Legislative bodies or advisory bodies to a monarch were traditionally grouped along lines of these estates, with the monarch above all three estates. Meetings of the estates of the realm became early legislative and judicial parliaments. Monarchs often sought to legitimize their power by requiring oaths of fealty from the estates. Today, in most countries, the estates have lost all their legal privileges, and are mainly of historical interest. The nobility may be an exception, for instance due to legislation against false titles of nobility; similarly British government well maintains the distinction – witness its House of Lords, and the House of Commons.
