We live in an era when trading our information for access can feel harmless or inevitable – yet from targeted advertising to mass surveillance, data shapes the course of our lives. How did it gain the power it now holds over us?

Long before writing existed, at the dawn of civilisation in Mesopotamia, rulers pressed marks into clay to keep track of land, people and grain. To rule, they had to keep count. It is no accident, then, that the first written name in human history was neither a god nor a king, but an accountant. As ships and navigation expanded our horizons, a new age of European empires took control of more than 80 per cent of the world’s surface, using colonial censuses, maps and ledgers to decide who belonged, who owed, and who could be sacrificed. Today, a handful of private brokers increasingly define what we see and what is real.
