Water management depends on both the physical and social structures of large cities. In Paris, these elements interacted to limit and constrain access to water for large segments of the population for long periods of time. The very unequal distribution of property in the city is central to understanding water regimes in Paris and their evolution over time. This article analyzes the evolution of water systems in Paris from the mid-nineteenth century to the mid-twentieth century, considering access to water (and its quality) as well as the provision of sewers to remove waste soiled materials. Important social variations in the modalities of access to water within the city persisted for a long time. They were a consequence of choices made in organizing the distribution of water in the city.

Each year, around 100,000 people acquire French nationality, most often based on their family situation (marriage, birth and childhood in France, being parents of French children, etc.). These acquisitions of nationality are also linked to historical and geopolitical transformations. Since the early 1960s, more than 200,000 individuals who lost their French nationality, in many cases when colonized territories became independent, have been reintegrated. The history of reintegration, a discreet and little-known procedure, sheds light on some of the ‘nationality trouble’ of the post-colonial era.

Paris came under siege twice between September 1870 and May 1871, first by the Prussian army and then by the Versailles government’s assault on the Commune. The first resulted in a severe famine; the second in a bloodbath. We investigate the impact of this crisis on child mortality, adult height, and adult mortality, using original vital records and military register data from one of the city’s lowest-income areas. Deaths more than doubled at all ages during this period, and under-5 mortality rates increased by 30% for children born in 1869 and 1870. Those conceived and gestated during the crisis ended up significantly shorter and faced 40% higher adult mortality than unaffected cohorts born afterwards, but children aged 2–5 later recovered in height as living conditions quickly improved. A nutritional shock’s translation into short-term variations in stature and into lifetime survival thus seems to depend not only on the shock’s duration but also on preceding and subsequent living conditions, which themselves interact with selection effects and critical age windows for physiological growth.

Following the Age of Revolution (Osterhammel, 2014), Paris witnessed two wars at the end of the 19th century. First, in September 1870, the Prussian army besieged the French capital, and then, beginning in March 1871, so did the French government. Both sieges were waged on people perceived to be socially and politically dangerous.
