What is the meaning of [A man’s house is his castle]

He is legally entitled to his privacy. No other person may enter his house
without his permission.

United States Senate on May 10th, 1880:

> ‘I think some orator said that though the winds of heaven might whistle
around an Englishman’s cottage, the King of England could not.’
