Iowa’s first constitution of 1846 required blacks to pay a $500 bond to enter the state and barred them from voting, holding office, serving in the state militia, attending public schools and marrying whites. In this clip from the Lost in History: Alexander Clark documentary, historian David Broadnax explains how Alexander Clark participated in a campaign for voting rights in Iowa after the end of the Civil War. The campaign was successful and in 1868, Iowa became the first state outside of New England to grant African-American men the right to vote.
