Question: Who was the mother of the person under whom the empire that colonized Nasser's country in the 1st century BC reached its greatest extent?

<P0-S0> The imperial period of Rome lasted approximately 1,500 years compared to the 500 years of the Republican era. <P0-S1> The first two centuries of the empire's existence were a period of unprecedented political stability and prosperity known as the Pax Romana, or ``Roman Peace ''. <P0-S2> Following Octavian's victory, the size of the empire was dramatically increased. <P0-S3> After the assassination of Caligula in AD 41, the Senate briefly considered restoring the republic, but the Praetorian Guard proclaimed Claudius emperor instead. <P0-S4> Under Claudius, the empire invaded Britannia, its first major expansion since Augustus. <P0-S5> After Claudius' successor, Nero, committed suicide in AD 68, the empire suffered a series of brief civil wars, as well as a concurrent major rebellion in Judea, during which four different legionary generals were proclaimed emperor. <P0-S6> Vespasian emerged triumphant in AD 69, establishing the Flavian dynasty, before being succeeded by his son Titus, who opened the Colosseum shortly after the eruption of Mount Vesuvius. <P0-S7> His short reign was followed by the long reign of his brother Domitian, who was eventually assassinated. <P0-S8> The Senate then appointed the first of the Five Good Emperors. <P0-S9> The empire reached its greatest extent under Trajan, the second in this line. <SEP> <P1-S0> the maurya empire (322–185 bce) was the first empire to unify india into one state, and was the largest on the indian subcontinent. <P1-S1> at its greatest extent, the mauryan empire stretched to the north up to the natural boundaries of the himalayas and to the east into what is now assam. <P1-S2> to the west, it reached beyond modern pakistan, to the hindu kush mountains in what is now afghanistan. <P1-S3> the empire was established by chandragupta maurya in magadha (in modern bihar) when he overthrew the nanda dynasty. <P1-S4> chandragupta's son bindusara succeeded to the throne around 297 bc. <P1-S5> by the time he died in c. 272 bc, a large part of the subcontinent was under mauryan suzerainty. <P1-S6> however, the region of kalinga (around modern day odisha) remained outside mauryan control, perhaps interfering with their trade with the south. <SEP> <P2-S0> the roman empire reached its greatest territorial extent during the 2nd century ad; the following two centuries witnessed the slow decline of roman control over its outlying territories. <P2-S1> economic issues, including inflation, and external pressure on the frontiers combined to make the 3rd century politically unstable, with emperors coming to the throne only to be rapidly replaced by new usurpers. <P2-S2> military expenses increased steadily during the 3rd century, mainly in response to the war with sassanid persia, which revived in the middle of the 3rd century. <P2-S3> the army doubled in size, and cavalry and smaller units replaced the legion as the main tactical unit. <P2-S4> the need for revenue led to increased taxes and a decline in numbers of the curial, or landowning, class, and decreasing numbers of them willing to shoulder the burdens of holding office in their native towns. <P2-S5> more bureaucrats were needed in the central administration to deal with the needs of the army, which led to complaints from civilians that there were more tax-collectors in the empire than tax-payers. <SEP> <P3-S0> Under Tito's leadership, Yugoslavia became a founding member of the Non-Aligned Movement. <P3-S1> In 1961, Tito co-founded the movement with Egypt's Gamal Abdel Nasser, India's Jawaharlal Nehru, Indonesia's Sukarno and Ghana's Kwame Nkrumah, in an action called The Initiative of Five (Tito, Nehru, Nasser, Sukarno, Nkrumah), thus establishing strong ties with third world countries. <P3-S2> This move did much to improve Yugoslavia's diplomatic position. <P3-S3> On 1 September 1961, Josip Broz Tito became the first Secretary-General of the Non-Aligned Movement. <SEP> <P4-S0> In 332 BC, Macedonian ruler Alexander the Great conquered Egypt as he toppled the Achaemenids and established the Hellenistic Ptolemaic Kingdom, whose first ruler was one of Alexander's former generals, Ptolemy I Soter. <P4-S1> The Ptolemies had to fight native rebellions and were involved in foreign and civil wars that led to the decline of the kingdom and its final annexation by Rome. <P4-S2> The death of Cleopatra ended the nominal independence of Egypt resulting in Egypt becoming one of the provinces of the Roman Empire. <SEP> <P5-S0> Marcus Ulpius Traianus was born on 18 September 53AD in the Roman province of Hispania Baetica (in what is now Andalusia in modern Spain), in the city of Italica (now in the municipal area of Santiponce, in the outskirts of Seville). <P5-S1> Although frequently designated the first provincial emperor, and dismissed by later writers such as Cassius Dio (himself of provincial origin) as "an Iberian, and neither an Italian nor even an Italiot", Trajan appears to have hailed on his father's side from the area of Tuder (modern Todi) in Umbria, at the border with Etruria, and on his mother's side from the Gens Marcia, of an Italic family of Sabine origin. <P5-S2> Trajan's birthplace of Italica was founded as a Roman military colony of "Italian" settlers in 206BC, though it is unknown when the Ulpii arrived there. <P5-S3> It is possible, but cannot be substantiated, that Trajan's ancestors married local women and lost their citizenship at some point, but they certainly recovered their status when the city became a municipium with Latin citizenship in the mid-1st century BC.
