It can come as a surprise that the largest Muslim (or perhaps more accurately, Muslim-majority) country is Indonesia, far from the religion’s origins in the Middle East. It is—probably as a result—not always included, or at least not centrally, in discourse about Islam. James M Dorsey, on the other hand, puts the country front and center in his new book The Battle for the Soul of Islam.

The Hijaz, that part of the Arabian Peninsula which contains the holy cities of Mecca and Medina, was long subject to imperialism, but not of Western variety: it was instead subject to the Ottomans. Although nominally under Ottoman suzerainty for centuries, it was ironically 19th-century British imperialism that forced Istanbul to attempt to consolidate its control over the region.
