The greater Darwin area is the ancestral home of the Larrakia people. On 9 September 1839, sailed into Darwin Harbour during its survey of the area. John Clements Wickham named the region "Port Darwin" in honour of their former shipmate Charles Darwin, who had sailed with them on the ship's previous voyage, which ended in October 1836. The settlement there became the town of Palmerston in 1869, but it was renamed Darwin in 1911. The city has been almost entirely rebuilt four times, following devastation caused by the 1897 cyclone, the 1937 cyclone, Japanese air raids during World War II, and Cyclone Tracy in 1974.
