Don't tell me not to go around the house in my underwear. A man's home is his castle. I'll play my radio loud if I want to. A man's home is his castle.
Traditional; the sentiment dates back to Roman times:
- quid enim sanctius, quid omni religione munitius, quam domus unusquisque civium?
- What more sacred, what more strongly guarded by every holy feeling, than a man's own home? - Cicero
The first known use of this expression is in The Stage of Popish Toyes (1581), a short book written by Frenchman Henri Estienne (1531-1598), an examination of anti-Catholic propoganda, derived in large part from Estienne's Apologie pour Hérodote.
In 1644, English judge Sir Edward Coke was quoted as saying, "For a man's house is his castle".
The first known use in what would become the USA is in Will and Doom, or the miseries of Connecticut by and under usurped and abitrary power; being a narrative of the first erection and exercise, but especially of the late changes and administration of government in their Majesties Colony of New England in America, published in 1692 by Rev Gershom Bulkeley, son of Rev Peter Bulkeley who founded the town of Concord, Massachusetts.
It also is fundamental to the American system of government. In this regard, the Fourth Amendment to the United States Constitution — part of the Bill of Rights — prohibits “unreasonable searches and seizures.”
In England the expression is almost always "An Englishman's home is his castle".
