Zarathustra, also known as Zoroaster, is the founder of Zoroastrianism, one of the world's oldest monotheistic religions. He is believed to have lived in ancient Persia, likely around the 6th century BCE, and his teachings emphasized the duality of good and evil, the importance of individual choice, and the worship of one supreme god, Ahura Mazda. His philosophical ideas laid the groundwork for many concepts in later religious traditions.
