In contrast, the earliest exploitation and working of gold occurs in the Balkans during the mid-fifth millennium BC, several centuries after the earliest known copper smelting. This is demonstrated most spectacularly in the various objects adorning the burials at Varna, Bulgaria (Renfrew 1986; Highamet al. 2007). In contrast, the earliest gold objects found in Southwest Asia date only to the beginning of the fourth millennium BC as at Nahal Qanah in Israel (Golden 2009), suggesting that gold exploitation may have been a Southeast European invention, albeit a short-lived one.

The conquest of the Balkans and the rise of the Bulgarian Empire was not a disaster for the indigenous population and its material and spiritual culture. The settlers and the local Romanised or semi-Romanised Thraco-Illyrian Christians influenced each other's way of life and socio-economic organization, as well as each other's cultures, language and religious outlook.

Among the scales which have come to the Balkans from Asia, the pentatonic is one of the most widely used in Bulgaria. Whether it came from China or Japan, as Dobri Hristov suggests

Bulgaria gave the highest priority to scientific and technological advancement and the development of trade skills appropriate to an industrial state. In 1948 approximately 80 percent of the population drew their living from the soil, but by 1988 less than one-fifth of the labour force was engaged in agriculture, with the rest concentrated in industry and the service sector.

In international sports competition, Bulgarians have excelled in tennis, wrestling, boxing, and gymnastics, but the country's greatest repute may be in weight-lifting. ... Fans of football (soccer), the most popular sport in Bulgaria, were buoyed by the success of the national team in the 1994 World Cup, when it advanced to the semi-final match under the leadership of forward Hristo Stoichkov. The premier league in Bulgaria has 16 teams, of which four play in Sofia: CSKA, Levski, Slavia, and Lokomotiv.

In contrast, the earliest exploitation and working of gold occurs in the Balkans during the mid-fifth millennium BC, several centuries after the earliest known copper smelting. This is demonstrated most spectacularly in the various objects adorning the burials at Varna, Bulgaria (Renfrew 1986; Highamet al. 2007). In contrast, the earliest gold objects found in Southwest Asia date only to the beginning of the fourth millennium BC as at Nahal Qanah in Israel (Golden 2009), suggesting that gold exploitation may have been a Southeast European invention, albeit a short-lived one.
