Domitian's Dacian War in the context of "First century"

The 1st century was the century spanning AD 1 (represented by the Roman numeral I) through AD 100 (C) according to the Julian calendar. It is often written as the 1st century AD or 1st century CE to distinguish it from the 1st century BC (or BCE) which preceded it. The 1st century is considered part of the Classical era, epoch, or historical period. The Roman Empire, Han China and the Parthian Persia were the most powerful and hegemonic states.

During this century, the Roman Empire (ruled by the Julio-Claudian and Flavian dynasties) continued to be in a period of relative stability known as Pax Romana, withstanding a financial crisis in 33 and a civil war in 69. In Europe, Rome expanded into Britain and fought wars in Germania and Dacia. In Africa, Rome was challenged by Tacfarinas, who led his own Musulamii tribe and a loose and changing coalition of other Berber tribes before being defeated in 24. In West Asia, Rome defeated a Jewish rebellion (66–73) and fought a war with Parthia from 58–63, though the latter conflict was inconclusive. In East Asia, the Chinese Western Han dynasty was overthrown and replaced by the Xin dynasty in 9, which in turn faced its own rebel movements (namely the Red Eyebrows and Lulin), and was replaced by the Eastern Han dynasty in 25. The Eastern Han dynasty then faced and quelled a rebellion by the Trưng sisters (40–43). In 58, the Eastern Han dynasty entered a golden age with the Rule of Ming and Zhang, who were generally regarded as able administrators who cared about the common welfare of the people and who promoted officials with integrity. On its northern frontier, the Chinese dynasties waged intermittent war with the Xiongnu before emerging victorious in 91. The states of Funan and Xianbei were also established in this century.

Trajan's First Dacian War took place from 101 to 102.

The Kingdom of Dacia, under King Decebalus, had become a threat to the Roman Empire, and defeated several of Rome's armies during Domitian's reign (81–96). Despite the peace treaty established after Domitian's Dacian War, Trajan was set on ridding their new threat to Rome's power and in 101 set out determined to defeat Dacia. After a year of heavy fighting, King Decebalus came to terms and accepted peace.

The Third Battle of Tapae (101) was the decisive battle of the first of Trajan's Dacian Wars, in which the Roman Emperor defeated the Dacian King Decebalus's army. Other setbacks in the campaign delayed its completion until 102. The battle is most likely the battle-scene depicted on Plate 22 of Trajan's column.

It followed the earlier battles at the same place during Domitian's Dacian War.

Viminacium (also Viminatium) was a major city, military camp, and the capital of the Roman province of Moesia (modern Serbia). Following the division of Moesia in 87, following Domitian's Dacian War, it became the capital of Moesia Superior. As of 2018, only 3-4% of the site has been explored.

The site is located 6 km (3.7 mi) from the modern town of Kostolac in Eastern Serbia. The city dates back to the 1st century AD, and at its peak it is believed to have had 40,000 inhabitants, making it one of the biggest cities in the Balkans of that time. It lies on the Roman road Via Militaris. Viminacium was devastated by Huns in the 5th century, but was later rebuilt by Justinian. It was completely destroyed with the arrival of Slavs in the 6th century. Today, the archaeological site occupies a total of 450 hectares (1,100 acres), and contains remains of temples, streets, squares, amphitheatres, palaces, hippodromes and Roman baths.

Diana Fort (Serbian: Тврђава Диана, romanized: Tvrđava Diana) is a Roman fort located near the hamlet of Karataš, 8 km northwest of Kladovo, in eastern Serbia in the Karataš archaeological site. It is located on cliffs of the Đerdap, above the Danube, on a strategic location overlooking the Danube frontier. It has been extensively excavated, is one of the best explored forts of the Moesian Limes, and can be visited today.

It was built in the Tiberian-Claudian age as part of the Roman Moesian Limes frontier system of linked forts along the Danube. After its destruction during Domitian's Dacian War, it was rebuilt in 100 AD during preparation for Trajan's Dacian Wars with a larger area of 1.7 ha (compared to the earlier 1.04 ha) and with the main buildings in stone. It then became also known as Statio Cataractarum Dianae (Diana Cataracts Station) as it protected the entrance to the canal dug in preparation for the wars to avoid cataracts in the main river course. The canal was more than 3 km long and 40 m wide, an achievement celebrated on the Imperial Tablet found near the fort.
