What connections do the changes and continuities for pastoralists have with the rise of Islam?

"Travel and trade also flourished in this period [...] One 9th-century writer tells us of [multi-lingual] Iraqi Jews who criss-crossed Eurasia, travelling between France and China (covering Muslim lands, southern Russia, and India along the way), and the discovery of thousands of Abbasid coins in Scandinavia attests to the scope of this commercial activity. Even the spread of papermaking from China to the Near East is instructive in this context: our sources tell us that Muslims defeated a Chinese army in 751, capturing papermakers in the process from whom they learned the techniques themselves. What is interesting is that such hostile circumstances – a bloody battle in Central Asia – did little to hinder cross-cultural interaction and the spread of commodities, people, and ideas."
