Answer:
The political idea was that the king, while powerful and the undisputed leader of the nation, had certain limitations to his power, and had to respond to a certain extent to the English Parliament. This idea was formed by the Carta Magna, signed in the Middle Ages.
The social idea was that the social structure, while still rigid, had more mobility than in many other European states at the time. This is because trade and crafts were promoted and developed in England, which helped people that did not have a noble background, to accumulate wealth and move up the social ladder.
The religious idea was that England was a Protestant Nation, ruled by the Church of England, or the Anglican Church. England was therefore part of Protestant Europe, along with Scotland, the Nordic Countries, and some parts of Central Europe, in contrast to Catholic Europe, which dominated the rest of Western and Southern Europe.
