Religion is a term used to describe belief in the existence of spiritual beings and the practice of praising or worshiping them. It is believed that every culture throughout history has had some form of religion. The belief in a supreme being, afterlife, and forgiveness are usually central to religion. Other beliefs and practices include prayers, sermons, trance-like conditions, sacraments, initiation ceremonies, matrimonial and funerary rituals, meditation, art, music, dance, public service, and so on. It is possible for some people to believe in multiple religions at the same time.

The concept of religion has always been a complex one. Some scholars have treated it as a universal phenomenon, while others have focused on describing specific religions. There is a growing movement, however, to define religion more broadly. This “functionalist” approach to religion emphasizes the role that it plays in human societies. It views religion as a system of values that gives meaning and purpose to life, reinforces social cohesion and stability, serves as a mechanism for the control of behavior, promotes psychological and physical well-being, and may motivate individuals to work for positive social change.

Anthropologists generally agree that religion developed early in pre-historic times as a way to deal with uncontrollable parts of the environment, such as weather, pregnancy and birth, and hunting success. Early religions tried to manipulate the environment directly through magic, or they supplicated to higher powers, gods and goddesses, for help in controlling it.

Religious experiences are important to many people and can be profoundly moving. These experiences can involve crying, laughing, screaming, trancelike states, and a feeling of oneness with others. Religious rites and ceremonies can also be intense, often involving deep emotion and a sense of transcendence. They can be a source of inspiration for creativity, such as poetry and music or a source of moral strength, such as devotion to a saint or guru.

While some people identify with a particular religion, many are religious “nones,” meaning they do not belong to any particular religion. These people may still believe in a God, or they may regard themselves as spiritual but not religious. Among the religiously unaffiliated, some believe in an impersonal God or in a cosmic force such as love or nature. Others believe that humanity is on a journey toward spirituality and that we are discovering a universe of spirits that already exists.

The word religion derives from the Latin Relegere or religio, meaning a devotion to sacred things, a respect for what is holy. In the modern world, we see evidence of a continuing religious influence in areas such as fashion and media, war, colonization and enslavement, abolition and legislation, marriage practices, and education. Religion has influenced astronomy, ecology, and other fields of study. It has influenced, and continues to influence, the political system in most countries around the world. It is a powerful part of our global culture and an essential element in the lives of billions of people.
