Nobles were always recognized as lower families of the King/Queen. Nobles usually rule Duchies, Counties, and principalities. Nobles were usually given a "House", being of course a noble house. Nobles usually worked as advisors to the King, and land owners. Some families did not work at all because they were quite wealthy. But not all nobles were wealthy. Some were very poor. One of the richest claim to be noble families were the Medicis. The Medici's ruled Tuscany, Milan ect. The Medici's were pretty much common people, but they were richer than most monarchs at there time until there fall in the 1700's.
