The history of Royal Prussia, which fell into the Polish orbit, is little known to those who approach the Prussian story from an exclusively German perspective. (The subject was actively suppressed by bans and book-burnings when the Hohenzollerns eventually took over.) Yet for 300 years this 'Other Prussia' flourished, not only as a separate institutional entity, but as the source of a separate political ideology and culture, based on concepts of freedom and liberty. Though the population was ethically mixed, Polish and German - with a strong German predominance in the cities - the corporate identity and fierce local patriotism of Royal Prussia digressed markedly from the values with which the name of 'Prussia' is usually associated.
