Bahá'u'lláh was the founder of the Bahá'í Faith, a religion that emerged in the 19th century. Born in 1817 in Persia (modern-day Iran), he claimed to be the latest in a line of prophets that includes Moses, Jesus, and Muhammad. His teachings emphasize the unity of all people and religions, advocating for peace, justice, and equality. In 1863, Bahá'u'lláh declared his mission in the garden of Ridván, marking the beginning of the Bahá'í Faith. He wrote numerous texts, including the Kitáb-i-Aqdas, which outlines the principles and laws of the religion. Bahá'u'lláh passed away in 1892, leaving a legacy that continues to inspire millions worldwide.
