The Sundanese (Sundanese: Urang Sunda, Sundanese script: ᮅᮛᮀ ᮞᮥᮔ᮪ᮓ) are an ethnic group originating from the western part of the island of Java, Indonesia, with the term Tatar Pasundan which covers the administrative areas of the provinces of West Java, Banten, Jakarta and the western region of Central Java (part of area of Cilacap Regency, Banyumas Regency, Brebes Regency).
Significant Sundanese populations can also be found in other provinces in Indonesia and abroad, such as in Japan, Taiwan and other countries, as a place for the Sundanese diaspora.
The identity that unites the Sundanese people is their language and culture. The Sundanese are known to have properties that are optimistic, friendly, polite, cheerful and homely. The Portuguese noted in the Suma Oriental that the Sundanese were honest and brave. The Sundanese are also the first ethnic group to carry out parallel diplomatic relations with other nations.
Sang Hyang Surawisesa, or King Samian, was the first king in the archipelago to carry out diplomatic relations with other nations in the 15th century with the Portuguese in Malacca. The Sunda-Portugal Treaty Inscription details are the results of his diplomacy.
In addition to achievements in politics (especially at the beginning of Indonesia's independence) and economics, achievements that are immensely encouraging are in the field of culture, namely the number of singers, musicians, actors and actresses from the Sundanese ethnicity who have achievements at the national and international levels.
