Perth was founded by Captain James Stirling in 1829 as the administrative centre of the Swan River Colony. It gained city status (currently vested in the smaller City of Perth) in 1856 and was promoted to the status of a Lord Mayorality in 1929. The city inherited its name due to the influence of Sir George Murray, then Member of Parliament for Perthshire and Secretary of State for War and the Colonies. The city’s population increased substantially as a result of the Western Australian gold rushes in the late 19th century. During Australia’s involvement in World War II, Fremantle served as a base for submarines operating in the Pacific Theatre, and a US Navy Catalina flying boat fleet was based at Matilda Bay. An influx of immigrants after the war, predominantly from Britain, Greece, Italy, and Yugoslavia, led to rapid population growth. This was followed by a surge in economic activity flowing from several mining booms in the late 20th and early 21st centuries that saw Perth become the regional headquarters for several large mining operations located around the state.
