Bell entered politics in 1886 when he was elected to the province's legislative assembly as a Liberal. In 1898 he won a seat in the House of Commons of Canada as a supporter of the federal Liberals under Sir Wilfrid Laurier. He lost his seat in 1900 but returned to the provincial assembly in 1915 when he was chosen to lead the Liberal Party and became leader of the opposition. After Bell led the Liberals to power in 1919, he became Premier. His government extended the province's road system and adopted a highway improvement policy funded by a tax that contributed to the government's unpopularity. His administration also extended the voting franchise to women in 1922.[citation needed]
Bell's government was ridden with disputes within his cabinet, which harmed the party's unity and popularity and led to his government's electoral defeat in 1923 after a single term in office. Bell retired from politics and died six years later in a car accident in Los Angeles, California.[citation needed]
