In 1833, Parliament passed the Slavery Abolition Act. From 1 August 1834, slavery was declared abolished across the British colonies. That's the part most of us were taught. The part we skipped is who got paid.
The government set aside £20 million, about 40% of its total annual spending at the time, to compensate the people who had owned human beings for the loss of their "property". The enslaved people themselves received nothing. Freedom wasn't even immediate. Anyone over six became an unpaid "apprentice", still tied to the estates, until the system ended in 1838.
The compensation records survive, and they read almost like a census of slave ownership. The National Archives holds the registers of payments, and UCL's Legacies of British Slavery project used them to trace who received the money and where it went. That turned a line in a textbook into names, estates and fortunes that shaped modern Britain.
Then there's the receipt itself. The money was borrowed, and the debt got rolled over into government bonds for generations, ending up in an undated gilt called the 4% Consolidated Loan. In 2015 the government redeemed that bond, and HM Treasury confirmed in a 2018 Freedom of Information response that the borrowing for the Act was fully repaid in 2015. One honest caveat: Treasury says it can't tell how much of that final bond came from the original 1830s loan. So taxpayers kept servicing the bill for owners' compensation until within living memory, and the people who were enslaved were never on the payee list.
