For many centuries, wealthy and powerful members of the szlachta sought to gain legal privileges over their peers. Few szlachta were wealthy enough to be known as magnates (karmazyni—the "Crimsons", from the crimson colour of their boots). A proper magnate should be able to trace noble ancestors back for many generations and own at least 20 villages or estates. He should also hold a major office in the Commonwealth.
