The term "Prince Regent" refers to a person appointed to act on behalf of a monarch who is unable to fulfill their duties due to illness, absence, or other reasons. This role often involves overseeing the day-to-day affairs of the state and making decisions in the monarch's stead. The position can be temporary or last for an extended period, depending on the circumstances. One of the most notable examples of a Prince Regent is George IV of the United Kingdom, who served as regent from 1811 to 1820 while his father, King George III, was incapacitated. During this time, the regency was marked by significant political and social changes, including the rise of the Romantic movement in art and literature.
