 During the time of the Dutch "Culture System" a flourishing trade in colonial cash crops attracted many Chinese entrepreneurs and the Chinese influence is still evident in the batik for which Cirebon is famous.Cirebon suffered a famine in 1844, apparently triggered by a combination of drought and the shift from subsistence agriculture to cash crops, particularly indigo and sugarcane.Being on the border of Sundanese (i.e., West Java) and Javanese (i.e., Central Java) cultural regions, many of Cirebon's residents speak a dialect that is a mix of Sundanese and Javanese, known as the "Jawareh" dialect, and it is thought that the word "Cirebon" derives from the Javanese word, "caruban", meaning "mixed", a reference to the city's mix of Sundanese, Javanese, Chinese, and Arabic cultural elements.
