Ancient times
Pliny, Appian and Ptolemy mentioned the Docleatae as living in the maritime region, holding the town of Doclea (old Podgorica). In 9 AD the Romans conquered the region. Slavs colonized the area in the 6th century, and had by the 10th century formed a semi-independent principality called Duklja, that was predominantly tied to Medieval Serbia, and to lesser degree, Byzantium, and Bulgaria.
Middle Ages
Duklja gained its independence from the Byzantine Empire in 1042. Over the next few decades, it expanded its territory to neighbouring Rascia and Bosnia and also became recognised as a kingdom.

For a short time Montenegro existed as a separate autonomous sanjak in 1514–1528, another version of which existed again between 1597 and 1614.
Ottoman rule and Metropolitanate
In the 16th century Montenegro developed a form of unique autonomy within the Ottoman Empire with Montenegrin clans being free from certain restrictions. Nevertheless the Montenegrins refused to accept Ottoman rule and in the 17th century raised numerous rebellions, culminating with the defeat of the Ottomans in the Great Turkish War at the end of that century.
Montenegro became a theocracy led by the Metropolitans, flourishing since the Petrović-Njegoš became the traditional prince-bishops (whose title was
