The earliest known inhabitants of what is today Azerbaijan were the Caucasian Albanians, a Caucasian-speaking people who appear to have been in the region prior to the host of peoples who would eventually invade the Caucasus. Historically Azerbaijan has been inhabited by a variety of peoples, including Persians, Greeks, Romans, Armenians, Arabs, Turks, Mongols and Russians.


The first kingdom to emerge in the territory of present-day Republic of Azerbaijan was Mannae in the 9th century BC, lasting until 616 BC when it became part of the Median Empire, which later became part of the Persian Empire in 549 BC. The satrapies of Atropatene and Caucasian Albania were established in the 4th century BC and included the approximate territories of the present-day Azerbaijan nation-state and southern parts of Dagestan.

Islam spread rapidly in Azerbaijan following the Arab conquests in the 7th–8th centuries. After the power of the Arab Khalifate waned, several semi-independent states have been formed, the Shirvanshah kingdom being one of them. In the 11th century, the conquering Seljuk Turks became the dominant force in Azerbaijan and laid the ethnic foundation of contemporary Azerbaijanis. In the 13-14th centuries, the country experienced Mongol-Tatar invasions.

Azerbaijan was part of the Safavid Persian Empire during the 15th–18th centuries. It also underwent a brief period of feudal fragmentation in the mid-18th to early 19th centuries, and consisted of independent khanates. Following the two wars between Qajar Persian Empire, as well as the Ganja, Guba, Baku and other independent khanates, and the Russian Empire, Azerbaijan was acquired by Russia through the Treaty of Gulistan in 1813, and the Treaty of Turkmenchay in 1828, and several earlier treaties between the Russian tsar and the khans concluded in the first decade of the 19th century. In 1873, oil ("black gold") was discovered in the city of Baku, Azerbaijan's future capital. By the beginning of the 20th century almost half of the oil reserves in the world had been extracted in Baku.



After the collapse of the Russian Empire during World War I, Azerbaijan together with Armenia and Georgia became part of the short-lived Transcaucasian Democratic Federative Republic. When the republic dissolved in May 1918, Azerbaijan declared independence as the Azerbaijan Democratic Republic. The ADR was the first Muslim republic in the world and lasted only two years, from 1918 to 1920, before the Soviet Red Army invaded Azerbaijan. In March 1922, Azerbaijan, along with Armenia and Georgia, became part of the Transcaucasian SFSR within the newly-formed Soviet Union. In 1936, the TSFSR was dissolved and Azerbaijan became constituent republic of the USSR as the Azerbaijan SSR.

During World War II, Nazi Germany invaded the Soviet Union. The primarily objective of Adolf Hitler's Operation Edelweiss offensive was to capture Azerbaijan's oil-rich capital of Baku. For the war effort, Soviet oil workers were obliged to work non-stop and citizens were to dig entrenchments and antitank obstacles into order to block a possible enemy invasion. However, Operation Edelweiss was unsuccessful. The German army was at first stalled in the mountains of Caucasus, then decisevely defeated at the Battle of Stalingrad.

In 1990, Azeris gathered to protest Soviet rule and push for independence. The demonstrations were brutally suppressed by Soviet intervention in what Azeris today refer to as Black January. In 1991, however, Azerbaijan re-established its independence upon the collapse of the Soviet Union. Unfortunately, the early years of its independence were overshadowed by a war with Armenia and separatist Armenians over the region of Nagorno-Karabakh. Despite a cease-fire in place since 1994, Azerbaijan has yet to resolve its conflict with Armenia over the predominantly ethnic Armenian territory. Since the end of the war, Azerbaijan lost control of 14 - 16% of its territory including Nagorno-Karabakh itself. As a result of the conflict, both countries faced problems with refugees and internally displaced persons as well as economic hardships.

However, former Soviet Azeri leader Heydar Aliyev changed this pattern in Azerbaijan and sought to exploit its wealthy oil reserves in Baku, something that Azerbaijan has become famous for. Aliyev also cleaned up gambling and was able to cut down the country's unemployment rate substantially. He also sought closer relations with Turkey while simultaneously making efforts to resolve the Karabakh conflict peacefully with Armenia. However, the political situation in Azerbaijan remains tense especially after Aliyev, upon his death, selected his son Ilham to assume the duties of president. Azeri opposition forces are not satisfied with this new dynastical succession and are pushing for a more democratic government.

Azerbaijan is divided into fifty-nine raions (rayonlar; sing. - rayon), 11 cities (şəhərlər; sing. - şəhər), and one autonomous republic (muxtar respublika), Nakhichevan. Nakhichevan itself is subdivided into seven rayons and one city. The city of Baku is the capital of Azerbaijan.
