What is the Holocene?

The Holocene is the current geological epoch, which began approximately 11,700 years ago when the last ice age ended. It is characterized by a remarkably stable global climate that enabled the rise of agriculture, cities, and human civilization as we know it.

What happened during the Holocene?

During the Holocene, humans transitioned from nomadic hunter-gatherers to settled agricultural societies. This epoch saw the invention of writing, the founding of the first cities, the rise and fall of empires, the Scientific Revolution, the Industrial Revolution, and the emergence of global civilization — all within a narrow band of climate stability.

How long is the Holocene?

The Holocene spans approximately 11,700 years, from the end of the last glacial period to the present. This interactive timeline covers 15,000 years, extending back into the Late Pleistocene to show the transition from ice age conditions into the stable Holocene climate.

Interactive Timeline

The Holocene

These are the past 15,000 years.
Each row is a century. Each square is a year.

Approximately 11,700 years ago, the ice retreated and the Earth entered a uniquely stable climate epoch — the Holocene. Within this narrow window, humans planted the first seeds, founded the first cities, devised the first alphabets. Everything we have built rests on this stability.

About The Holocene

With the support of the
Potsdam Institute for Climate Impact Research (PIK)

An interactive visualization of 15,000 years of human history — from the retreat of Ice Age glaciers through the rise and fall of civilizations to the present day.

How to navigate

The grid is a map of time. Each small square is one year. Each row is a century (100 years). The full grid spans 151 centuries, from 13,000 BCE to 2026 CE.

What you see

Colored squares: Each year's color reflects its epoch and position. Brighter squares contain recorded events.
Span bars: Thin colored lines beneath years mark multi-year periods — empires, wars, movements, ages. Examples: Roman Republic and Empire (509 BCE–476 CE), World War II (1939–1945), Atlantic Slave Trade (1526–1867).
Event dots: White indicator marks appear on years that contain one or more point events — specific moments like inventions, battles, or discoveries.

The three epochs

Pleistocene: 13,000–9,700 BCE. The tail end of the last Ice Age. Humans live as hunter-gatherers; early settlements like the Natufian culture emerge.
Holocene: 9,700 BCE–1950 CE. The warm, stable climate epoch. Agriculture, writing, cities, empires, science, and industry all unfold here. The gradient reflects three formally defined stages: Greenlandian (Early, teal-green), Northgrippian (Middle, green), and Meghalayan (Late, gold-amber).
Anthropocene: 1950 CE–present. The era of human-scale planetary impact: nuclear technology, mass consumption, climate change, and the digital revolution. The violet palette marks a sharp break from the warm Holocene.

Controls

Thematic lenses: Filter events by category — Society, Science/Tech, Earth, Ecology, Culture, Conflicts, or Exploration. Only matching events and spans are shown.
BCE/CE ↔ HE toggle: Switch between the conventional calendar (BCE/CE) and the Holocene Era calendar, which adds 10,000 years so that all dates are positive. Year 1 CE = 10,001 HE.
Birth year: Enter your birth year to highlight your lifetime on the grid and see it in the context of deep history.
Color modes: Switch between three background coloring schemes: Epochs colors each year by its geological epoch (Pleistocene, Holocene, Anthropocene). Temp maps reconstructed global mean temperature anomaly onto a blue-to-red gradient. CO₂ maps atmospheric carbon dioxide concentration onto a purple-to-yellow gradient. The legend bar at the bottom shows the active scale with key reference marks.

Data

The timeline contains 865 events, 238 historical figures, and 173 multi-year spans across 13 categories. Content aims for global coverage across all epochs, with particular attention to non-Western civilizations, women in history, and environmental milestones. This database is shared with the Corridor of Life climate timeline.

Climate data sources

Temperature: Osman et al. (2021), "Globally resolved surface temperatures since the Last Glacial Maximum", Nature 599, 239–244. Supplemented by HadCRUT5 (Morice et al. 2021) for 1850–2025. Baseline: 1850–1900 mean (pre-industrial reference period, per IPCC AR6). Values are anomalies in °C relative to this baseline.
CO₂: Bereiter et al. (2015), "Revision of the EPICA Dome C CO₂ record", Geophysical Research Letters 42, 542–549. Ice core composite covering 800,000 years; interpolated annually for this visualization. Supplemented by Mauna Loa Observatory (NOAA GML) for 1958–2025. Pre-industrial baseline: ~280 ppm (circa 1750 CE).

Both datasets are interpolated to annual resolution for the timeline grid.
