"law". The Sanskrit word dharma, sometimes translated as religion, also means law. Throughout classical South Asia, the study of law consisted of concepts such as penance through piety and ceremonial as well as practical traditions. Medieval Japan at first had a similar union between imperial law and universal or Buddha law, but these later became independent sources of power. Though traditions, sacred texts, and practices have existed throughout time, most cultures did not align with Western conceptions of religion since they did not separate everyday life from the sacred. In the 18th and 19th centuries, the terms Buddhism, Hinduism, Taoism, Confucianism, and world religions first entered the English language. Native Americans were also thought of as not having religions and also had no word for religion in their languages either. No one self-identified as a Hindu or Buddhist or other similar terms before the 1800s. "Hindu" has historically been used as a geographical, cultural, and later religious identifier for people indigenous to the Indian subcontinent. Throughout its long history, Japan had no concept of religion since there was no corresponding Japanese word, nor anything close to its meaning, but when American warships appeared off the coast of Japan in 1853 and forced the Japanese government to sign treaties demanding, among other things, freedom of religion, the country had to contend with this idea. According to the philologist Max Müller in the 19th century, the root of the English word religion, the Latin , was originally used to mean only reverence for God or the gods, careful pondering of divine things, piety (which Cicero further derived to mean diligence). Müller characterized many other cultures around the world, including Egypt, Persia, and India, as having a similar power structure at this point in history. What is called ancient religion today, they would have only called law. Definition Scholars have failed to agree on a definition of religion. There are, however, two general definition systems: the sociological/functional and the phenomenological/philosophical. Modern Western The concept of religion originated in the modern era in the West. Parallel concepts are not found in many current and past cultures; there is no equivalent term for religion in many languages. Scholars have found it difficult to develop a consistent definition, with some giving up on the possibility of a definition. Others argue that regardless of its definition, it is not appropriate to apply it to non-Western cultures. An
