During the late nineteenth century, Mumbai’s encounter with the industrial revolution resulted in the emergence of a kind of habitat that was unfit for humans as it was devoid of civic services like water and drainage and termed a ‘slum’. This was following a somewhat similar trajectory to the industrial centres of England like Liverpool and Manchester. It was only after the outbreak of the bubonic plague in 1896 in Bombay that the colonial rulers were forced to acknowledge the question of housing and sanitary conditions. In a response to the plague, the Bombay Improvement Trust (BIT) was set up in 1898 and the Bombay Development Department (BDD) in 1920 to construct low-cost housing for the innumerable workers that were working at the mills, the ports and involved in constructing the railways. Now we know that it was too late an intervention and created a legacy of housing backlog and shortage that continues till date. Historians lament the fact that both BIT and BDD aggravated the housing crisis as through their interventions they dis-housed more people than they provided housing to.
