Western Australia gained the right of self-government in 1890, and joined with the five other states to form the Commonwealth of Australia in 1901. The desire of Western Australians to revert to complete self-governance, separate from the Commonwealth, culminated in 1933 with a successful referendum for secession supported by 68% of electors. In 1935 the British parliament declined to act since secession would require the assent of the Australian parliament, and the movement lapsed with an improving economy and generous federal grants.
