Ralph Shaa

Who was Ralph Shaa?

Ralph Shaa, was a 15th-century English theologian, the half-brother of the Lord Mayor of London, Edmund Shaa. Shaa played a minor but pivotal role in the Wars of the Roses by preaching a sermon in 1483 which claimed that Edward IV had already been betrothed to another woman at the time of his marriage to Elizabeth Woodville, and that Edward V was therefore illegitimate and had no claim to the throne.

Shaa appears as "Shaw" in Shakespeare's play Richard III.
