From Window Tax to Bedroom Tax
Window Tax....... The tax was introduced in England and Wales under the An Act for granting to His Majesty several Rates or Duties upon Houses for making good the Deficiency of the clipped Money in 1696 under King William III and was designed to impose tax relative to the prosperity of the taxpayer, but without the controversy that then surrounded the idea of income tax. The Act was repealed in 1851.

This measure only applies to housing benefit claimants of working age, and is commonly referred to as the bedroom tax, size criteria, under-occupation penalty or removal of the spare room subsidy.
