Historically, the region is the cultural center of the Tidung people and was home to the Kingdom of Tidung.

## History
### Etymology

The name Tidung comes from the word tiding or tideng, which means "hills" or "mountains". Tana Tidung roughly means "Land of Tidung", referring to the region as the homeland of the Tidung people. The name of Tideng Pale town originates from two words, tideng and pale, meaning "bland", leading to the rough translation—"bland hill".

### Early history

The region was home to a native kingdom known as the Tidung Kingdom, which dated back to the 11th century. The spread of Islam in Indonesia later influenced the region. The Tidung Kingdom's existence before the spread of Islam is disputed and some argue that rather than being a kingdom, it was a tribal confederacy. Another kingdom, Berayu, also existed in the region. Berayu's first king is thought to have been related to the people of Kutai Kingdom. It was centered in what is now Malinau Kota but had influence as far as southern Nunukan. The period of tribal kingdoms, also referred to as "ancient Tidung", ended with the marriage of Queen Ikenawai and Radja Laoet from the Sultanate of Sulu in 1557. A new Islamic kingdom centered on Tarakan Island was born and referred to as the Kalkan Kingdom or the Tenggara dynasty. In 1900, the Tidung Kingdom moved its capital from Tarakan to Malinau. Between the 18th and 19th centuries, the Tidung Kingdom was one of the area's major regional powers, together with the Sultanate of Bulungan. The newly arrived Dutch disrupted the resulting rivalry. A most notable event was a royal marriage between the Sultan of Bulungan and two princesses, one from Berau and one from Tidung. The last king of Tidung, Datoe Adil, adopted anti-Dutch policies and opposed monopolies over goods in the region imposed by the Dutch. This caused disputes in internal matters, resulting in Bulungan invading Tidung with the help of the Dutch in 1916. Tana Tidung became part of the Afdeeling Tidoengschelanden (Land of Tidung Administrative District) under the Dutch East Indies and later the newly formed Indonesian republic after the Indonesian National Revolution.
The conversion of people living in the region to Islam in the 15th and 16th centuries is generally believed by archeologists to be the start of the separate identity of the Tidung people from the nearby Dayak people. It is still disputed whether to classify the Tidung people as part of the larger Dayak group or as a separate native ethnic group like the Banjar people. Meanwhile, the Tidung people were classified by Tjilik Riwut as part of the Murut people. The Tidung people often referred to themselves as Islam Dayak or Dayak Muslims.

### Post-independence

The desire of the Tidung people to have their own regency dated back to early 2000 after the fall of Suharto and the rapid decentralization that followed. On 28 November 2002, several of the region's cultural figures and politicians gathered in a hotel in Tarakan to discuss the creation of a new autonomous regency to represent their culture in areas where the majority of the Tidung people lived. The creation of a Tidung-dominated regency was realized based on Law Number 34 of 2007. The regency was inaugurated on 10 July 2007, and its first regent was sworn in on 18 December 2007. The regency was formed from three districts (kecamatan) which were formerly part of Bulungan Regency.
It had been part of the East Kalimantan province, but in 2012 became part of the newly created North Kalimantan province.
