What appears if you stop in 1858?
The Great Stink belongs to one summer. Bazalgette’s sewers are a construction project spanning years. The timeline puts them side by side while keeping the distinction between event and process.
02 · Written evidence
A manuscript has a copying date. Its words have a longer history.
The Scheian Psalter was copied between 1573 and 1578. The Voroneț Codex has a different dating interval. These bars date surviving records without assigning a birth year to Romanian.
03 · Years with uncertainty
4900–3800 BCE spans more than a thousand years.
Gumelnița spans many generations. Its approximate interval brings together different beginnings and endings at individual sites. The complete project shows the radiocarbon distribution, objects and people that can be distinguished within it.

04 · What kind of evidence?
An image can be precisely dated and still be a caricature.
The year alone does not answer the question. A satirical print, a law, a diary, an inscription and a radiocarbon sample tell us different things. Each project leads to its sources and their limits.

Ancient DNA backs Jordanes on one point. That is about 2% of his book.
A 2026 Nature study supports the first Goths coming from Scandinavia: 24 of 27 people of the Wielbark culture. But the whole Getica, read paragraph by paragraph, shows the departure from the north is about 2% of the book, while about one word in eight is Getic history and legend: Burebista, Deceneus and the Dacian king of AD 86 become Goths.

The lost towns of Dacia, from Ptolemy's numbers
Ptolemy gave two numbers for each of Dacia's 44 towns; 34 have no sure site. Fitted to the towns that have been found and tried on towns held back, the numbers typically miss by 68 km: they point to a district, not a hill.

Every day of wind measured at 32 Romanian weather stations from 1974 to 2025, woven like a folk rug: one row a year, one thread a day.

Why do Brăila’s streets curve toward the Danube?

Timișoara, the city kept at a distance by its own fortress: the 500-Klafter circle on today’s map
Until 1868 building was forbidden within 500 Klafter (948 m) of the fortifications of Timișoara, in western Romania. The city plan of 1853 and the star-shaped fortress of 1788, laid on today’s streets, show the circle: the suburbs of the time stop at it, the old parks round the centre lie inside it, and Fortress Boulevard still runs along its edge. For any street the page gives its distance from the wall and what was drawn there in 1853.

What would you take back in time? Twenty objects and the era where each does the most good
Pick an object, pick an era, watch the tunnel and get a score. Potatoes, rehydration salts and an alphabet stamp set come out on top; the lighter, the gold and the neodymium magnet at the bottom. The ranking follows whether the era can copy the object (ρ = 0.90); how fast it believes you has no link to it (ρ = −0.02). The scores are the author's judgements, checked against 5,000 random weightings and three raters who never saw them.

The Bronze Age collapse, place by place: 153 claimed destructions of about 1200 BCE, each with the clock that dated it
153 destructions are said to have happened at the end of the Bronze Age. Jesse Millek (2023) went back to the excavation reports and keeps 59. A relief map of the eastern Mediterranean shows all of them on a clock from 1300 to 1050 BCE and what dated each: pottery, a text, tree rings or radiocarbon. Only seven have a radiocarbon range for the destruction itself, 84 to 245 years wide; the page shows what they can and cannot say.

On the Danube nearly all the Christian inscriptions date from after 300, and they name soldiers no more often than the frontier’s other inscriptions do.

On Itiner-e, the 2025 map of Roman roads, 57% of the length can be walked to Rome, 37% hangs on two short ferries and 5.9% is on islands. But the same 94% lead to Byzantium too: roads run both ways, and the average kilometre of road is nearer to Byzantium (2,395 km) than to Rome (2,781 km). The distances the Romans wrote on the Peutinger map are compared with the measured roads, and for any town between Scotland and the Nile the map shows its road to Rome.

Power & public life
Where would you draw the line between Romania and Ukraine in the Black Sea?
Romania and Ukraine both claimed 12,162 km² of sea off the Danube Delta. Draw the line where it seems fair to you, then follow the International Court of Justice through its 2009 reasoning, step by step.

Sibiu keeps electing German Forum mayors. At the 2021 census, 0.7% of residents were German
Germans were about two thirds of Sibiu in 1850 and 0.7% of residents at the 2021 census, yet the city has elected the Democratic Forum of Germans in Romania at every mayoral election since 2000. Census data from 1850 to 2021, the votes, and the reasons.
Journeys & encounters
Giurgiu–Ruse: for 59 years, the only bridge between Romania and Bulgaria
Romania and Bulgaria share about 470 km of the Danube. From 1954 to 2013 the Giurgiu–Ruse bridge was the only bridge across it. See the lower Danube in any year since 1409.
Inventions & discoveries
The eclipse tables made for Oradea’s bishop, checked against the Moon
Georg Peuerbach finished his eclipse tables probably in 1459; one version was set on the meridian of Oradea for its bishop. Recomputed today, the two worked examples in his own instructions show the tables’ times 3 to 26 minutes out. See the night of 27–28 December 1460 from your town, and whether Oradea was ever a prime meridian.

Within 44 km of the Black Sea, the Danube still has 290 km to go
Just below Cernavodă, in south-east Romania, the Danube comes within 44 km of the Black Sea (a straight line from the river to the nearest coast), then needs about 290 km more to reach it at Sulina. The walls, the 1860 railway, the Cernavodă bridge and the Danube–Black Sea Canal, dug twice, on one map.
Power & public life
A pound of purple silk was capped at six thousand days’ pay: colours of power from Rome to London
In 301 Rome capped a pound of purple silk at 150,000 denarii, 6,000 days of a farm labourer’s pay. What purple was worth in days of work, what purple and ultramarine were worth in gold or silver, and which colour laws the sources record in Byzantium, Sui and Tang China, Japan and Tudor England.

The Slavic part of Romanian: words, maps and a test on the 1930s villages
How much of Romanian came from the Slavs: 12.2% of basic meanings, about one spoken word in 20–30, Slavic prefixes on Latin roots, and a 1930s village map that tests where each neighbour's words were heard.
Documents & words
The chronicles' hard years, checked against the tree rings
157 records of drought, famine, hard winters, floods and locusts from the written sources of the Romanian lands (111 distinct years), set year by year against what the trees recorded. The droughts show in the rings; the famines are indistinguishable from chance.

Ten true things in history that sound wrong
A Spanish dollar that was American money for 63 years, a doge chosen in ten rounds, a British king of France in 1800: ten facts, each checked against a statute, gazette, table or dataset.

What did it cost in 1985? A Romanian price game, in minutes of work
In communist Romania in 1985, a kilo of sugar cost 50 minutes of work at the average wage; in 2025 it cost 8 minutes. A pack of coffee took 6 hours in 1985 and 1 hour 35 minutes in 2025. Guess the work time for other goods, from the 1985 prices Romania reported to the International Labour Organization and their sources.

Luxury beliefs: how opinions became a sign of rank, from Romanian boyars’ fur hats to today
Rob Henderson’s theory of luxury beliefs, from Veblen and Romanian boyars’ fur hats to smoking and political opinion, tested on data: what graduates say, what they do, and who bears the consequences.

1,487 embroidery patterns at the ASTRA Museum in Sibiu: who sewed them, from whose blouses, and how old the patterns were
From 1954, women and girls in the villages around Sibiu, Făgăraș and Hunedoara copied the patterns of the blouses in their homes onto linen for the museum in Sibiu. Many cards say who sewed, at what age, whose blouse she copied and how old the pattern was. All 1,487 patterns, on one wall.
About the collection
The timeline selects periods explicitly dated in the projects. Bars show the period discussed, not the uninterrupted existence of a city, institution or process. A single year marks a dated event or record. Overlap in time does not establish causation. The collection also includes all history projects without a period selected for this timeline.
