Answer:
Islam and the Arabic language have had a profound influence on the region. The spread of Islam throughout the Middle East brought with it many new ideas, customs, architecture, art, and literature that had a lasting impact on the region. Additionally, Arabic became a vital lingua franca in much of the Middle East due to its status as a language of scripture (the Qur'an) and an official language within many Islamic countries. This led to an era of increased cultural exchange between different parts of the region which helped shape many aspects of modern culture in those countries today.
