The Idaho Press-Tribune is the second-oldest active newspaper in Idaho, first printing in December 1883. Often, the early paper was an instrument for political influences. One of the first owners and editors was Frank Steunenberg. After his murder, the Steunenbergs sold it to Rees H. Davis, editor of the Idaho Woman. The publication is oft credited with playing a key role in the passage of women's right to vote. On April 12, 1928, the Caldwell Tribune and Caldwell News merged and became the Caldwell News-Tribune.
