An influx of interstate and overseas migrants, particularly Irish, German and Chinese, saw the development of slums including a temporary "tent city" established on the southern banks of the Yarra. Chinese migrants founded the Melbourne Chinatown in 1851, which remains the longest continuous Chinese settlement in the Western World. In the aftermath of the Eureka Stockade, mass public support for the plight of the miners resulted in major political changes to the colony, including changes to working conditions across local industries including mining, agriculture and manufacturing.
