Final answer:
Comedy of Manners satire in plays during the Restoration period and continued by playwrights like Oscar Wilde targeted the romantic entanglements and societal norms of the upper class, reflecting the times' shifting class structures.
Step-by-step explanation:
The main target of Comedy of Manners satire was the romantic entanglements of the upper class. This form of theatre, popular during the Restoration period, put aristocratic themes, social intrigue, and the sexual reputation of its characters at the forefront of its humor. Figures such as Oscar Wilde furthered the genre, with plays like The Importance of Being Earnest providing sharp criticism of societal norms through witty dialogue and situations reflecting the absurdities of upper-class customs and romantic conventions. By utilizing characters and their social status to poke fun at the aristocracy, especially in England, these plays successfully integrated a critical viewpoint with entertainment. Significantly, the transition of society from the noble class to the emerging middle class was mirrored in the evolution of theatre, leading to changes in staging and narratives that reflected these societal shifts.
