Trajan was Roman emperor from 98 to 117 AD, the second of the Five Good Emperors of the Nerva–Antonine dynasty. He was a philanthropic ruler and a successful soldier-emperor who led the Roman Empire to its greatest territorial extent by the time of his death. He was given the title of optimus by the Roman Senate.
The 100s was a decade that ran from January 1, AD 100, to December 31, AD 109.
Moesia was an ancient region and later Roman province situated in the Balkans south of the Danube River. Moesian Province was first administered by governor of Noricum as 'Civitates of Moesia and Triballia'. It included most of the territory of modern eastern Serbia, Kosovo, north-eastern Albania, northern parts of North Macedonia, Northern Bulgaria, Romanian Dobruja and small parts of Southern Ukraine.
Sarmizegetusa Regia was the capital and the most important military, religious and political centre of the Dacians before the wars with the Roman Empire. Erected on top of a 1200 m high mountain, the fortress, comprising six citadels, was the core of a strategic defensive system in the Orăștie Mountains.
Legio II Traiana, was a legion of the Imperial Roman army raised by emperor Trajan, along with XXX Ulpia Victrix, for the campaigns in Dacia. Records of the II Traiana Fortis have been recovered from Egypt dating to the middle of the 5th century. The legion's emblem was the demi-god Hercules.
The Dacian Wars were two military campaigns fought between the Roman Empire and Dacia during Emperor Trajan's rule. The conflicts were triggered by the constant Dacian threat on the Danubian province of Moesia and also by the increasing need for resources of the economy of the Empire.
Lucius Licinius Sura was an influential Roman Senator from Tarraco, Hispania, a close friend of the Emperor Trajan and three times consul, in a period when three consulates were very rare for non-members of the Imperial family. The dates of two of these consulates are certain: in 102 and 107 AD he was consul ordinarius; the date of his first consulate, as a suffect consul has been debated. Fausto Zevi postulated that he was also suffect consul in 97, based on a plausible restoration of part of the Fasti Ostienses, which reads "..]us". However, two more recently recovered fragments of military diplomas show that the name of this consul is L. Pomponius Maternus, who is otherwise unknown. Most authorities have returned to endorsing C.P. Jones' surmise that Sura was consul for the first time in the year 93. He was a correspondent of Pliny the Younger.
The Second Battle of Tapae (101) was the decisive battle of the first Dacian War, in which Roman Emperor Trajan 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.
Colonia Ulpia Traiana Augusta Dacica Sarmizegetusa was the capital and the largest city of Roman Dacia, later named Ulpia Traiana Sarmizegetusa after the former Dacian capital, located some 30 km away. Possibly built on the ground of a camp of the Fifth Macedonian Legion, the city was settled by veterans and colonists from Italian peninsula. From the very beginning it received the title of colonia and the status of ius Italicum. The urban centre and the civil settlement occupied an area of over 130 hectares, with a population reaching between 20,000 and 25,000 at the end of the 2nd century beginning of the 3rd. The centre built in a Hippodamian Plan was surrounded by strong fortifications over 32.4 hectares.
The Battle of Sarmizegetusa was a siege of Sarmizegetusa, the capital of Dacia, fought in 106 between the army of the Roman Emperor Trajan, and the Dacians led by King Decebalus.
Roman Dacia was a province of the Roman Empire from 106 to 271–275 AD. Its territory consisted of what are now the regions of Oltenia, Transylvania and Banat. During Roman rule, it was organized as an imperial province on the borders of the empire. It is estimated that the population of Roman Dacia ranged from 650,000 to 1,200,000. It was conquered by Trajan (98–117) after two campaigns that devastated the Dacian Kingdom of Decebalus. However, the Romans did not occupy its entirety; Crișana, Maramureș, and most of Moldavia remained under the Free Dacians.
This section of the timeline of Romanian history concerns events from Late Neolithic until Late Antiquity, which took place in or are directly related with the territory of modern Romania.
Marcus Cornelius Nigrinus Curiatius Maternus was a Roman senator and general during the reign of Domitian. He was suffect consul during the nundinium of September to October AD 83 with Lucius Calventius Sextius Carminius Vetus. Although some experts consider him a rival with Trajan as heir apparent to the emperor Nerva, he is primarily known from inscriptions.
Quintus Glitius Atilius Agricola was a Roman senator and general who held several posts in the emperor's service. He was twice suffect consul: for the first time in AD 97 with Lucius Pomponius Sura as his colleague, and the second time in 103 when he replaced the emperor Trajan. He is the last known person to have held two suffect consulates. Agricola is known only through a large number of fragmentary inscriptions from Augusta Taurinorum, which appears to be his home town.
Gaius Cilnius Proculus was a Roman senator active during the reign of Domitian. He was suffect consul for the nundinium September–December AD 87 with Lucius Neratius Priscus as his colleague. It is unknown how or if Proculus is related to the better-known Gaius Cilnius Maecenas. Proculus is known only through surviving inscriptions.
Lucius Annius Fabianus was a Roman senator and general. He was suffect consul for the nundinium of November–December AD 141; his colleague is not known.
Titus Julius Maximus Manlianus was a Roman senator active in the early second century who held a number of offices in the emperor's service. He was suffect consul for the nundinium July to September 112 as the colleague of Publius Stertinius Quartus. His complete name was Titus Julius Maximus Manlianus Brocchus Servilianus Aulus Quadronius [Verus?] Lucius Servilius Vatia Cassius Cam[ars].
Decimus Terentius Gentianus was a Roman senator of the 2nd century AD who held a number of offices in the imperial service, as well as gentianus with Lucius Co[...] as his colleague. His origins may be in Gallia Narbonensis, and Gentianus may have been the son of Decimus Terentius Scaurianus, one of Trajan's generals.
Lucius Cossonius Gallus was a Roman senator, who held a number of offices in the imperial service. He was suffect consul in one of the nundinia that fell in the last half of AD 117 as the colleague of Publius Afranius Flavianus. His full name is Lucius Cossonius Gallus Vecillius Crispinus Mansuanius Marcellinus Numisius Sabinus. He is known entirely from inscriptions.
The history of Dacia comprises the events surrounding the historical region roughly corresponding to the present territory of Romania and Moldova and inhabited by the Getae and Dacian peoples, with its capital Sarmizegetusa Regia.
