Answer:
There have been several events that have contributed to cultural change in Southwest Asia, so it is difficult to identify just one event as the most responsible. However, one event that had a significant impact on the region was the Islamic conquests of the 7th and 8th centuries.
With the spread of Islam across Southwest Asia, many aspects of local cultures were influenced and changed. Islamic values and beliefs, such as the importance of prayer, charity, and pilgrimage, became prominent in the region. Arabic, the language of the Quran, became a unifying language across the Islamic world and a major influence on the languages spoken in Southwest Asia.
Additionally, the Islamic Golden Age, which spanned from the 8th to the 13th centuries, brought about significant advancements in fields such as mathematics, astronomy, medicine, and literature. These developments had a lasting impact on the cultural and intellectual landscape of Southwest Asia and beyond.
