Question: Who was the mother of the person under whom the foreign group that conquered the country where Grenfell and Hunt sent things to in AD 43 reached its greatest extent?

<P0-S0> in 1882, egypt, while still nominally part of the ottoman empire, came under effective british rule, and british archaeologists began the systematic exploration of the country. <P0-S1> because oxyrhynchus was not considered an ancient egyptian site of any importance, it was neglected until 1896, when two young excavators, bernard pyne grenfell and arthur surridge hunt, both fellows of the queen's college, oxford, began to excavate it. <P0-S2> "my first impressions on examining the site were not very favourable," wrote grenfell. <P0-S3> "the rubbish mounds were nothing but rubbish mounds." <P0-S4> however, they very soon realized what they had found. <P0-S5> the unique combination of climate and circumstance had left at oxyrhynchus an unequalled archive of the ancient world. <P0-S6> "the flow of papyri soon became a torrent," grenfell recalled. <P0-S7> "merely turning up the soil with one's boot would frequently disclose a layer. <P0-S8> "being classically educated englishmen, grenfell and hunt were mainly interested in the possibility that oxyrhynchus might reveal the lost masterpieces of classical greek literature. <P0-S9> they knew, for example, that the constitution of athens by aristotle had been discovered on egyptian papyrus in 1890. this hope inspired them and their successors to sift through the mountains of rubbish at oxyrhynchus for the next century. <P0-S10> their efforts were amply rewarded: it has been estimated that over 70% of all the literary papyri so far discovered come from oxyrhynchus, both copies of well-known standard works (many in versions significantly closer to the originals than those that had been transmitted in medieval manuscripts) and previously unknown works by the greatest authors of antiquity. <SEP> <P1-S0> 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. <P1-S1> 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). <P1-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. <P1-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. <SEP> <P2-S0> However, from the many thousands of papyri excavated from Oxyrhynchus, only about 10% were literary. <P2-S1> The rest consisted of public and private documents: codes, edicts, registers, official correspondence, census-returns, tax-assessments, petitions, court-records, sales, leases, wills, bills, accounts, inventories, horoscopes, and private letters. <P2-S2> Still, Grenfell and Hunt found enough texts of more general interest to keep them going in the hope of finding more. <P2-S3> In their first year of digging alone, they found parts of several lost plays of Sophocles, such as the Ichneutae and many other books and fragments, including parts of what appeared to be an unknown Christian gospel. <P2-S4> These discoveries captured the public imagination, and Grenfell and Hunt sent articles and photos to newspapers in Britain, arguing the importance of their work and seeking donations to keep it going. <SEP> <P3-S0> The imperial period of Rome lasted approximately 1,500 years compared to the 500 years of the Republican era. <P3-S1> The empire reached its greatest extent under Trajan, the second in this line. <P3-S2> 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 ''. <P3-S3> Following Octavian's victory, the size of the empire was dramatically increased. <P3-S4> After the assassination of Caligula in AD 41, the Senate briefly considered restoring the republic, but the Praetorian Guard proclaimed Claudius emperor instead. <P3-S5> Under Claudius, the empire invaded Britannia, its first major expansion since Augustus. <P3-S6> 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. <P3-S7> 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. <P3-S8> His short reign was followed by the long reign of his brother Domitian, who was eventually assassinated. <P3-S9> The Senate then appointed the first of the Five Good Emperors. <SEP> <P4-S0> Hiberni (Ireland), Pictish (northern Britain) and Britons (southern Britain) tribes, all speaking Insular Celtic, inhabited the islands at the beginning of the 1st millennium AD. <P4-S1> The first Anglo-Saxons arrived as Roman power waned in the 5th century and eventually dominated the bulk of what is now England. <P4-S2> Viking invasions began in the 9th century, followed by more permanent settlements and political change—particularly in England. <P4-S3> The subsequent Norman conquest of England in 1066 and the later Angevin partial conquest of Ireland from 1169 led to the imposition of a new Norman ruling elite across much of Britain and parts of Ireland. <P4-S4> By the Late Middle Ages, Great Britain was separated into the Kingdoms of England and Scotland, while control in Ireland fluxed between Gaelic kingdoms, Hiberno-Norman lords and the English-dominated Lordship of Ireland, soon restricted only to The Pale. <P4-S5> Much of Brittonic-controlled Britain was conquered by the Roman Empire from AD 43. <P4-S6> The 1603 Union of the Crowns, Acts of Union 1707 and Acts of Union 1800 attempted to consolidate Britain and Ireland into a single political unit, the United Kingdom of Great Britain and Ireland, with the Isle of Man and the Channel Islands remaining as Crown Dependencies. <P4-S7> The expansion of the British Empire and migrations following the Irish Famine and Highland Clearances resulted in the distribution of the islands' population and culture throughout the world and a rapid de-population of Ireland in the second half of the 19th century. <P4-S8> Most of Ireland seceded from the United Kingdom after the Irish War of Independence and the subsequent Anglo-Irish Treaty (1919–1922), with six counties remaining in the UK as Northern Ireland. <SEP> <P5-S0> archaeological finds suggest that the area has been inhabited since the stone age. <P5-S1> following the roman invasion of britain in ad 43 and the conquering of the local britons in 70 ad the fortress settlement of clausentum was established. <P5-S2> it was an important trading port and defensive outpost of winchester, at the site of modern bitterne manor. <P5-S3> clausentum was defended by a wall and two ditches and is thought to have contained a bath house. <P5-S4> clausentum was not abandoned until around 410.
