In the summer of 1928, Jawaharlal Nehru, apart from his ten-year-old daughter Indira, wrote her thirty letters. They tell the story of the earth from its formation through the evolution of life to early humans and the first civilizations. He had them printed in 1929, which makes the book a concrete case of a political leader teaching a child world history as a single connected story rather than as memorized dates and national glories.
Where no written records exist, the past can still be read from rocks, mountains, rivers, fossils and animal bones. They are documents that record what happened to them. A small rounded pebble, for example, tells that it was once a jagged piece of rock broken from a mountain and slowly worn smooth by water carrying it downstream. Reading the physical world this way turns ordinary objects into evidence and extends history back before humans could write.
The patriarch or chief of early tribes was originally chosen by the group because he was the best organizer or fighter. His job was to serve the community's common interest. As settled agriculture produced surpluses and the office passed from father to son, the chief came to hold the tribe's wealth as his own and to rule rather than serve. People forgot that their rulers had been chosen by them, and kings later called their authority divine.
Related words across distant languages show that peoples who now see themselves as separate come from common ancestors. Examples are Sanskrit pitar, Latin pater and English father, and similarly the words for mother. Because racial and national divisions came later and go less deep than this common origin, humanity is best understood as one large family.
