Question: When did the first immigrants from the nation that the developer of the printing method that aided the growth of literacy, arrive in America?

<P0-S0> at the beginning of the caliphate or islamic empire, the reliance on courts initially confined sponsorship and scholarly activities to major centres. <P0-S1> within several centuries, the development of muslim educational institutions such as the madrasah and masjid eventually introduced such activities to provincial towns and dispersed them across the islamic legal schools and sufi orders. <P0-S2> in addition to religious subjects, they also taught the "rational sciences," as varied as mathematics, astronomy, astrology, geography, alchemy, philosophy, magic, and occultism, depending on the curriculum of the specific institution in question. <P0-S3> the madaris, however, were not centres of advanced scientific study; scientific advances in islam were usually carried out by scholars working under the patronage of royal courts. <P0-S4> during this time,[when?] <P0-S5> the caliphate experienced a growth in literacy, having the highest literacy rate of the middle ages, comparable to classical athens' literacy in antiquity but on a much larger scale. <P0-S6> the emergence of the maktab and madrasa institutions played a fundamental role in the relatively high literacy rates of the medieval islamic world. <SEP> <P1-S0> In the 1670s, the first significant groups of German immigrants arrived in the British colonies, settling primarily in Pennsylvania, New York, and Virginia. <P1-S1> None of the German states had American colonies. <P1-S2> Immigration continued in very large numbers during the 19th century, with eight million arrivals from Germany. <P1-S3> Between 1820 and 1870 over seven and a half million German immigrants came to the United States -- more than doubling the entire population of the country. <P1-S4> By 2010, their population grew to 49.8 million immigrants, reflecting a jump of 6 million people since 2000. <SEP> <P2-S0> san francisco taiko dojo, founded in 1968 by grand master seiichi tanaka, was the first taiko group in north america, and has been seen as the primary link between the japanese and north american branches of the art form. <P2-S1> additionally, tanaka's belief that learning to play taiko only requires a genuine interest in the art form (rather than japanese ethnicity or heritage), has greatly contributed to taiko's success and growth outside japan. <SEP> <P3-S0> The number of books published in the period of the Enlightenment increased dramatically due to the increase in demand for books, which resulted from the increased literacy rates and the declining cost and easier availability of books made possible by the printing press. <P3-S1> The explosion of the print culture, which started in the 15th century with Johannes Gutenberg's printing press, was both a result of and a cause of the increase in literacy. <P3-S2> There was a shift in the percentages of books printed in various categories during the 17th century. <SEP> <P4-S0> There are many statues of Gutenberg in Germany, including the famous one by Bertel Thorvaldsen (1837) at Gutenbergplatz in Mainz, home to the eponymous Johannes Gutenberg University of Mainz and the Gutenberg Museum on the history of early printing. <P4-S1> The latter publishes the "Gutenberg-Jahrbuch", the leading periodical in the field.
