Bahá'u'lláh, the Prophet-Founder of the Bahá'í Faith, proclaimed the oneness of humankind the central principle and goal of His Faith, implying the organic and spiritual unity of the whole body of nations and signaling the coming of age of the entire human race. Bahá'u'lláh's expressed purpose was to usher in the next stage in humanity’s development, namely, world unity and the Great Peace foretold in the sacred scriptures of the world's religions.
