In addition to this title, the Dutch king also granted Wellington 1,050 hectares (2,600 acres) of land and a yearly endowment of 20,000 guilders.

To this day the Dukes of Wellington retain the title Prince of Waterloo,[1] and enjoy an annual income of around £100,000 from the longstanding tenants occupying the land.

[vague] After the Belgian independence the endowment was by the Treaty of London included in the public debt to be assumed by the new Kingdom of Belgium.

The land held by the Prince of Waterloo came under pressure from retired Belgian senator Jean-Emile Humblet in 2001.

But some Belgian taxpayers, led by Humblet, claimed the deal did not reflect the value of the land and drew attention to the wider issues surrounding the original agreement, contending that Belgium was effectively coerced into accepting the terms of the original agreement, because it could not afford to offend Britain.
