In which country did the Bahá'í faith originate?

The Bahá'í faith originated in Persia, which is the historical name for Iran. This religion emerged in the mid-19th century when a Persian nobleman named Bahá'u'lláh declared himself as a prophet and messenger of God. The Bahá'í faith emphasizes the unity of all people and religions, and its teachings are rooted in principles of justice, equality, and global unity.

In contrast, Turkey, Egypt, and India, while culturally significant and home to various religions, are not the birthplace of the Bahá'í faith. Turkey is famously known for its role in the Ottoman Empire, Egypt has its own rich religious history primarily involving Islam and ancient polytheistic beliefs, and India is the origin of religions such as Hinduism and Buddhism. Thus, the correct answer is indeed Persia, which reflects the true roots of the Bahá'í faith.
