Who gave the call return to the Vedas?

The call to return to the Vedas was notably championed by Swami Dayananda Saraswati, the founder of the Arya Samaj in the late 19th century. He emphasized the importance of the Vedas as the foundational texts of Hinduism and advocated for a reform movement that aimed to revive Vedic principles and practices. His teachings encouraged a return to the original spiritual and philosophical teachings found in the Vedas, promoting rationalism and social reform.
