The Makassar or Makassarese people are an ethnic group that inhabits the southern part of the South Peninsula, Sulawesi (formerly Celebes) in Indonesia. They live around Makassar, the capital city of the province of South Sulawesi, as well as the Konjo highlands, the coastal areas, and the Selayar and Spermonde islands. They speak Makassarese, which is closely related to Buginese and also a Malay creole called Makassar Malay. Makassar people have a history of migration and exploration that extends beyond their homeland in South Sulawesi. Makassar sailors, were skilled navigators and traders who ventured out into the vast waters of the Indonesian archipelago and beyond. One notable area of Makassar migration was to the northern coast of Australia, particularly what is now known as the Northern Territory, They established trade relationships with the Aboriginal communities, primarily for the purpose of harvesting and processing sea cucumber. Makassar sailors also engaged in trade and exploration throughout Southeast Asia. They established trade networks, especially in the Malay Peninsula, the Philippines, and Borneo. The Makassan influence can still be seen in the cultural practices and traditions of some of these regions. The Makassar are an ethnic group originally from the southern coast of the island of Sulawesi. Their exploratory spirits have led to successful overseas explorations. This is exemplified by the Kingdom of Gowa (14-17th century), which succeeded in forming a vast Islamic empire with a large and strong naval force. Its territory included almost the entire island of Sulawesi, eastern Kalimantan, East Nusa Tenggara, part of West Nusa Tenggara, part of Maluku and some small surrounding islands. The Makassar people made treaties with Bali and cooperated with Malacca and Banten, as well as some other kingdoms within the archipelago. Similar treaties were sometimes struck with foreign powers, especially with the Portuguese. However, until its fall, Gowa was also engaged in ongoing wars with the Netherlands.
