2. EMPEROR SHENZONG OF SONG – $30+ TRILLION
Shenzong ruled China from 1067-1085 during the ‘Peaceful Prosperity’ and ‘Primary Abundance’ eras when he controlled around 30% of global GDP, the equivalent of $30+ trillion today. Adept at collecting taxes, the emperor’s administration wasn’t all take, take, take however. Its famous New Policies, which helped improve the lives of the poor, are seen as a forerunner of the modern welfare state.
