Exorcism, the practice of expelling demons or evil spirits from a person or place, is a long-standing method practiced in various cultures and religions around the world. In recent years, however, modern exorcism has experienced a renaissance and has become a controversial and divisive topic.

In modern times, exorcism is often performed by Catholic clergy or priests who believe that a person can be possessed by demons. The practice has also played a role in other Christian communities such as the Protestant and Evangelical churches and even in non-Christian faiths such as Islam and Hinduism.

An important factor in the revival of modern exorcism is the increasing popularity of horror films and series, which have brought the subject into the public eye. Films such as "The Exorcist" (1973) and "The Exorcism Experiment" (2011) have sparked interest in the practice and have helped modern exorcism become a topic that is discussed more.

Modern society has also changed, and many people feel frightened and vulnerable by the growing uncertainty and instability in the world. Exorcism offers a kind of spiritual healing and insurance against the dangers of the world.

There is also a growing perception that mental disorders that have been seen as possession in the past may actually have medical causes. .
