Debates on state formation and Arab contacts

How did early medieval states form, and how did contact with the Arab world change India? Historians debate whether states were built by land grants, by conquest, by integrating tribes, or by all three together. A concrete example is Sind: after the Arab conquest in the early eighth century, trade, coinage and translation continued across the frontier, and Sind became a bridge between India and West Asia. This chapter separates the main models and tests them against evidence from different regions.
