The
Roman fort ("Shsihmanova" or "Kaleto Fortress") is located on the western hill of Nikopol overlooking the town. It was initially built probably in the 1st c. AD as part of the
Limes Moesiae frontier defense system along the
Danube, part of the Danubian
limes. The garrison before 49 AD was
Ala I Scubulorum, a cavalry regiment. The Roman town grew up outside the fort. Two other Roman forts on the Danube were nearby to the west:
Securisca (3 km) and
Ansamus (5 km). A garrison of one of these was
ala Bosporanorum milliaria, a nominally 1000-strong cavalry regiment stationed there before the time of
Claudius (r. 41 to 54). Anasamus is included in the
Notitia Dignitatum with the garrison of the military unit
milites praeventores dating to 378 AD, and where there was also a
mansio included on the
Tabula Peutingeriana dating from the 3rd c. AD. These
milites praeventores are the only unit of this type recorded in the Notitia Dignitatum, and was a special regiment for active defense, including surprise actions, of the border sector. When the border and the Roman Empire in the Lower Danubian lands were strongly threatened by unceasing
Hunnic raids in 447, the inhabitants of Ansamus showed unexpected high spirit and enviable military skills, by which they not only repelled an enemy siege, but demanded conditions from
Attila himself, according to
Priscus. "They did not defend themselves from their walls, but fought battles outside the walls against countless troops and famous Scythian generals. Because of this, the Huns despaired and retreated from the town. The inhabitants of the town made raids far from their fortifications when their scouts informed them that enemies were passing, laden with Roman booty. They attacked them unexpectedly and took their booty. Although they were far fewer than the enemy, they exceeded them in courage and strength." After the decline of the
Roman Empire, the town turned out to be located at the northern border of the
Byzantine Empire. In 1059, it was named
Nicopolis,
Greek for "City of Victory". During most of the Middle Ages, it was part of the
Bulgarian Empire from its foundation in 681. After the
fall of Tarnovo in 1393, the last Bulgarian Tsar
Ivan Shishman defended what remained of the Empire from the fortress of Nikopol, where he was captured after the town was conquered by the Ottomans in 1395. Nikopol is therefore sometimes considered the capital of Bulgaria during these two years. It was the site of the
Battle of Nicopolis, the last large-scale
crusade of the Middle Ages, in 1396. At the fortress of Nicopolis, the united armies of Christian Europe headed by
Hungarian king
Sigismund and various
French knights were defeated by the Ottomans under
Bayezid I and his
Serbian vassal
Stefan Lazarević. Under
Ottoman rule, Nikopol developed into an important military and administrative centre as a
sanjak, with a strong fortress and a flourishing economic, spiritual and political life, until it went into decline during the 17th and 18th centuries. It was the centre of a district (
kaza), but it was overtaken by
Pleven as the regional centre of that part of the Bulgarian lands. Nikopol was captured by the Russians in the
Battle of Nikopol in 1877. ==Modern times==
