This riding was created in 1907 following the admission of Saskatchewan into the Canadian Confederation in 1905.
The riding was located in the southeast corner of Saskatchewan until the 1949 election, when it was moved westward to be based around the community of Assiniboia.
Its new territory was carved out of parts of Wood Mountain and Weyburn.
It was abolished in 1987 when it was redistributed into Moose Jaw—Lake Centre, Regina—Qu'Appelle, Regina—Wascana, Souris—Moose Mountain and Swift Current—Maple Creek—Assiniboia ridings.
