Comparing the World's States Around 1200

Every state faces the same two tasks: pull wealth from the people who produce it, and convince those people the ruler deserves to take it. Song China ran a salaried bureaucracy that collected coin taxes from a monetized economy, backed by a written legal code and officials chosen for administrative skill. The Delhi Sultanate, ruling a Hindu majority from a Muslim court, leaned on military force and land-revenue assignments, with Islam supplying the ruling class's legitimacy. Mali taxed the gold-salt trade passing through its cities and had its rulers perform visible Islamic piety, like Mansa Musa's pilgrimage and mosque-building, to bind far-flung merchants and scholars to the throne. The Inca had little coined money at all, so they ran the mit'a, a labor draft that pulled workers from every village to build roads, terraces, and storehouses, with the ruler's divine descent from the sun god justifying the claim on their labor.

Tribute, coin taxes, and labor drafts look different but do the same job: convert something people have, goods, money, or time, into resources a capital can spend on armies, officials, and monuments. Which method a state picks depends on what it has plenty of. Mali had trade routes to tax. Song China had a cash economy to tax directly. The Inca had labor and terrain but no widespread currency, so they taxed time instead.

This comparison sets up why reach differs: a state funded by portable coin can pay distant armies and officials, while one funded by labor drafts or local tribute struggles to project power far from its base, a limit that becomes visible once these regions start colliding after 1450.
