Siege Of Serdica (809)
The siege of Serdica ( bg, Обсадата на Сердика) took place in the spring of 809 at modern Sofia, Bulgaria. As a result, the city was annexed to the Bulgarian State and remained so until the fall of the First Bulgarian Empire. Historical background After the destruction of the Avar Khaganate, Khan Krum turned his gaze to the southwest to liberate the Slavs who populated the valley of the Struma River and Macedonia. The main obstacle to Krum's plan, however, was the strong Byzantine fortress at Serdica. The Byzantine Empire, however, was the first to initiate conflict. In 807, the Byzantine emperor Nikephoros I marched against Bulgaria but was soon forced to return to Constantinople due to a mutiny of his troops at Adrianople. The following year, the Bulgarians, in response to an equestrian raid in the valley of the Struma River, defeated the Byzantines and captured their baggage. The siege In the spring of 809, Krum took the offensive and surprised the Byzan ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Macedonia () is a geographical and historical region of the Balkan Peninsula in Southeast Europe.

Sieges Involving The First Bulgarian Empire
A siege is a military blockade of a city, or fortress, with the intent of conquering by attrition, or a well-prepared assault. This derives from la, sedere, lit=to sit. Siege warfare is a form of constant, low-intensity conflict characterized by one party holding a strong, static, defensive position. Consequently, an opportunity for negotiation between combatants is common, as proximity and fluctuating advantage can encourage diplomacy. The art of conducting and resisting sieges is called siege warfare, siegecraft, or poliorcetics. A siege occurs when an attacker encounters a city or fortress that cannot be easily taken by a quick assault, and which refuses to surrender. Sieges involve surrounding the target to block the provision of supplies and the reinforcement or escape of troops (a tactic known as "investment"). This is typically coupled with attempts to reduce the fortifications by means of siege engines, artillery bombardment, mining (also known as sapping), or the use ...

9th Century In Bulgaria
9 (nine) is the natural number following and preceding . Evolution of the Arabic digit In the beginning, various Indians wrote a digit 9 similar in shape to the modern closing question mark without the bottom dot. The Kshatrapa, Andhra and Gupta started curving the bottom vertical line coming up with a -look-alike. The Nagari continued the bottom stroke to make a circle and enclose the 3-look-alike, in much the same way that the sign @ encircles a lowercase ''a''. As time went on, the enclosing circle became bigger and its line continued beyond the circle downwards, as the 3-look-alike became smaller. Soon, all that was left of the 3-look-alike was a squiggle. The Arabs simply connected that squiggle to the downward stroke at the middle and subsequent European change was purely cosmetic. While the shape of the glyph for the digit 9 has an ascender in most modern typefaces, in typefaces with text figures the character usually has a descender, as, for example, in . The mod ...

History Of Sofia
The history of Sofia, Bulgaria's capital and largest city, spans thousands of years from Antiquity to modern times, during which the city has been a commercial, industrial, cultural and economic centre in its region and the Balkans. Antiquity A Neolithic settlement discovered in Slatina, north-eastern Sofia, is dated to be from the 6th millennium BC. Another Neolithic settlement around the National Art Gallery is traced to the 3rd–4th millennium BC. The earliest tribes who settled were the Thracian Tilataei. In the 500s BC, the area became part of a Thracian union, the Odrysian kingdom. In 339 BC Philip II of Macedon destroyed and ravaged the town. The Celtic tribe Serdi gave their name to the city. The earliest mention of the city comes from an Athenian inscription from the 1st century BC, attesting ''Astiu ton Serdon'', i.e. city of the Serdi. A local inscription and Dio Cassius recorded that the Roman general Crassus subdued the Serdi and beheaded the captives. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Nikephoros I
Nikephoros I or Nicephorus I ( gr, Νικηφόρος; 750 – 26 July 811) was Byzantine emperor from 802 to 811. Having served Empress Irene as '' genikos logothetēs'', he subsequently ousted her from power and took the throne himself. In reference to his career before becoming emperor, he is sometimes surnamed "the Logothete" (ὁ Λογοθέτης) and "Genikos" or "Genicus" (ὁ Γενικός). Nikephoros pursued wars against the Arabs and Bulgarians, with mixed results; while invading Bulgaria he was defeated and killed at the Battle of Pliska. Background Sources outside the Byzantine context, including Michael the Syrian, al-Tabari, and Mas'udi, preserve the tradition that Nikephoros was of Ghassanid Arab origin. al-Tabari claims that he derived this information from Byzantine sources, but no surviving Byzantine chronicle makes explicit mention of the emperor's ethnic background. The modern scholar Paul Julius Alexander suggests that al-Tabari did transmit informat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Struma River
The Struma or Strymónas ( bg, Струма ; el, Στρυμόνας ; tr, (Struma) Karasu , 'black water') is a river in Bulgaria and Greece. Its ancient name was Strymṓn (Greek: Στρυμών ). Its drainage area is , of which in Bulgaria, in Greece and the remaining in North Macedonia and Serbia. It takes its source from the Vitosha Mountain in Bulgaria, runs first westward, then southward, forming a number of gorges, enters Greek territory at the Kula village. In Greece it is the main waterway feeding and exiting from Lake Kerkini, a significant centre for migratory wildfowl. The river flows into the Strymonian Gulf in Aegean Sea, near Amphipolis in the Serres regional unit. The river's length is (of which in Bulgaria, making it the country's fifth-longest and one of the longest rivers that run solely in the interior of the Balkans.

Sofia
Sofia ( ; bg, София, Sofiya, ) is the capital and largest city of Bulgaria. It is situated in the Sofia Valley at the foot of the Vitosha mountain in the western parts of the country. The city is built west of the Iskar river, and has many mineral springs, such as the Sofia Central Mineral Baths. It has a humid continental climate. Being in the centre of the Balkans, it is midway between the Black Sea and the Adriatic Sea, and closest to the Aegean Sea. Known as Serdica in Antiquity and Sredets in the Middle Ages, Sofia has been an area of human habitation since at least 7000 BC. The recorded history of the city begins with the attestation of the conquest of Serdica by the Roman Republic in 29 BC from the Celtic tribe Serdi. During the decline of the Roman Empire, the city was raided by Huns, Visigoths, Avars and Slavs. In 809, Serdica was incorporated into the Bulgarian Empire by Khan Krum and became known as Sredets. In 1018, the Byzantines ended Bulgarian rule ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
