unknown vivica a. fox. <P0-S4> the song was also included on the mca records motion picture soundtrack for 1985's secret admirer. <P0-S5> billboard named the song # 85 on their list of 100 greatest girl group songs of all time. <SEP> <P1-S0> The imperial period of Rome lasted approximately 1,500 years compared to the 500 years of the Republican era. <P1-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 ''. <P1-S2> Following Octavian's victory, the size of the empire was dramatically increased. <P1-S3> After the assassination of Caligula in AD 41, the Senate briefly considered restoring the republic, but the Praetorian Guard proclaimed Claudius emperor instead. <P1-S4> Under Claudius, the empire invaded Britannia, its first major expansion since Augustus. <P1-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. <P1-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. <P1-S7> His short reign was followed by the long reign of his brother Domitian, who was eventually assassinated. <P1-S8> The Senate then appointed the first of the Five Good Emperors. <P1-S9> The empire reached its greatest extent under Trajan, the second in this line. <SEP> <P2-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). <P2-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. <P2-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. <P2-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> <P3-S0> iran is home to one of the world's oldest civilizations, beginning with the formation of the proto-elamite and elamite kingdoms in 3200–2800 bc. <P3-S1> the iranian medes unified the area into the first of many empires in 625 bc, after which it became the dominant cultural and political power in the region. <P3-S2> iran reached the pinnacle of its power during the achaemenid empire founded by cyrus the great in 550 bc, which at its greatest extent comprised major portions of the ancient world, stretching from parts of the balkans (thrace-macedonia, bulgaria-paeonia) and eastern europe proper in the west, to the indus valley in the east, making it the largest empire the world had yet seen. <P3-S3> the empire collapsed in 330 bc following the conquests of alexander the great. <P3-S4> the parthian empire emerged from the ashes and was succeeded by the sassanid dynasty in 224 ad, under which iran again became one of the leading powers in the world, along with the roman-byzantine empire, for a period of more than four centuries. <SEP> <P4-S0> The earliest recorded incidents of collective civil disobedience took place during the Roman Empire[citation needed]. <P4-S1> Unarmed Jews gathered in the streets to prevent the installation of pagan images in the Temple in Jerusalem. <P4-S2> [citation needed][original research?] <P4-S3> In modern times, some activists who commit civil disobedience as a group collectively refuse to sign bail until certain demands are met, such as favorable bail conditions, or the release of all the activists. <P4-S4> This is a form of jail solidarity. <P4-S5> [page needed] There have also been many instances of solitary civil disobedience, such as that committed by Thoreau, but these sometimes go unnoticed. <P4-S6> Thoreau, at the time of his arrest, was not yet a well-known author, and his arrest was not covered in any newspapers in the days, weeks and months after it happened. <P4-S7> The tax collector who arrested him rose to higher political office, and Thoreau's essay was not published until after the end of the Mexican War.
