42 events, chosen for reliable evidence and historical weight. Labels apply to each field, not to the whole event: a date can be verified while a death toll stays uncertain. Ranges mean credible sources disagree. This is not a ranking.

  1. 1346 – 1353 ESTIMATED · Epidemic

    Black Death

    A plague pandemic, caused by the bacterium Yersinia pestis, that spread from the Black Sea region across Europe, Western Asia and North Africa between 1346 and 1353.

    Deaths
    25,000,000–50,000,000 ESTIMATED
    Counted
    Deaths in Europe only; no comprehensive estimate exists for Western Asia and North Africa. Low end: Britannica (about 25 million, 1347–1351); high end: Benedictow's synthesis of about 60% of an estimated 80 million Europeans (about 50 million), as summarised by Our World in Data.

    Europe, Western Asia and North Africa VERIFIED
    Evidence and sources (2)

    No censuses existed; tolls are extrapolated from tax and rent registers, parish records and archaeology covering parts of Spain, Italy, France and England. Older estimates put European mortality at 25–33%, recent syntheses (Aberth, Benedictow) at 51–60%; dates also vary (1347–1351 for Europe, 1346–1353 for the full spread).

    1755 Lisbon earthquake

    On the morning of 1 November 1755, All Saints' Day, an offshore Atlantic earthquake shook Lisbon, followed by a tsunami and fires that burned for about six days.

    Deaths
    50,000–70,000 ESTIMATED
    Counted
    Deaths from shaking, tsunami and fire combined. NOAA's tsunami table lists 50,000 (may include earthquake deaths); Britannica gives about 60,000 in Lisbon alone; USGS lists 70,000.

  3. 1845 – 1852 VERIFIED / ESTIMATED · Other

    Great Famine (Ireland)

    Repeated failures of Ireland's potato crop from late blight, beginning in 1845, caused famine and epidemic disease; Ireland's population fell from about 8.4 million in 1844 to 6.6 million by 1851.

    Deaths
    1,000,000 ESTIMATED
    Counted
    Excess deaths from starvation and famine-related disease (typhus, typhoid, dysentery), about one million per both Britannica (Joel Mokyr) and Cormac Ó Gráda (EH.Net). Excludes some two million emigrants, averted births and famine-related deaths abroad.
    Where
    Ireland VERIFIED
    Evidence and sources (2)

    Without civil registration, excess mortality cannot be calculated directly; one million is an informed estimate. End date differs by source: Britannica dates the famine 1845–49, Ó Gráda 1846–52 because high mortality persisted in western counties to 1850–51.

    Taiping Heavenly Kingdom Movement

    A movement against the Qing dynasty led by the Taiping Heavenly Kingdom, which held Nanjing as its capital until Qing forces recaptured it in 1864. The CPC's 2021 resolution lists it among movements that rose to save the nation from peril but ended in failure.

    Deaths
    20,000,000–30,000,000 ESTIMATED
    Counted
    Deaths from fighting, massacres, famine and disease. Low end: Encyclopaedia Britannica (an estimated 20 million) and University of Cambridge (at least 20 million, about 5% of the empire's population). High end: Tobie Meyer-Fong, What Remains (Stanford University Press, 2013), citing conventional figures of 20 to 30 million. No official PRC death figure was found.
    Where
    Southern and central China VERIFIED
    Evidence and sources (4)

    There was no reliable census, so totals are projections from population loss; Meyer-Fong notes that a precise or even approximate count is impossible. Most deaths are attributed to famine and disease rather than combat.

    American Civil War

    A war between the United States (the Union) and eleven secessionist Southern states (the Confederacy) over secession and slavery, ending in Union victory and the abolition of slavery.

    Deaths
    618,222–750,000 ESTIMATED
    Counted
    Military deaths from combat and disease, with some civilian deaths in census-based figures. Low end: the traditional count of 618,222; high end: J. David Hacker's census-based estimate of about 750,000 (range 650,000–850,000). A 2024 full-census study (PNAS) estimates 698,000.
    Where
    United States VERIFIED
    Evidence and sources (2)

    The traditional figure comes from late-19th-century tallies of incomplete military records; census-based methods compare male and female survival across the 1850s–1870s and yield higher totals. About two in three soldiers who died were killed by disease.

    1902 eruption of Mount Pelée

    At about 8:00 a.m. on 8 May 1902, a pyroclastic current from Mount Pelée reached the town of Saint-Pierre, Martinique, within minutes and destroyed it.

    Deaths
    28,000–30,000 ESTIMATED
    Counted
    Deaths from the 8 May pyroclastic current. Lacroix (1904), cited in Frontiers in Earth Science (2020), estimated 28,000–29,000; USGS lists 30,000 (29,025 per Blong 1984).

    Sinking of the Titanic

    The British liner Titanic struck an iceberg late on 14 April 1912 on its maiden voyage from Southampton to New York and sank at 2:20 a.m. on 15 April in the North Atlantic.

    Deaths
    1,490–1,517 ESTIMATED
    Counted
    Passengers and crew lost. The U.S. Senate inquiry found 1,517 and the British Board of Trade inquiry 1,503; their official reports revised these to 1,500 and 1,490. NOAA states more than 1,500 of about 2,240 aboard died.

    First World War

    A global war fought chiefly between the Allied Powers and the Central Powers, beginning with Austria-Hungary's declaration of war on Serbia and ending in the armistice of November 1918.

    Deaths
    16,500,000–21,500,000 ESTIMATED
    Counted
    Military plus civilian deaths, excluding the 1918 influenza pandemic. Low end: LSHTM (about 16.5 million, about 7 million of them civilians); high end: Britannica's about 8.5 million military dead plus about 13 million civilian deaths.

    Evidence and sources (4)

    Military deaths rest on post-war national returns (the 1924 US War Department table gives 8,528,831); civilian deaths from famine, disease and violence are far less certain, which drives the spread. The armistice of 11 November ended fighting on the Western Front; peace treaties followed in 1919.

    Halifax Explosion

    The French munitions ship Mont-Blanc collided with the Norwegian ship Imo in Halifax Harbour on 6 December 1917, caught fire and exploded, levelling much of the city's north end.

    Deaths
    1,631–1,946 ESTIMATED
    Counted
    Direct deaths from the blast, tsunami and fires, including those who died of injuries in the following days. 1918 morgue records listed 1,631 known dead or missing; the count was revised to 1,946 by 2004 (The Canadian Encyclopedia). Britannica gives nearly 2,000.
    Where

    Evidence and sources (2)

    Identification was incomplete amid the destruction, so later research raised the toll above the original morgue count; about 9,000 were injured.

    1918 influenza pandemic

    An influenza A(H1N1) pandemic that spread worldwide in waves from 1918, infecting an estimated 500 million people, about one third of the world's population at the time.

    Deaths
    17,000,000–100,000,000 ESTIMATED
    Counted
    Pandemic influenza deaths worldwide. CDC gives 'at least 50 million' and a CDC journal article 20–100 million; Our World in Data reports Johnson and Mueller (50 million, possibly up to 100 million) and Spreeuwenberg et al. 2018 (about 17 million, likely an underestimate).

    Worldwide VERIFIED
    Evidence and sources (3)

    Death registration was missing or incomplete in much of the world, so totals are compiled from vital records and regional excess-mortality estimates. The low estimate extrapolates from high-income countries; higher estimates reflect heavier mortality in poorer regions such as India. Most sources date the main pandemic to 1918–1919, with later waves into 1920.

    Holodomor

    Famine in Soviet Ukraine in 1932–33, peaking in spring 1933, that followed forced collectivisation and grain-requisition policies of the Soviet leadership.

    Deaths
    2,600,000–5,000,000 ESTIMATED
    Counted
    Direct excess deaths in Soviet Ukraine only; lost births are excluded. Demographic estimates range from 2.6 million (Vallin, Meslé et al. 2002) to 5 million (Conquest 1986), as summarised by Rudnytskyi et al. (Canadian Studies in Population, 2015) and Levchuk et al.

    Where
    Ukrainian SSR, Soviet Union (present-day Ukraine) VERIFIED
    Evidence and sources (6)

    No official toll exists and Soviet census and vital-registration data were incomplete or falsified, so totals come from population reconstructions that differ mainly in how they treat migration.

    Sinking of the MV Le Joola

    The overloaded Senegalese government ferry Joola, sailing from Ziguinchor to Dakar, capsized in a storm off The Gambia on the night of 26 September 2002; 64 people survived.

    Deaths
    1,863 ESTIMATED
    Counted
    Official Senegalese toll of dead and missing as reported by BBC News and geographer Karen Barton (University of Northern Colorado). Labelled estimated because many passengers were unticketed and the ferry carried about three times its rated capacity, so the true number aboard is uncertain.

    The 1,863 figure is the government count used consistently by the press and scholarship; the absence of a reliable passenger list leaves room for a higher true toll.

    2003 European heat wave

    Exceptional heat across western and southern Europe in summer 2003, peaking in the first half of August, was followed by a sharp rise in deaths, especially among older people.

    Deaths
    71,449 ESTIMATED
    Counted
    Excess deaths (not directly certified heat deaths), June–September 2003, in the 12 affected countries of a 16-country EU-funded study (Robine et al., 2008). About 45,000 occurred in August; the authors say the total is likely an underestimate because the Balkans and Greece were not covered.
    Where
    Western and southern Europe (notably France, Italy, Spain, Germany, Portugal) VERIFIED
    Evidence and sources (2)

    Excess mortality is measured against 1998–2002 averages, so totals depend on the period and countries studied; earlier August-only estimates of 27,000–40,000 are not directly comparable. The sharpest phase ran from 3 to 16 August.

    2004 Indian Ocean earthquake and tsunami

    A magnitude 9.1 earthquake off northern Sumatra on 26 December 2004 generated a tsunami that struck coasts across the Indian Ocean, from Indonesia and Sri Lanka to East Africa.

    Deaths
    227,899 ESTIMATED
    Counted
    Dead or missing and presumed dead in 15 countries (Indonesia 167,540; Sri Lanka 35,322; India 16,269; Thailand 8,212; others smaller), from the NOAA/NCEI Global Historical Tsunami Database. NCEI's event summary gives 227,898 because its narrative country list omits one death in Madagascar.

    Figures are national tallies compiled by NOAA/NCEI and include the missing, so they are estimates rather than confirmed burials. No separate earthquake toll exists because the tsunami arrived within about 20 minutes.

    2010 Haiti earthquake

    A magnitude 7.0 earthquake struck about 25 km west-southwest of Port-au-Prince on the afternoon of 12 January 2010, collapsing much of the capital and nearby Léogâne and Jacmel.

    Deaths
    46,000–316,000 UNCERTAIN
    Counted
    Direct deaths. High end: the Haitian government's official figure of 316,000, announced in January 2011 and used by NOAA/NCEI (an earlier government figure was 222,570). Low end: a draft survey-based report commissioned by USAID (LTL Strategies, 2011) estimating 46,000–85,000, which USAID did not endorse.

    Mass burials without documentation made a definitive count unlikely. The official toll and the survey-based estimate differ several-fold, and both have been criticised for method.

    2011 Tōhoku earthquake and tsunami

    A magnitude 9.0–9.1 earthquake off the Pacific coast of north-eastern Japan on 11 March 2011 generated a tsunami that devastated the Tōhoku coast and led to the Fukushima Daiichi nuclear accident.

    Deaths

    Deaths
    11,308–11,325 VERIFIED
    Counted
    Reported deaths among suspected, probable and confirmed cases. WHO and CDC (2016) give 11,325 including 15 deaths outside the three main countries; CDC's current outbreak history lists 11,308 for Guinea, Liberia and Sierra Leone.

    Counts come from ministries of health via WHO; weak surveillance means true deaths were probably higher. The index case is believed to date to December 2013. WHO lifted the emergency on 29 March 2016, and the outbreak was declared over in June 2016 after flare-ups.

    COVID-19 pandemic

    The pandemic of coronavirus disease caused by SARS-CoV-2, shown here as the period WHO treated it as a public health emergency of international concern, from 30 January 2020 to 5 May 2023.

    Deaths
    13,300,000–16,600,000 ESTIMATED
    Counted
    WHO estimate of excess mortality (deaths above expected, direct and indirect) for 1 January 2020 to 31 December 2021 only: about 14.9 million, range 13.3–16.6 million. It covers part of the emergency period, so it understates the toll to May 2023; it is not a count of confirmed COVID-19 deaths.
    Where
    Worldwide VERIFIED
    Evidence and sources (4)

    WHO and UN DESA modelled excess deaths because many countries lack reliable death registration; reported COVID-19 deaths are far lower. WHO characterised COVID-19 as a pandemic on 11 March 2020. Other models (IHME, The Economist) give higher totals, and WHO has published no comparable estimate to May 2023.
