North Sulawesi () is a province of Indonesia. It is mainly located on the Minahasa Peninsula of the island of Sulawesi, south of the Philippines and southeast of Sabah, Malaysia, but also includes various small archipelagoes situated between the Minahasa Peninsula and the southern Philippines. It borders the Philippines province of Davao Occidental and Soccsksargen regions to the north, the Maluku Sea to the east, Gorontalo (its sole land border) and the Celebes Sea to the west and the Gulf of Tomini to the southwest. The province's furthest extent, the outlying island of Miangas to its north, is the northernmost island of Indonesia, and has the country's only border with the Philippines.

The province's capital and largest city is Manado, which is also the main gateway and the economic center of the province. Other major towns include Tomohon and Bitung in the northern (Minahasa) half of the province, and Kotamobagu in the southern (Bolaang Mongondow) half. There are 41 mountains with an altitude ranging from . Geologically, the province consists mainly of young volcanic regions, with numerous eruptions and many active volcanic cones in the central Minahasa, Bolaang Mongondow and Sangihe Islands.
In the past, North Sulawesi was an area of potential spices, rice and gold which became a battleground for economic hegemony between the Portuguese, Spanish and Dutch, and also the neighbouring kingdoms. This ultimately led to political and military struggles. This region also became a trading route between west and east and also a route for the spread of Christianity, Islam and beliefs brought by Chinese merchants. The Portuguese first landed in the area at the 16th century. After decades of war between the Portuguese, the Spanish and the Dutch to control the area, the area ultimately fell to the Dutch in the 17th century. The Dutch ruled the area for three centuries, before being ousted by the Japanese on the eve of World War II. After the Japanese surrendered in 1945, the Dutch briefly regained possession of the area, before finally leaving in 1949 following the Round Table Conference, in which the Dutch recognized the newly created United States of Indonesia (RIS). Thus, North Sulawesi was incorporated into the territory of the State of East Indonesia (NIT). The NIT was finally dissolved and then merged into the RIS.
On 17 August 1950, the RIS was officially disbanded and then re-formed as the unitary state of the Republic of Indonesia. The island of Sulawesi was governed briefly as a single province, before being separated into several different provinces. Thus, the province of North Sulawesi was created on 14 August 1959. The western half of this area (at that time comprising the Gorontalo Regency and the newly created Boalemo Regency) were separated from North Sulawesi on 5 December 2000 and established as the province of Gorontalo.
Etymology The area around North Sulawesi used to be called Minahasa. The name is still used sometimes to refer to the province. The word Minahasa is etymologically derived from the words Mina-Esa (Minaesa) or Maesa which means 'being one' or 'uniting', meaning hope to unite various sub-ethnic groups of Minahasa consisting of Tontemboan, Tombulu, Tonsea, Tolour (Tondano), Tonsawang, Ponosakan, Pasan and Bantik. The word "Minahasa" itself was only used during the colonial era. "Minahasa" is generally interpreted as "having become one". Based on several historical documents, the word "Minahasa" is firstly used by J.D. Schierstein, the Dutch regent of Manado, in his report to the Governor of Maluku on 8 October 1789. The word "Minahasa" in his report is defined as Landraad or "State Council" or "Regional Council".
History
Pre-Colonial Era Archaeological research has revealed signs of human life in North Sulawesi from 30,000 years ago, based on evidence in the cave Liang Sarru on the island of Salibabu. Other evidence shows life about 6,000 years ago on the Passo Hillside Site in Kakas District and 4,000 years ago to early AD at the Liang Tuo Mane'e cave in Arangkaa on Karakelong Island.
Colonial Period At the end of the 16th century, the Portuguese and Spanish arrived in North Sulawesi. When Europeans arrived, the Ternate Sultanate had influence in North Sulawesi, frequented by Bugis traders from South Sulawesi. The wealth of Minahasa's natural resources made Manado a strategic port for European traders going to and from Maluku. The Portuguese were the first European colonizers to arrive in North Sulawesi, a Portuguese ship anchored on an island off Manado in the Kingdom of Manado in 1521. The northern islands of the peninsula were under the control of the Sultanate of Maguindanao during the time. The Spanish ship docked on the island of Talaud and Siau, on to Ternate. The Portuguese built a fort at Amurang. Spain built a Fort in Manado, giving Spain control of the Minahasa Peninsula. Resistance against Spanish occupation culminated in 1660–1664. Dutch ships landed in Manado City in 1660, assisting the Minahasa Confederation against Spain. The members of the Minahasa Confederation entered into a Trade Agreement with the VOC. This trade cooperation agreement gave the VOC monopoly on trade, gradually imposing its will, eventually leading to the 1700s resistance in Ratahan, culminating in the Dutch Minahasa-War in 1809–1811 at Tondano.
Spain had colonized the Philippines and made Minahasa a coffee plantation with imported South American coffee because of its fertile land. Manado was further developed by Spain to become a center of coffee trade for Chinese merchants. In the 16th century one of the first Indo-Eurasian communities in the archipelago appeared in Manado. The first king of Manado, Muntu Untu (1630) was half Spanish. Spain then handed over Minahasa to the Portuguese in exchange for 350,000 ducats in a treaty. The rulers of Minahasa sent Supit, Pa'at, and Lontoh to ally with the Dutch to expel the Portuguese from Minahasa. In 1655 they excelled, building their own fortress in 1658 and drove out the last Portuguese a few years later.
By the beginning of the 17th century the Dutch had overthrown the sultanate of Ternate, and began to gain influence from Spain and Portugal. In 1677 the Dutch conquered the Sangir archipelago, two years later, Robert Padtbrugge, the governor of Maluku, visited Manado. His arrival resulted in an agreement with the Minahasan chiefs who led to Dutch domination for the next 300 years although the direct rule by the Dutch only began in 1870. The Dutch helped unify the Minahasa confederation, and in 1693. Dutch influence flourished with the spreading of Christianity and European culture in the land of Minahasa. The missionary schools in Manado in 1881 were one of the first attempts of mass education in Indonesia, providing an opportunity for graduates to find employment in the civil service, military, and high positions in the Dutch East Indies government. Minahasa relations with the Dutch were often poor. Causing a war between the Dutch and Tondano in 1807 and 1809. Eventually the Dutch and Minahasa became very close, with Minahasa often referred to as the 12th Dutch province. In 1947, some Manadonese formed a political movement of Twapro, short for Twaalfde Provincie (Twelfth Province) who appealed for formal integration of Minahasa into the Kingdom of the Netherlands.
Independence
During Japanese occupation of the Dutch East Indies the Allies bombed Manado greatly in 1945. During the Indonesian War of Independence, there was a split between pro-Indonesian and pro-Dutch residents. The appointment of Sam Ratulangi as the first governor of Sulawesi then succeeded in winning Minahasan support to the Republic of Indonesia. After Indonesian independence, Indonesia was divided into 8 provinces, and Sulawesi was one of these provinces. In 1946 the State of East Indonesia was formed in Sulawesi, and later became a state within the United States of Indonesia. The State of East Indonesia was dissolved, and merged into the Republic of Indonesia as part of a then unified Sulawesi Province.
In March 1957, Sulawesi military leaders held a confrontation with the central government, with demands for greater regional autonomy. They called for more active development, a fairer distribution of taxes, assistance against Abdul Kahar Muzakkar's rebellion in South Sulawesi, and a central government cabinet headed by Sukarno and Mohammad Hatta in balance. At first the movement of the 'Permesta' (Charter of the Struggle of the Universe) was merely a movement of reform rather than a separatist movement.
Negotiations between the central government and Sulawesi military leaders prevented violence in South Sulawesi, but Minahasan leaders were not satisfied with the outcome of the agreement and the movement broke out. Fearful of southern dominance, Minahasan leaders declared their own North Sulawesi autonomous state in June 1957. At that time the central government had controlled South Sulawesi, but in the North there were no strong figures of the central government and there were rumors that the United States was arming the PRRI rebellion in Sumatra, which has links with Minahasan leaders.
The possibility of foreign intervention prompted the central government to request military assistance from southern Sulawesi. The Permesta forces were later removed from Central Sulawesi, Gorontalo, Sangihe Islands, and Morotai in Moluccas. The United States then halted resistance, and in June 1958 central government forces landed in Minahasa. The Permesta uprising ended in mid-1961.
The effects of the Sumatra and Sulawesi rebellions was ultimately counterproductive, with central government authority increasing while regional autonomy weakened, radical nationalism strengthened than pragmatic moderation, communist party power and Sukarno increased while Mohammad Hatta was weakened, with the establishing of Guided Democracy () in 1958. But the demands of the Minahasa peoples for the province of their own would not end, and in 1964 the People's Representative Council enacted Law no. 13 officially creating the province of North Sulawesi, with Manado as provincial seat. 14 August 1959 was designated as the anniversary of the province.
Since the 1998 reforms, the Indonesian government has begun to adopt laws that enhanced regional autonomy. Two years later, the city of Gorontalo and two Muslim-majority regencies of the province were separated to form Gorontalo Province.
