The First Queens
The Early Dynastic Period 3100-2650 BC
For ancient Egyptian women, the advent of agriculture in around 5500 BC and consequent village settlement had been a mixed blessing. The new diet raised female fertility so that women were now exposed to the perils of an annual pregnancy. More children made housework a full-time occupation, and it seems likely that this is the time when women's domestic duties became clearly defined in the ancient Egyptian mind.
