What is the political theme of Pride and Prejudice?My teacher said that political theme is how individuals and/or societies use power and establish...

Politics consist of "social relations involving authority
or power and refers to the regulation of a political unit, and to the methods and
tactics used to formulate and apply policy"
(Dictionary.com).

If this is the definition your teacher is
using, Darcy, and his aunt Lady Catherine are at the heart of the upper class. They are
powerful in the decisions they make and have authority because of their social standing.
The Bingleys have social status because they accumulated great wealth in merchant
trade.

One had to be of high social standing to circulate
in their group of friends. In fact, social standing is one reason Mr. Bingley agrees not
to marry Jane initially. In fact, his sister makes the comment about the possible
relationship as saying, "You can't be serious."

Initially,
Darcy is turned off to the thought of being interested in Elizabeth because of her
family's imprudent behavior. He claims that she is inferior to him by virtue of the
crassness of her mother and sisters. But Elizabeth tells Lady de
Bourgh:

He is
a gentleman; I am a gentleman's daughter; so far we are equal [in social rank] (Chapter
56).

Ultimately, love
prevails and Darcy decides to ask Elizabeth to marry him despite her family. Initially,
Elizabeth refuses due to her own prejudices against the snobbery of men like
Darcy.

Darcy is a political entity in that he has authority
because of his social status. The way the political system works is that people with
money have all the power: Money determined power. Politics is totally dependent upon the
people with the wealth. Politicians usually are of upper class birth and rank. Darcy,
though not of the nobility
(Mr. Darcy) was such a man based on
his family connections and upper-class rank.
