    Capitol history - Still a territory, Colorado had already had two other capital cities when the Seventh Legislative Assembly on December 9, 1867, made Denver the official capital city. Although Golden had been the official capital for several years, most of the government business was transacted in Denver and popular convenience led to officially moving the capital there. In Denver the territorial offices were scattered about town and the legislature met where it could.
             The election on November 8, 1881, made Denver the capital by some 17,000 vote majority. Denver received 30,248 votes, Pueblo had 6,047, Colorado Springs 4,790, Canon City 2,788 and Salida 698. Another 929 votes were scattered among other cities.
