Baha'u'llah arrived in Baghdad on 8 April 1853. The journey
from Tehran had been very difficult and had lasted three months. After a few
days in Baghdad, Baha'u'llah moved to Kazimayn, a Shi'i shrine city which at
that time was some five kilometers north-west of Baghdad (it has since become
incorporated into the city). The Iranian consul suggested to Him that since
Kazimayn tended to be full of rather fanatical elements, it would be safer for
Baha'u'llah if He lived in Baghdad itself in the mainly Persian-speaking
quarters on the west bank of the Tigris river. Baha'u'llah consented to this
and rented a house there.
