In 1863, Baha'u'llah declared his mission, founding the Baha'i Faith and promoting the unity of all religions. This new religious movement emphasized principles such as the oneness of humanity, equality, and the importance of global peace. Baha'u'llah's teachings have since inspired millions around the world, fostering interfaith dialogue and social justice initiatives, and continue to influence contemporary discussions on spirituality and community.

The founding of the Baha'i Faith by Baha'u'llah in 1863 introduced universalist themes that significantly influenced 20th-century interfaith poetry. Poets such as Rumi and contemporary writers began to explore concepts of unity, peace, and the interconnectedness of humanity in their works.
