However, Frederick looked upon many of his new Polish citizens with carefully concealed scorn. Frederick's long-term goal was to remove the Poles from the conquered region and colonize it with Germans, who he considered better workers. Frederick invited thousands of German colonists into the conquered territories by promises of free land. He compared the Polish peasants unfavorably with the Iroquois, and named three of his new settlements after colonial areas of North America: Florida, Philadelphia and Saratoga. He aimed to expel the Polish nobles—who were viewed as wasteful, lazy, and negligent—using an oppressive tax system and to mix the remaining rural Poles with Germans so the Poles could learn "industriousness", "cleanliness, and orderliness" and acquire a "Prussian character". By such means, Frederick boasted he would "gradually...get rid of all Poles".
