In the making of Islam and its laws, a learned community of jurists, authors, teachers and ordinary people intertwined their contributions across geographical and chronological borders. By contesting or undercutting political entities, they asserted the centrality of divine law in the socio-religious lives of humans and advanced the ways in which the law was perceived, practised and discussed. From the formative stages on, texts stood at the forefront of the progress of discussions. For the Shāfiʿī school, diverse transregional stimuluses helped it to survive and spread and occasionally to decay and contract between the ninth and the twentieth centuries. This chapter analyses the pivotal historical elements that enabled the expansion of the Shāfiʿī school, and Islamic law at large, in the Indian Ocean and Mediterranean littorals with a focus on individual, collective and institutional circulations from circles of learning. The emphasis here is on the people who participated in and contributed to the circulatory regime from its formative lands to its eventual movements in the oceanic rims, while the next chapter focuses on the texts as such.
