Retha Marvine Warnicke (born 1939) is an American historian and Professor of History at Arizona State University.
In addition to her efforts in the history department, Warnicke has also devoted much of her time to affirmative action and faculty rights.
Warnicke is the author of seven monographs, including The Marrying of Anne of Cleves: Royal Protocol in Tudor England (Cambridge University Press, 2002), Mary, Queen of Scots (Routledge, 2006), and Wicked Women of Tudor England: Queens, Aristocrats, and Commoners (Palgrave Macmillan, 2012).
These theories were outlined in various articles in the mid-1980s, "Anne Boleyn's Childhood and Adolescence" and "Sexual Heresy at the Court of Henry VIII".
The theories were built on and elaborated in her 1989 book The Rise and Fall of Anne Boleyn: Family politics at the court of Henry VIII.
