Precolonial Nias island, together with groups of other islands off the western coast of Sumatra, was mentioned by
Ptolemy in 150 CE as "Barus islands". Nias had well-established trade contacts with Arab and Chinese traders since around the seventh century. Archeological evidence shows humans have inhabited the island for 12,000 years. Remains of tools were found in Tögi Ndrawa cave by Indonesian archeologists from
Medan in August 1999. The excavation shows sign of
Mesolithic culture and that the cave was still inhabited until around 700 years ago. In 1668, the
Dutch East India Company made agreements with village chiefs around the location of modern-day Gunungsitoli city and the
Hinako islands. The company settled the region and built several warehouses The Dutch were only able to start a significant military campaign against Nias tribes in 1900 and subjugated the entire island by 1914. Nias was one of the last regions of the Indonesian archipelago by to be conquered by the
Dutch East Indies.
Mid-to-late 20th century Gunungsitoli was one of two locations on Nias where Dutch authorities held German prisoners during
World War II. The prisoners were formerly part of a larger German prisoner group aboard the
SS Van Imhoff, which was sunk by Japanese bombers off the west coast of Sumatra. Upon hearing news about Japanese attacks on Sumatra, the German prisoners planned a coup against the Dutch colonial authority in the city. The prisoners tried to persuade native police, known as
Veldpolities, to revolt. At the time, the city was home to around 60 German prisoners. On 29 March 1942, the native police revolted by shooting Dutch residents and imprisoning Dutch officials, and the city was quickly occupied. On 17 April 1942, the Japanese military landed in the city and was welcomed by the German prisoners, who took over the city. By 24 April 1942, all German prisoners had left the island and the administration was handed over to the Japanese until the end of World War II. The banknotes were known as ORIPDA-Nias (Regional Money of Republic Indonesia-Nias). The republican government of Nias was evacuated from Gunungsitoli in the aftermath. Despite these improvements the boom was short-lived. The city's infrastructure has been improved and development of the tourist industry has been a particular focus of both local and central government. Gunungsitoli has been proposed as the capital of the newly proposed
Nias Islands Province, which is projected to be separated from North Sumatra. As of 2023, however, the creation of the new province and other proposed new provinces and regencies has been halted due to the
COVID-19 pandemic which put strain on government budgets, as well as by a government moratorium since 2013 on the creation of new provinces and regencies. == Geography ==
