Buleleng was founded as a kingdom by Gusti Panji Sakti, who ruled c. 1660-c. 1700. He is commemorated as a heroic ancestor figure who expanded the power of Buleleng to Blambangan on East Java. The kingdom was weakened during its successors and fell under the suzerainty of the neighbouring Karangasem kingdom in the second half of the 18th century. It was headed by an autonomous branch of the Karangasem Dynasty in 1806–1849.
The Dutch attacked Buleleng in 1846, 1848, and 1849, and defeated it on the last occasion. Buleleng was incorporated into the Dutch colonial system and lost its autonomy in 1882. In 1929 a descendant of Gusti Panji Sakti, the renowned scholar Gusti Putu Jelantik, was appointed regent by the Dutch. He died in 1944, during the Japanese occupation of the Dutch East Indies. His son was a well-known novelist, Anak Agung Nyoman Panji Tisna. In 1947, Anak Agung Pandji Tisna surrendered the throne to his younger brother, Anak Agung Ngurah Ketut Djelantik, known as Meester Djelantik, until 1950. In 1949–50 Buleleng, like the rest of Bali, was incorporated into the unitary republic of Indonesia.

Previously, the area in North Bali or Den Bukit was never united, they fought and attacked each other, until finally this area was united by a man named I Gusti Anglurah Panji Sakti from Dalem Sagening Dynasty by uniting all the areas in North Bali that were in conflict.
Then I Gusti Anglurah Panji Sakti controlled the entire area of North Bali/Den Bukit and began to expand his territory to Jembrana, Karangasem, Bangli, Tabanan and even to Banyuwangi in East Java. After the death of I Gusti Ngurah Panji Sakti in 1704, the Buleleng Kingdom began to falter due to the struggle for power, plus the colonial areas began to rebel and put up resistance such as the Jembrana rebellion in West Bali and the Karangasem resistance in East Bali.

In 1732, Buleleng was controlled by the Mengwi Kingdom, but they regained their independence in 1752. Subsequently, the Buleleng Kingdom fell under the power of the king of Karangasem in 1780. The King of Karangasem, I Gusti Gede Karang built a palace called "Puri Singaraja". The next king to rule was his son named I Gusti Pahang Canang who ruled until 1821. Karangasem's power then weakened, and there were several changes of king. In 1825, I Gusti Made Karangasem ruled with his patih, I Gusti Ketut Jelantik until it was conquered by the Dutch in 1849.

In 1846, Buleleng was attacked by Dutch troops, but it met with fierce resistance from the Buleleng community led by the warlord (patih) I Gusti Ketut Jelantik. In 1848, Buleleng was again attacked by Dutch navy troops at Fort Jagaraga. In the third attack, in 1849, the Dutch were finally able to destroy Fort Jagaraga so that Buleleng could be defeated by the Dutch. Since then, Buleleng was controlled by the Dutch East Indies colonial government, the Buleleng region was made a "Swapraja" with the Dutch king as its ruler, the king of Buleleng from the Panji Sakti dynasty was then appointed as regent under colonial supervision.
