Budva (Будва, bûːdv̞a or bûdv̞a) is a Montenegrin town on the Adriatic Sea. It has 19,218 inhabitants, and it is the centre of Budva Municipality. The coastal area around Budva, called the Budva Riviera, is the center of Montenegrin tourism, known for its well-preserved medieval walled city, sandy beaches and diverse nightlife. Budva is 2,500 years old, which makes it one of the oldest settlements on the Adriatic coast.
In Montenegrin, the town is known as Будва or Budva; in Italian and Latin as Budua; in Albanian as Budua, and in (classical/ancient) Greek as Bouthoe (Βουθόη).
Extensive archaeological evidence places Budva among the oldest urban settlements of the Adriatic coast. Substantial documentary evidence provides historical references dating back to the 5th century BC.
A legend recounts that Bouthoe (Βουθόη - Bouthoē) was founded by Cadmus, the founder of Thebes, Greece, when exiled out of Thebes, finding a shelter in this place for him and his wife, goddess Harmonia.
Greek colonization of Adriatic began in the 4th century BC, when an Emporium was established on the site of Budva. In the 2nd century BC, the area of Budva became part of the Roman Empire. Upon the fall of the Empire and its division into east and west, the defensive barrier which separated the two powers happened to run across this area, subsequently making a lasting impact on the history and culture of this town.
In the 6th century, Budva was part of the Byzantine Empire, and in the following two centuries, Slavs and, to a lesser extent, Avars began to arrive in the area, mixing with the native Roman population. Budva bay was reportedly known as Avarorum sinus (Avar bay') during the Avar incursions. In 841, Budva was sacked by Muslim Saracens, who devastated the area.
In the early Middle Ages, Budva was reigned by a succession of Doclean kings, as well as Serbian and Zetan aristocrats.
1200, it became the see of a Roman Catholic Diocese of Budua, which lasted until 1828 and was nominally revived as a Latin titular bishopric.
