The House of Nádasdy, also spelled Nadasdy in English, is a major Hungarian aristocratic family whose roots reach into the Middle Ages.
[1] The house motto is, "Si Deus pro nobis quis contra nos," ("If God is for us, who can be against us?").
The Nadasdy family made a large contribution to the development of Hungarian printing.
The Nadasdy Hussars, a regiment named after the family, developed a strategy incorporating lightly armed and fast-moving cavalry that was internationally adopted.
[2] The name is first encountered in the early part of the 13th century, that of Imre (descendant of Darabos de Nádasd) and his sons, Stefánd, Tódor, and Valkomer.
