I feel the need to divide that into two categories; formal relationships and informal relationships. In this
case, formal relations are based on politics and military, that is, relationships that were built in the 16th
century. The farther away the year, the more cryptic the sources will be. But since the 1530s, Acehnese
envoys began to appear in Istanbul, and they were involved in Aceh-Ottoman cooperation. They came to
ask for military assistance to fight Portuguese colonialism in the region. By conducting literature study,
verification, and interpretation, the author returns to the description of a brief history through the sources
written when the Ottoman Turks were still standing. In Muhamad Farid Beik's work, which tells the
Ottoman Turkish Government sent a complete fleet to the Archipelago complete with the crew and others.
This means that formal relations were established before 1530 AD. After that, there had been diplomatic
and military relations between the two sultanates. Turkish cannons that were brought to Aceh are still in
the Dutch museum. The relationship between the Ottoman Turks and the Nusantara was not only based
on benefit but also based on panic Islamism in facing the same enemy, namely the Portuguese colonialists.
When Indonesia faced the Dutch, the Ottoman Turks still provided informal assistance through volunteers
due to Western pressure, mainly the British.
