It's also worth noting that Nathan Mayer Rothschilds profited from the outlawing of slavery in the United Kingdom through loans to the British government to compensate former slave traders for their financial loss from the abolition of their slaves. This was not paid back by British taxpayers until 2015... A lot of people on this board know about this, but it's always worth mentioning again.

"o finance the payments, the British government took on a £15 million loan, finalised on 3 August 1835, with banker Nathan Mayer Rothschild and his brother-in-law Moses Montefiore; £5 million was paid out directly in government stock, worth £1.5 billion in present day.[27] The money was not paid back by the British taxpayers until 2015,[28] when the British Government decided to modernise the gilt portfolio by redeeming all remaining undated gilts. The long gap between this money being borrowed and its repayment was due to the type of financial instrument that was used, rather than the amount of money borrowed.[29]"
