Bulgaria
In the north of Bulgaria, the River Danube forms a natural border with Romania. Just south of the river, the rolling Danubian Plain stretches out across the northern part of the country. Apart from the Maritsa valley in the south, the rest of Bulgaria is dominated by two mountain chains. The high, rounded Balkan Mountains stretch across the middle of the country in a long chain. Rising in the southwest are the Rhodopes, where some of the highest peaks on the Balkan Peninsula are found. Their slopes are covered by coniferous forests. Bulgaria has a continental climate; winters are cold, while summers are warm and mild.
People
Most of the population are descendants of the Bulgars, a Southern Slavic people who settled in the region in the 6th century. Their language, Bulgarian, is similar to Serbo-Croat and Russian. It uses an alphabet called the Cyrillic alphabet, invented in Bulgaria in the 9th century. Bulgaria is a mainly Orthodox Christian country. About one tenth of its population is Turkish and Muslim; in the south of the country there is also a small community of Bulgarian (Slavic) Muslims called Pomaks.
Bulgaria has a shrinking population: in the early 1990s, a financial collapse prompted over a million people to leave the country in search of work elsewhere. They went to nearby EU countries such as Italy, Greece, Cyprus and Austria. Today, a third of all households in Bulgaria are home to just one person.
Economy
Heavy industries, such as iron and steel production, are still important to Bulgaria’s economy. Just over a third of people work in manufacturing industries making metals, machinery and cars. Farming is also a major industry. More than half of all Bulgaria’s land is used to grow crops such as wheat, oats, rye and sugar beet.
In recent years, Bulgaria has become popular with tourists, who visit the Black Sea coast to enjoy its sandy beaches and marvel at its ancient ruins. During winter, thousands of skiers from all over the world flock to the slopes of the snowy Pirin Mountains, boosting the economy of Bulgaria’s mountain villages.
Roses
Roses are one of Bulgaria’s main crops. For centuries, farmers have planted fields of damask roses on the southern slopes of the Balkan Mountains, in a region known as the “Rose Valley”. When the flowers appear, between May and June, the roses are carefully cut and gathered at dawn—before the sun has a chance to dry them out. Their petals are quickly picked and processed with water and steam to make attar, an oil used to make perfume.
