The name ''Moldova'' is derived from the Moldova River; the valley of this river served as a political centre at the time of the foundation of the Principality of Moldavia in 1359. The origin of the name of the river remains unclear. According to a legend recounted by Moldavian chroniclers Dimitrie Cantemir and Grigore Ureche, Prince Dragoș named the river after hunting an aurochs: following the chase, the prince's exhausted hound ''Molda'' drowned in the river. The dog's name, given to the river, extended to the Principality.
