<P0-S0> one key figure in the plans for what would come to be known as american empire, was a geographer named isiah bowman. <P0-S1> bowman was the director of the american geographical society in 1914. three years later in 1917, he was appointed to then president woodrow wilson's inquiry in 1917. the inquiry was the idea of president wilson and the american delegation from the paris peace conference. <P0-S2> the point of this inquiry was to build a premise that would allow for u.s authorship of a 'new world' which was to be characterized by geographical order. <P0-S3> as a result of his role in the inquiry, isiah bowman would come to be known as wilson's geographer. <SEP> <P1-S0> Rotrude (or sometimes referred to as Hruodrud/Hruodhaid) (775/778 – 6 June 810) was a Frankish princess, the second daughter of Charlemagne from his marriage to Hildegard. <SEP> <P2-S0> Charlemagne's court in Aachen was the centre of the cultural revival sometimes referred to as the "Carolingian Renaissance". <P2-S1> Literacy increased, as did development in the arts, architecture and jurisprudence, as well as liturgical and scriptural studies. <P2-S2> The English monk Alcuin (d. 804) was invited to Aachen and brought the education available in the monasteries of Northumbria. <P2-S3> Charlemagne's chancery—or writing office—made use of a new script today known as Carolingian minuscule,[M] allowing a common writing style that advanced communication across much of Europe. <P2-S4> Charlemagne sponsored changes in church liturgy, imposing the Roman form of church service on his domains, as well as the Gregorian chant in liturgical music for the churches. <P2-S5> An important activity for scholars during this period was the copying, correcting, and dissemination of basic works on religious and secular topics, with the aim of encouraging learning. <P2-S6> New works on religious topics and schoolbooks were also produced. <P2-S7> Grammarians of the period modified the Latin language, changing it from the Classical Latin of the Roman Empire into a more flexible form to fit the needs of the church and government. <P2-S8> By the reign of Charlemagne, the language had so diverged from the classical that it was later called Medieval Latin. <SEP> <P3-S0> it is not known where or when li kening was born, but it is known that he was li keyong's youngest brother and therefore would have been born after 856, when li keyong was born. <P3-S1> their father was the ethnic shatuo general li guochang, whose name was originally zhuye chixin but was later bestowed the tang dynasty imperial clan name of li and a new name of guochang, but because li kening's birth year is unknown, it is not known whether he would have been born with the name of li or zhuye. <P3-S2> he was said to be kind and filially pious, and (despite his eventual fate) described to be the most virtuous among li keyong's brothers and cousins. <SEP> <P4-S0> Sylvester is a name derived from the Latin adjective silvestris meaning ``wooded ''or`` wild'', which derives from the noun silva meaning ``woodland ''. <P4-S1> Classical Latin spells this with i. <P4-S2> In Classical Latin y represented a separate sound distinct from i, not a native Latin sound but one used in transcriptions of foreign words. <P4-S3> After the Classical period y came to be pronounced as i. Spellings with Sylv - in place of Silv - date from after the Classical period.
