What was the significance of Canberra's foundation?

The significance of Canberra's foundation lies in the deliberate creation of a purpose-built national capital that resolved the Sydney-Melbourne rivalry, established a distinct symbolic centre for the new Australian nation, and produced one of the world's few successful planned capital cities. The federal capital site at Yass-Canberra was selected in 1908 and the Commonwealth officially took possession of the Australian Capital Territory in 1911.

The foundation followed a long constitutional and political process. Section 125 of the Australian Constitution, negotiated during the second round of federation referendums in 1899, required that the capital be in New South Wales but at least 100 miles (160 kilometres) from Sydney. Multiple sites in NSW were considered between 1903 and 1908. The Seat of Government Act 1908 selected Yass-Canberra. The Seat of Government Acceptance Act 1909 formally transferred the territory from NSW to the Commonwealth. King George V proclaimed the Australian Capital Territory on 1 January 1911.

The name Canberra was settled at a public ceremony on 12 March 1913, when Lady Denman (wife of the Governor-General) officially named the city. The name is thought to derive from the Ngunnawal Aboriginal word meaning 'meeting place', a designation that the federal capital was intended to fulfil. The Griffin master plan was selected through an international design competition in 1911 to 1912 from 137 entries, with American architects Walter Burley Griffin and Marion Mahony Griffin's submission winning. Construction began in 1913, although it was slowed by the First World War, the Depression, and ongoing political controversies.

Several key milestones marked the foundation. Parliament moved from Melbourne to Canberra in 1927, with the Provisional Parliament House (now Old Parliament House) opened by the Duke of York on 9 May 1927. The Australian War Memorial opened on 11 November 1941 (Remembrance Day). Lake Burley Griffin was filled in 1964. The National Gallery of Australia opened in 1982. The current Parliament House on Capital Hill, designed by Romaldo Giurgola, was opened by Queen Elizabeth II on 9 May 1988. The High Court of Australia's purpose-built building opened in 1980. The National Museum of Australia opened in 2001 (the centenary of federation). Together these institutions make Canberra not just the seat of federal government but the country's principal cultural and constitutional centre. The ACT became self-governing in 1989, with its own Legislative Assembly performing both state and local government functions.
