With the acquisition of the Rhenish and Westphalian territories, Prussia gained not only in territorial size and population but also, crucially, in economic power and potential. Not only was Prussia now more equal to Austria in simple demographic terms; Prussia also was poised to outstrip Austria in economic development, a major factor in the century of industrialisation. Constitutionally, however, both Prussia and Austria remained relatively conservative. Prussia did not gain a united parliament, and although reforms were continued in certain provinces (with the western provinces, which were not engaged in a programme of reform, nevertheless continuing to be more progressive), centrally the programme of reforms was dropped by King Frederick William III. Major reformers had been dismissed from office by 1819–20. In Austria, the absence of a perceived need for centralisation in response to territorial or other changes, and the earlier reforms under Joseph II, added up to a programme of conservatism and inactivity in the post-Napoleonic period.
