T.J. Ryan resigned as premier a year after the state election to run successfully for the federal seat of West Sydney in 1919. Ryan was replaced as premier by Ted Theodore. Theodore called the 1920 election one year into his premiership and two years after the 1918 election. After the election, Macartney returned to the leadership of the Nationalists, replacing Tolmie. He was later replaced for a second time, this time by William Vowles. Within a few months though, Vowles created the Queensland Country Party. However, because Vowles had created the Country Party using most of the rural-based Nationalist MLAs, Vowles was able to remain as Opposition Leader.
