5. First Female Governor: On June 19th, 1985, Terry Branstad, the governor of Iowa at the time, signed a proclamation designating July 7th, 1985, as "Women's Equality Day" in Iowa.

Clarke became governor when Branstad resigned to become the ambassador to China, and Lieutenant Governor Robert D. Ray was out of the state, making her the first female governor in Iowa's history.
