Albanians also refer to Kosovo as Dardania, the name of an ancient kingdom and later Roman province, which covered the territory of modern-day Kosovo. The name is derived from the ancient tribe of the Dardani, possibly related to a Proto-Albanian word "dardā", which means "pear". The former Kosovo President Ibrahim Rugova had been an enthusiastic backer of a "Dardanian" identity and the Kosovan flag and presidential seal refer to this national identity. However, the name "Kosova" remains more widely used among the Albanian population.
