Next, due to the immense size of Alexander’s empire, there was a tremendous issue: his subjects spoke many different languages and had different cultural customs. Alexander encouraged the blending of various cultures throughout his empire and combined them to form the now known Hellenistic world. During his rule, Alexander tried to fuse Persian and Greek cultures, he had planned to unify parts of the large empire by the intermarriage of Macedonian and Persian nobles. In an attempt to do this, he married Roxanne of Bacteria and later a Persian princess and encouraged his commanders and officers to marry people of different cultures as well. Throughout his empire, additionally, Alexander established Greek as the main language. This resulted in almost everyone over the vast empire spoke one language, and thus was unified culturally. In addition to this, having one language over a large span of land facilitated and expanded commerce and communication between different regions, resulting in a more closely connected world that could communicate more effectively and efficiently than ever before. Through this communication, Greek, Persian, and Indian art, philosophy, science, math, architecture, and traditions were blended through contact between people ruled by Alexander the Great and spread by those that traveled throughout his empire. In contrast, the Roman empire was more culturally intolerant. Although the Romans did blend cultures from peoples they conquered, it was of a much lesser extent, and the cultural intolerance of the Romans was clearly indicated through the Christian persecutions. In an empire as large of Rome, there are a plethora of different cultures living in one area. When new lands were conquered, the Romans would incorporate the deities of the regions into their myriad of gods. This is because this indicated that the conquered lands agreed with Romans polytheistic beliefs, indicating unification. However, when Christianity started to emerge as a new religion, this polytheism was threatened. When Christianity started to gain a larger following, Romans started to persecute Christians. This was due to the fact that Christians would not accept Roman polytheistic virtues. The Christians faced torturous abuse, such as imprisonment, being burned alive, eaten by lions, and crucified among many others. It is evident that these empires are drastically different in their ways of cultural diffusion. Alexander the Great wanted everyone to be unified with one language, which then allowed for the spread of different religions and extensive trade. On the other hand, the Roman Empire wanted all of its subjects to comply with one religion and would go to distant, pernicious lengths to achieve that. These empires are different because it was incorporated into Alexander’s government agenda to have diversity within his large empire because he believed it would keep them unified, whereas Rome’s government agenda was not focused on diversity within the empire rather, having everyone living under the same rules.
