5th Arizona State Legislature

The 5th Arizona State Legislature, consisting of the Arizona State Senate and the Arizona House of Representatives, was constituted from January 1, 1921, to December 31, 1922, during the third term of Thomas Edward Campbell, as Governor of Arizona, in Phoenix. While the Senate remained at 19 members, the size of the House was increased from 35 to 39, with 3 additional representatives added to Maricopa County, and an additional representative for Pinal County. For the first time, the Republicans achieved a majority in one of the houses, the Senate, with a 10–9 edge, while the Democrats were able to barely hold on to their majority in the House, 20–19.
