Which wife were beheaded for adultery?

Two of King Henry VIII's wives were executed for adultery: Anne Boleyn and Catherine Howard. Anne Boleyn, the second wife, was beheaded in 1536 after being charged with treason, adultery, and incest, though many historians believe the charges were fabricated. Catherine Howard, the fifth wife, was executed in 1542 on similar charges of infidelity. Both women faced a tragic end amid the political and personal turmoil of Henry's reign.
