Bulgaria, officially known as the Republic of Bulgaria, is a fascinating country in Southeast Europe. It sits on the eastern part of the Balkan Peninsula, south of the Danube River and west of the Black Sea. Bulgaria shares borders with Greece, Turkey, Serbia, North Macedonia, and Romania. It covers about 110,994 square kilometers, making it the tenth largest country in the European Union. Sofia is Bulgaria's capital and largest city. Other important cities are Burgas, Plovdiv, and Varna.

The land where Bulgaria is today has a very long history. One of the first groups of people lived there around 6,500 BC. Over many centuries, different ancient groups like the Thracians and Romans lived and fought in this area. Around the 6th century, the early Slavs settled here. Later, in the late 7th century, a group called the Bulgars, led by Asparuh, arrived. They created the First Bulgarian Empire in 681 AD. This empire became very powerful and helped create the Cyrillic script, which is still used today. After a long time, the Byzantine Empire conquered the First Bulgarian Empire. But in 1185, a new Second Bulgarian Empire was formed. It grew strong under leaders like Ivan Asen II. Eventually, this empire also faced challenges and fell under the rule of the Ottoman Empire in 1396, which lasted for almost 500 years.

In 1878, after a war, the third Bulgarian state was formed. It declared full independence from the Ottoman Empire in 1908. In the 20th century, Bulgaria was involved in both world wars. After World War II, in 1946, Bulgaria became a socialist state. This period ended in 1989, when the country began its journey to become a democracy.

Since 1991, Bulgaria has been a parliamentary republic with 28 regions called provinces. Its economy is strong and focuses on services, manufacturing, mining, and agriculture. Bulgaria is important for natural gas and oil pipelines because of its location near the Black Sea. Today, Bulgaria is a member of the European Union and NATO. It also belongs to the Schengen Area and the eurozone.

Exploring Bulgaria's Past

What's in a Name? The Origin of "Bulgaria"

The name Bulgaria comes from the Bulgars. They were a group of people who founded the First Bulgarian Empire. Historians believe their name might come from an old word meaning "to mix" or "to stir." This could refer to them being "disturbers" or a "mixed group" of people.

Ancient Times and Early Settlements

The earliest signs of human life in Bulgaria date back about 150,000 years. Around 6,500 BC, the Karanovo culture thrived here, known for its farming. The Varna culture (around 5,000 BC) was famous for creating the world's oldest golden jewelry. This treasure helps us understand ancient societies.

The Thracians were an important ancient group in the Balkans. They were skilled metalworkers. The Roman Empire took control of the region in 45 AD. Later, around the 6th century, Slavic tribes settled in these lands.

The First Bulgarian Empire: A Powerful Beginning

In 680 AD, the Bulgars, led by Khan Asparukh, arrived and formed the First Bulgarian Empire. This empire was officially recognized by the Byzantine Empire in 681 AD. It became a major power in the Balkans.

Under leaders like Krum and Boris I, Bulgaria grew stronger. Boris I made Eastern Orthodox Christianity the official religion in 864. The Cyrillic alphabet was developed in the capital, Preslav. This alphabet helped unite the Slavs and Bulgars. A "golden age" of culture and power began under Simeon the Great. The First Bulgarian Empire lasted until 1018, when the Byzantines conquered it.

The Second Bulgarian Empire: A New Era

After some time, a new Bulgarian state was formed in 1185 by nobles Ivan Asen I and Peter IV. This was the Second Bulgarian Empire, with its capital at Tarnovo. It reached its peak under Ivan Asen II (1218–1241), expanding its borders and seeing culture flourish.

However, after many conflicts, the empire weakened. By the 14th century, it broke into smaller parts. These smaller states were then conquered by the Ottoman Turks.

Ottoman Rule: A Long Period of Change

Battle of Nicopolis
The Battle of Nicopolis in 1396 marked the end of medieval Bulgarian statehood.

The Ottomans completed their conquest of Bulgarian lands by 1396. This began a period of nearly five centuries of Ottoman rule. During this time, Bulgarians faced new taxes and their culture was suppressed.

As the Ottoman Empire weakened, other European powers like Austria and Russia became interested in helping Bulgarian Christians. This led to several uprisings. The Russo-Turkish War of 1877–78 finally brought an end to Ottoman rule in Bulgaria.

The Third Bulgarian State: Modern Bulgaria

The Treaty of San Stefano in 1878 created an autonomous Bulgarian principality. However, other European powers changed these borders with the Treaty of Berlin. This created a smaller Principality of Bulgaria. Bulgaria declared full independence from the Ottoman Empire on 5 October 1908. This day is now a national holiday.

In the early 20th century, Bulgaria was involved in several conflicts, including two Balkan Wars and World War I. After World War I, Tsar Boris III ruled the country. Bulgaria joined the Axis powers in World War II but saved its Jewish population from concentration camps.

After World War II, in 1946, Bulgaria became a socialist state under Soviet influence. This period saw rapid industrial growth. In 1989, the Communist Party gave up its power, and Bulgaria began its transition to a democracy.

Since 1991, Bulgaria has adopted a democratic constitution. It joined NATO in 2004 and the European Union in 2007. Bulgaria continues to work on improving its economy and society.

The government has three main parts: the legislative (makes laws), executive (carries out laws), and judicial (interprets laws). The president is the head of state and commander-in-chief of the armed forces. The president can suggest changes to laws, but the parliament can override this.

The National Assembly has 240 members, called deputies. They are elected for four-year terms. The National Assembly makes laws, approves the budget, and chooses the prime minister.

Legal System: Rules and Justice

Bulgaria uses a civil law legal system. The Ministry of Justice oversees the courts. The highest courts are the Supreme Administrative Court and the Supreme Court of Cassation. They ensure laws are applied correctly. The Supreme Judicial Council manages the system and appoints judges.

Law enforcement is handled by the Ministry of the Interior. The General Directorate of National Police (GDNP) works to prevent crime and keep public order. The Border Police Service and National Gendarmerie also help with security.

Administrative Divisions: How Bulgaria is Organized

Bulgaria is divided into 28 provinces, plus the capital city, Sofia City. Each province is named after its main city. These provinces are further divided into 265 municipalities. Mayors lead the municipalities and are elected for four-year terms.
