Tara (Drina) in the context of "Upper Drina"

The Autariatae or Autariatai (alternatively, Autariates; Ancient Greek: Αὐταριᾶται, Autariatai; Latin: Autariatae) were an Illyrian people that lived between the valleys of the Lim and the Tara, beyond the Accursed Mountains, and the valley of West Morava. Their territory was located inland from the Ardiaei and the Lake Skodra, extending east to the Dardani and north or northeast to the Triballi.

Along with the Ardiaei and the Dardani, the Autariatae are mentioned by Strabo in his Geographica as one of the three strongest Illyrian peoples in the pre-Roman Balkans. Following defeat during the Celtic invasions of the Balkans in the 4th century, a part of the Autariatae who remained in Bosnia adopted Celtic culture later in their history. Another part moved southwards and after an agreement with the Kingdom of Macedonia, 20,000 settled in the Parorbelian mountain range, in the borderlands between modern southeastern North Macedonia, northern Greece and southwestern Bulgaria.

The Drina (Serbian Cyrillic: Дрина, pronounced [drǐːna]) is a 346 km (215 mi) long river in the Balkans, which forms a large portion of the border between Bosnia and Herzegovina and Serbia. It is the longest tributary of the Sava River and the longest karst river in the Dinaric Alps which belongs to the Danube River drainage basin.

The Drina originates from the confluence of the rivers Tara and Piva, in the glen between the slopes of the Maglić, Hum and Pivska Planina mountains, between the villages of Šćepan Polje, Montenegro and Hum, Bosnia and Herzegovina.

Hum (Serbian Cyrillic: Хум) is a village and a border crossing between Bosnia and Montenegro, under the eponymous mountain at the right bank of the Tara river, in Bosnia and Herzegovina, the municipality of Foča, Republika Srpska,.

Šćepan Polje (Serbian Cyrillic: Шћепан Поље, pronounced [ʃt͡ɕɛ̂paːn pɔ̂ʎɛ]) is the name of a small settlement and the region in Plužine Municipality, northwestern Montenegro. It is the border crossing point between Montenegro and Bosnia and Herzegovina, where the Tara river forms the border between the two countries. Right across the river and the state border is the village of Hum.

The Tara River Canyon (Montenegrin: Kanjon Tare, Serbian Cyrillic: Кањон Таре; [kǎɲɔːn târɛː]), also known as the Tara River Gorge, is the river canyon of the Tara river. It is for the most part located in Montenegro, and in Bosnia and Herzegovina. The most attractive part of the canyon are the high rocks of the mountain range of Ljubišnja, which are located in the UNESCO World Heritage Site of Durmitor National Park. Also in Bosnia and Herzegovina, the canyon is designated nature park, and is called Tara Nature Park.

Known as "The Tear of Europe," the Tara River Gorge stands as the deepest canyon in continental Europe, the second deepest in Europe behind the Sulak Canyon, and also behind the Grand Canyon for third deepest globally.
