History of Bulgaria
The history of Bulgaria goes back to 1,400,000 BCE,  where first signs of human culture were discovered. Organised prehistoric societies in Bulgarian lands include the Neolithic Hamangia culture, Vinča culture and the eneolithic Varna culture (fifth millennium BCE). Europe's most ancient cities were located in Bulgaria; one of them, Plovdiv, is still inhabited. The Varna Necropolis offers insights for understanding the social hierarchy of the earliest European societies. The first Bulgarian state was funded in 681. It was conquered eventually by the Byzantine Empire but later restored. In the years 1393-1887, Bulgaria formed a part of the Ottoman Empire, and on 3 March 1878 it declared its independence, Based on that date Bulgarians celebrate Bulgaria's national day each year.. The third republic was democratic until 1946. Between 1946-1990, Bulgaria was a communist country.
Bulgaria has recovered from an economic recession that happened around 1996 and is now rapidly improving economically. Since 2004 the Bulgarian economy has grown by an average of 6% per year and developed inflation. It is unclear what effect the current world recession will have. Improvements in reducing corruption and crime have been made. Still in 2012 unemployment was just over 12% and corruption is still a problem.
