paragraph_text: The imperial period of Rome lasted approximately 1,500 years compared to the 500 years of the Republican era. 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 ''. Following Octavian's victory, the size of the empire was dramatically increased. After the assassination of Caligula in AD 41, the Senate briefly considered restoring the republic, but the Praetorian Guard proclaimed Claudius emperor instead. Under Claudius, the empire invaded Britannia, its first major expansion since Augustus. 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. 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. His short reign was followed by the long reign of his brother Domitian, who was eventually assassinated. The Senate then appointed the first of the Five Good Emperors. The empire reached its greatest extent under Trajan, the second in this line.

paragraph_text: Queen are one of the most bootlegged bands ever, according to Nick Weymouth, who manages the band's official website. A 2001 survey discovered the existence of 12,225 websites dedicated to Queen bootlegs, the highest number for any band. Bootleg recordings have contributed to the band's popularity in certain countries where Western music is censored, such as Iran. In a project called Queen: The Top 100 Bootlegs, many of these have been made officially available to download for a nominal fee from Queen's website, with profits going to the Mercury Phoenix Trust. Rolling Stone ranked Queen at number 52 on its list of the "100 Greatest Artists of All Time", while ranking Mercury the 18th greatest singer, and May the twenty-sixth greatest guitarist. Queen were named 13th on VH1's 100 Greatest Artists of Hard Rock list, and in 2010 were ranked 17th on VH1's 100 Greatest Artists of All Time list. In 2012, Gigwise readers named Queen the best band of past 60 years.

paragraph_text: 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). 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. 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. 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.

paragraph_text: Aelia Eudocia Augusta (; Late Greek: Αἰλία Εὐδοκία Αὐγούστα; 401 – 460 AD), also called Saint Eudocia, was a Greek Eastern Roman Empress by marriage to Byzantine emperor Theodosius II (r. 408–450), and a prominent historical figure in understanding the rise of Christianity. Eudocia lived in a world where Greek paganism and Christianity existed side-by-side with both pagans and non-orthodox Christians being persecuted. Although Eudocia's work has been mostly ignored by modern scholars, her poetry and literary work are great examples of how her Christian faith and Greek heritage were intertwined, exemplifying a legacy that the Roman Empire bequeathed on the Christian world.

paragraph_text: Swaziland derives its name from a later king named Mswati II. KaNgwane, named for Ngwane III, is an alternative name for Swaziland the surname of whose royal house remains Nkhosi Dlamini. Nkhosi literally means "king".

The Emakhandzambili clans were initially incorporated into the kingdom with wide autonomy, often including grants of special ritual and political status. The extent of their autonomy however was drastically curtailed by Mswati, who attacked and subdued some of them in the 1850s.

paragraph_text: The Rohingya people have consistently faced human rights abuses by the Burmese regime that has refused to acknowledge them as Burmese citizens (despite some of them having lived in Burma for over three generations)—the Rohingya have been denied Burmese citizenship since the enactment of a 1982 citizenship law. The law created three categories of citizenship: citizenship, associate citizenship, and naturalised citizenship. Citizenship is given to those who belong to one of the national races such as Kachin, Kayah (Karenni), Karen, Chin, Burman, Mon, Rakhine, Shan, Kaman, or Zerbadee. Associate citizenship is given to those who cannot prove their ancestors settled in Myanmar before 1823, but can prove they have one grandparent, or pre-1823 ancestor, who was a citizen of another country, as well as people who applied for citizenship in 1948 and qualified then by those laws. Naturalized citizenship is only given to those who have at least one parent with one of these types of Burmese citizenship or can provide "conclusive evidence" that their parents entered and resided in Burma prior to independence in 1948. The Burmese regime has attempted to forcibly expel Rohingya and bring in non-Rohingyas to replace them—this policy has resulted in the expulsion of approximately half of the 800,000 Rohingya from Burma, while the Rohingya people have been described as "among the world's least wanted" and "one of the world's most persecuted minorities." But the origin of ‘most persecuted minority’ statement is unclear.

paragraph_text: "Standing in the Shadows of Love" is a 1966 hit single recorded by the Four Tops for the Motown label. Written and produced by Motown's main production team Holland–Dozier–Holland, the song is one of the most well-known Motown tunes of the 1960s. A direct follow-up to the #1 hit "Reach Out I'll Be There" (even featuring a similar musical arrangement), "Standing in the Shadows of Love" reached #2 on the soul chart and #6 on the "Billboard" Hot 100 in 1967. It also reached #6 in the UK. Though the song was well-received, it has received some criticism. Author Martin Charles Strong notes that it rehashed the formula of "Reach Out I'll Be There" and achieved similar success by reaching the Top 10 in both the US and UK. It is ranked #470 on "Rolling Stone" 's list of The 500 Greatest Songs of All Time.
