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.
