Before European settlement the area is said to have been occupied by the Ngiyambaa Aborigines. Explorer John Oxley camped on the present town site during his investigation of the Macquarie River in 1818. He noted an abundance of kangaroos and emus. Charles Sturt carried out further exploration in 1828-29. Cattle were grazing hereabouts by the late 1830s. Warren station was established in 1845 by Thomas Readford and William Lawson, the son of explorer William Lawson who was a member of the first European party to breach the Blue Mountains in 1813. Some say the name derives from a local Aboriginal word, meaning "strong" or "substantial". Another theory is that it represents the adoption of a contemporary English term, "warren", meaning a game park - perhaps a reference to the picturesque riverside setting where the station hut was built and to the large numbers of wildlife in the area. A small police station was built near the hut to protect the new settlers from Aborigines but there being no disturbances the police soon moved on. The hut was located by the site of a river-crossing on the main route from Dubbo. Stockmen camped here in the bend by the river, adjacent to the Warren Hole, before crossing over on the gravel bar when the water was sufficiently low. A few stayed on and a site for a township was consequently surveyed in 1860 with land sales proceeding in 1861. A post office opened in 1861, a bootmaker's shop in 1863, a store in 1866, a school in 1867, an Anglican church in 1873, the first courthouse in 1874 and the first bridge in 1875. However, the closer settlement did not really develop until the late 1880s. Warren was incorporated as a municipality in 1895 and the Warren Weir was established in 1896. The town benefited greatly with the arrival of the railway in 1898, making it the railhead for an enormous area. In general terms, its prosperity rose and fell with the price of wool. In the 1920s the town developed quite substantially. In the Great Depression the economy shrank, expanding again in the postwar years. The eternal water shortage was greatly eased when Burrendong Dam was opened in 1967, allowing the development of cotton and produce.
