The last traces of Mansur’s Round City were demolished in the early 1870s when Midhat Pasha, the reformist Ottoman governor, tore down the venerable city walls in a fit of modernising zeal. Baghdadis have since grown used to being excluded from the centre of their resilient capital. Just as they had been barred from the inner sanctum of the city under Mansur, so were their 20th-century counterparts excluded from the heart of Baghdad on pain of death 12 centuries later. The heavily guarded district of Karadat Maryam, slightly south of the original Round City on the west bank, became the regime headquarters, the engine room of a giant machine carefully calibrated to cow, control and using the multiple security organisations that enabled a country to devour itself.
Under the American occupation of 2003 it became the even more intensely fortified Green Zone, a surreal dystopia of six square miles in which Iraqis were largely unwelcome in their own capital. Today, after a 12-year interlude, the Green Zone is open to Baghdadis again. But as so often in their extraordinarily bloody history, Iraqis find they have very little to cheer about as the country tears itself apart. The great city of Baghdad survives, but its people are once again engulfed in terrible violence.
