How Successful Were Maria Theresa's Reforms On Tax And Economy?

The reform that meant that nobles and clergy would have to pay taxes at only half the rate paid by the peasants aroused predictable opposition from the estates. It was argued against on the practical grounds that it would deprive the assemblies (diets) of their power to levy and collect taxes. Maria Theresa, however, was able to overcome all protests. Prussia's conquest of Silesia made it difficult to resist the logic of Haugwitz's proposal to change the tax system.

The estates could not deny the state needed more taxes in order to protect the territory from further Prussian aggression. It is therefore arguable Fredrick's invasion of Silesia had been a blessing in disguise. Maria Theresa had been forced to solemnly declare swear to uphold all existing rights and privileges of the Hungarian diet. She didn't consider breaking this oath as she felt strongly that it was her honour that distinguished her from other rulers.
