Additionally, the geographical location can shape the characters' lifestyles, values, and interactions, as New England was known for its distinct cultural and social norms at that time. The setting may also reflect issues related to regionalism and highlight differences between urban and rural life, the classes, and cultural identities.
Furthermore, this time period can affect the play's pacing and conflicts, as societal expectations and gender roles were markedly different in the 19th century, potentially impacting character motivations and plot developments.
In summary, the setting of New England in 1866 serves as a backdrop that informs the play's themes, character development, and overall structure, making it a crucial element in understanding the narrative.
