Throughout the Hellenistic world, these Greco-Macedonian colonists considered themselves by and large superior to the native "barbarians" and excluded most non-<answer>Greek</answer>s from the upper echelons of courtly and government life. Most of the native population was not Hellenized, had little access to <answer>Greek</answer> culture and often found themselves discriminated against by their Hellenic overlords. Gymnasiums and their <answer>Greek</answer> education, for example, were for <answer>Greek</answer>s only. <answer>Greek</answer> cities and colonies may have exported <answer>Greek</answer> art and architecture as far as the Indus, but these were mostly enclaves of <answer>Greek</answer> culture for the transplanted <answer>Greek</answer> elite. The degree of influence that <answer>Greek</answer> culture had throughout the Hellenistic kingdoms was therefore highly localized and based mostly on a few great cities like Alexandria and Antioch. Some natives did learn <answer>Greek</answer> and adopt <answer>Greek</answer> ways, but this was mostly limited to a few local elites who were allowed to retain their posts by the Diadochi and also to a small number of mid-level administrators who acted as intermediaries between the <answer>Greek</answer> speaking upper class and their subjects. In the Seleucid empire for example, this group amounted to only 2.5 percent of the official class.
