Every battle in history, mapped

Wikidata knows of 20,202 battles. I mapped the 13,712 with a place and a date, from 3001 BCE to 2026, to find the most fought-over places on Earth, follow the centre of war century by century, and see how much the famous map is really a map of who wrote things down.

I mapped the world’s inventions from the first stone tools to the web: farming began in 11 places, writing in 4, and the centre of invention moved from Mesopotamia to China, Europe and North America. The open record of it is 91% Europe and North America.

The Earth at night: where the world lit up and where it went dark

Seen from space, the planet gave off 57% more light in 2024 than in 2012. Nepal’s light grew 9.3 times and Africa’s cities blazed up, while war halved the light of Ukraine and Yemen, and new LED street lamps made France look 40% darker than it is.
