At least 18 people lived in one tenement apartment. There were only two toilets stalled on each floor and one bathtub in the kitchen of the apartment. Jacob Riis did a lot of research and reporting of the conditions that immigrants faced such as work issues and living conditions.

Meanwhile, alerted to the impending crisis, Russia—Serbia’s own mighty supporter in the Balkans—began its own initial steps towards military mobilization against Austria.
