This Day In Arizona History charts some of the memorable moments in our state's history spanning Arizona's Territorial Days to the late 20th century. This Memory Project collection shows the breadth of history from the political to the personal, noting the births and deaths of the famous and the infamous, the building of key Arizona landmarks, and the twists and turns of government, the economy, science and technology and society. The impact of Arizona's growth, the Great Depression, two World Wars and social revolutions in the mid-20th century can be seen throughout the collection. Also included are smaller (but just as telling) moments in history such as local dairy price wars, the trial use of camels in the desert, and Girl Scout cookie sales. The images corresponding to each day's event come from the more than 750,000 images in the Arizona Historical Society's photographic collections.
