Spanish flu, also known as the Great Influenza epidemic or the 1918 influenza pandemic, was an exceptionally deadly global influenza pandemic caused by the H1N1 influenza A virus. The earliest documented case was March 1918 in Kansas, United States, with further cases recorded in France, Germany and the United Kingdom in April. Two years later, nearly a third of the global population, or an estimated 500 million people, had been infected in four successive waves. Estimates of deaths range from 17 million to 50 million, and possibly as high as 100 million, making it one of the deadliest pandemics in human history. The name 'Spanish flu' is a misnomer, rooted in historical othering of infectious disease origin, which is now avoided. The pandemic broke out near the end of World War I, when wartime censors suppressed bad news in the belligerent countries to maintain morale, but newspapers freely reported the outbreak in neutral Spain. These stories created a false impression of Spain as the epicenter, so press outside Spain adopted the name 'Spanish' flu. Limited historical epidemiological data make the pandemic's geographic origin indeterminate, with competing hypotheses on the initial spread.Most influenza outbreaks disproportionately kill the young and old, with a higher survival rate in-between, but this pandemic had unusually high mortality for young adults. Scientists offer several explanations for the high mortality, including a six-year climate anomaly affecting migration of disease vectors with increased likelihood of spread through bodies of water. The virus was particularly deadly because it triggered a cytokine storm, ravaging the stronger immune system of young adults, although the viral infection was apparently no more aggressive than previous influenza strains. Malnourishment, overcrowded medical camps and hospitals, and poor hygiene, exacerbated by the war, promoted bacterial superinfection, killing most of the victims after a typically prolonged death bed.The 1918 Spanish flu was the first of three flu pandemics caused by H1N1 influenza A virus; the most recent one was the 2009 swine flu pandemic. The 1977 Russian flu was also caused by H1N1 virus, but it mostly affected younger populations. The ongoing pandemic of COVID-19, which began in December 2019 and is caused by SARS-CoV-2, is the deadliest respiratory virus pandemic since the Spanish flu.

The Bengal Famine of 1770 (Bengali: Chiẏāttôrer mônnôntôr, lit. The Famine of 76) was a famine that struck the Bengal region between 1769 and 1770 (1176 to 1177 in the Bengali calendar) and affected some 30 million people. It occurred during a period of dual governance in Bengal. This existed after the East India Company had been granted the diwani, or the right to collect revenue in Bengal by the Mughal emperor in Delhi, but before it had wrested the nizamat, or control of civil administration, which continued to lie with the Mughal governor, the Nawab of Bengal.Crop failure in autumn 1768 and summer 1769 and an accompanying smallpox epidemic were thought to be the manifest reasons for the famine. The Company had farmed out tax collection on account of a shortage of trained administrators, and the prevailing uncertainty may have worsened the famine's impact. Other factors adding to the pressure were: grain merchants ceased offering grain advances to peasants, but the market mechanism for exporting the merchants' grain to other regions remained in place; the Company purchased a large portion of rice for its army; and the Company's private servants and their Indian Gomasthas created local monopolies of grain. By the end of 1769 rice prices had risen two-fold, and in 1770 they rose a further three-fold. In Bihar, the continual passage of armies in the already drought-stricken countryside worsened the conditions. The Company provided little mitigation through direct relief efforts; nor did it reduce taxes, though its options to do so may have been limited.By the summer of 1770 people were dying everywhere. Although the monsoon immediately after did bring plentiful rains, it also brought diseases to which many among the enfeebled fell victim. For several years thereafter piracy increased on the Hooghly river delta. Deserted and overgrown villages were a common sight. Depopulation, however, was uneven, affecting north Bengal and Bihar severely, central Bengal moderately, and eastern only slightly. The recovery was also quicker in the well-watered Bengal delta in the east.Between seven and ten million people—or between a quarter and third of the presidency's population—were thought to have died. The loss to cultivation was estimated to be a third of the total cultivation. Some scholars consider these numbers to be exaggerated in large part because reliable demographic information had been lacking in 1770. Even so, the famine devastated traditional ways of life in the affected regions. It proved disastrous to the mulberries and cotton grown in Bengal; as a result, a large proportion of the dead were spinners and weavers who had no reserves of food. The famine hastened the end of dual governance in Bengal, the Company becoming the sole administrator soon after. Its cultural impact was felt long afterwards, becoming the subject a century later of Bankim Chandra Chatterjee's influential novel Anandamath.
