<P0-S0> Charlemagne (/ ˈʃɑːrləmeɪn /) or Charles the Great (2 April 742 -- 28 January 814), numbered Charles I, was King of the Franks from 768, King of the Lombards from 774, and Holy Roman Emperor from 800. <P0-S1> He united much of western and central Europe during the early Middle Ages. <P0-S2> He was the first recognized emperor to rule from western Europe since the fall of the Western Roman Empire three centuries earlier. <P0-S3> The expanded Frankish state that Charlemagne founded is called the Carolingian Empire. <P0-S4> He was later invalidly canonized by the antipope Paschal III. <SEP> <P1-S0> Charlemagne's court in Aachen was the centre of the cultural revival sometimes referred to as the "Carolingian Renaissance". <P1-S1> Literacy increased, as did development in the arts, architecture and jurisprudence, as well as liturgical and scriptural studies. <P1-S2> The English monk Alcuin (d. 804) was invited to Aachen and brought the education available in the monasteries of Northumbria. <P1-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. <P1-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. <P1-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. <P1-S6> New works on religious topics and schoolbooks were also produced. <P1-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. <P1-S8> By the reign of Charlemagne, the language had so diverged from the classical that it was later called Medieval Latin. <SEP> <P2-S0> Sylvester is a name derived from the Latin adjective silvestris meaning ``wooded ''or`` wild'', which derives from the noun silva meaning ``woodland ''. <P2-S1> Classical Latin spells this with i. <P2-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. <P2-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. <SEP> <P3-S0> in 768 pepin's son charlemagne became king of the franks and began an extensive expansion of the realm. <P3-S1> he eventually incorporated the territories of present - day france, germany, northern italy, and beyond, linking the frankish kingdom with papal lands. <P3-S2> on christmas day of 800, pope leo iii crowned charlemagne emperor, restoring the title in the west for the first time in over three centuries. <SEP> <P4-S0> classical india refers to the period when much of the indian subcontinent was reunited under the gupta empire (c. 320–550 ce). <P4-S1> this period has been called the golden age of india and was marked by extensive achievements in science, technology, engineering, art, dialectic, literature, logic, mathematics, astronomy, religion, and philosophy that crystallized the elements of what is generally known as hindu culture. <P4-S2> the hindu-arabic numerals, a positional numeral system, originated in india and was later transmitted to the west through the arabs. <P4-S3> early hindu numerals had only nine symbols, until 600 to 800 ce, when a symbol for zero was developed for the numeral system. <P4-S4> the peace and prosperity created under leadership of guptas enabled the pursuit of scientific and artistic endeavors in india.
