In Jane Austen's Pride and Prejudice, how closely do the characters reflect the historical accuracy of culture within the community?

Among the genteel society of Jane Austen's class, as
depicted in Pride and Prejudice, it was certainly the norm to frequently entertain
through balls, dinners, and frequent social calls, as we see all of the characters
doing. The ways in which the community of Hertfordshire socially engages, is certainly
accurately depicted.

Another aspect of culture found, not only in
Hertfordshire, but in England at large for the time period, was the mingling of social
classes and the questions it raised. During this time period, England was at war with
France at the time of the French Revolution. England, wanting to avoid their own
revolution began to soften the hard lines of demarcation separating social classes. The
aristocracy, not wanting to loose their heads as the French aristocracy did, began to be
less assertive with respect to their superiority, as we see Darcy do. Not only that,
England's middle class, such Elizabeth's relations like the Gardiners, began
intermingling and intermarrying with the aristocracy, as we also see depicted in
Pride and Prejudice.

Hence, the characters in
Pride and Prejudice give a very accurate portrayal of the society
and culture of Austen's time.
