The Last Chains
How long the argument took to reach every country, and where it has not arrived
The scribes had won the argument two centuries earlier. The argument had not yet reached every country. This is the timeline Chapter 11 points to, and the size of the river before the chains came off.
Supports Chapter 11, “The Stolen River.” The printed book points here for the detail it no longer carries.
The timeline
| Year | What happened |
|---|---|
| 1847 | The last year the Istanbul slave market operated openly. The Ottoman Empire maintained slavery as a functioning institution throughout the nineteenth century; the Tanzimat reforms began a slow, partial process of restriction. |
| 1865 | The Thirteenth Amendment abolishes slavery in the United States. |
| 1922 | The Ottoman Empire falls, never having fully abolished the institution. |
| 1962 | Saudi Arabia abolishes slavery, ninety-seven years after the Thirteenth Amendment. Yemen abolishes it the same year. |
| 1981 | Mauritania, in West Africa, becomes the last country on earth to officially abolish slavery. |
| 2007 | Mauritania passes the criminal laws to enforce the ban, twenty-six years later. |
| 2010 | A United Nations mission concludes that de facto slavery continues to exist in Mauritania. |
| 2021 | The International Labour Organization estimates fifty million people living in what it classifies as modern slavery. |
The present tense
That is not a historical residue. It is a current condition: debt bondage in South Asian brick kilns, forced labor on Gulf construction sites, domestic workers whose passports are held by their employers, children in cobalt mines in the Democratic Republic of the Congo.
| ILO 2021 estimate | People |
|---|---|
| Forced labor | 28 million |
| Forced marriage | 22 million |
| Total in modern slavery | 50 million |
How big the river was
Before abolition, the stolen river was enormous. The book’s earlier edition measured it this way: Russia’s serfs at thirty-eight percent of European Russia, and the American South at thirty-three to forty-seven percent, depending on the state. Chapter 11 still carries Russia’s thirty-eight percent where it tells the Russian case.
Checking in progress. The range for the American South is under review. A project review of the chapter (2026-09-22) read the 1860 census as putting the most heavily enslaved states above the top of this range. The figure is shown as the book stated it until the check is finished.
