In 1841, a smallpox epidemic broke out in the Bur Dubai locality, forcing residents to relocate east to Deira. In 1896, fire broke out in Dubai, a disastrous occurrence in a town where many family homes were still constructed from "barasti" – palm fronds. The conflagration consumed half the houses of Bur Dubai, while the district of Deira was said to have been totally destroyed. The following year, more fires broke out. A female slave was caught in the act of starting one such blaze and was subsequently put to death.
