Stephen's views on state administration were summarized around 1015 in a mirror for princes known as Admonitions. Stating that "the country that has only one language and one custom is weak and fragile", he emphasized the advantages of the arrival of foreigners, or "guests". His laws were aimed at the adoption, even by force, of a Christian way of life. He especially protected Christian marriage against polygamy and other traditional customs. Decorated belts and other items of pagan fashion also disappeared. Commoners started to wear long woolen coats, but wealthy men persisted in wearing their silk kaftans decorated with furs.
