Betawi people, or Betawis (Orang Betawi in Indonesian, meaning "people of Batavia"), are an Austronesian ethnic group native to the city of Jakarta and its immediate outskirts, as such often described as the native inhabitants of the city. They are the descendants of the people who inhabited Batavia (the colonial name of Jakarta) from the 17th century onwards.
However, the term "native" itself is questionable, since it is probable that the Betawi people emerged in the 18th century as an amalgamation of various ethnic groups into Batavia.
The Betawis are one of the most recently formed ethnic groups in Indonesia. They are a creole ethnic group in that their ancestors came from various parts of Indonesia and abroad. Before the 19th century, the self-identity of the Betawi people was not yet formed. The name Betawi are adopted from the native rendering of the term "Batavia" city which is originally named after the Batavi, an ancient Germanic tribe.
In the 17th century, Dutch colonial authorities began to import servants and labours from all over the archipelago into Batavia. One of the earliest were Balinese slaves bought from Bali and Ambonese mercenaries. Subsequently, other ethnic groups followed suit; they were Malays, Sundanese, Javanese, Minangkabaus, Buginese, and Makassar. Foreign and mixed ethnic groups were also included; such as Indos, Mardijkers, Portuguese, Dutch, Arabs, Chinese and Indians, who were originally brought to or attracted to Batavia to work.
Originally, circa 17th to 18th century, the dwellers of Batavia were identified according to their ethnics of origin; either Sundanese, Javanese, Malays, Ambonese, Buginese-Makassar, or Arabs and Chinese. This was shown in the Batavia census record that listed the immigrant's ethnic background of Batavian citizens. They were separated into specific ethnic-based enclaves kampungs, which is why in today's Jakarta there are some regions named after ethnic-specific names such as: Kampung Melayu, Kampung Bali, Makassar, and Kampung Ambon.
