Direct Answer

Scientology developed from L. Ron Hubbard's earlier Dianetics work, published on May 9, 1950. Hubbard's subsequent work on the spiritual side of life became Scientology, and a group of Los Angeles Scientologists formed the first Church in February 1954.

The story begins with Dianetics, opens into Scientology, and then takes organizational form as a Church.

Who was L. Ron Hubbard?

L. Ron Hubbard founded Scientology and wrote Dianetics: The Modern Science of Mental Health. For the history of the religion, his most important role is that the ideas and materials associated with Dianetics and later Scientology began with his work.

Scientology’s early history is a progression from Dianetics to a wider study of the spirit. That distinction matters because the two names still appear side by side in Church books, courses, and services. For a plain-language overview of the religion as it is practiced, see What Is Scientology?.

What is Dianetics and how does it relate to Scientology?

Dianetics: The Modern Science of Mental Health was published on May 9, 1950. The interest that followed led to Dianetics foundations and study groups before Hubbard's later work developed into Scientology.

Dianetics is the earlier subject, and Scientology is the broader religious framework that followed. They are related, but they are not interchangeable labels for exactly the same thing.

That is why an introduction to Scientology can mention Dianetics without treating it as a separate religion. It is part of the historical path into Scientology and remains part of the vocabulary readers encounter today. The practice most often associated with both subjects is explained in What Is Scientology Auditing?.

How did Scientology become organized as a Church?

People studying the new subject formed groups in several countries during the early 1950s. In February 1954, a group of Los Angeles Scientologists formed the first Church of Scientology.

That 1954 milestone marks the moment when a developing subject became an organized Church.

How has the organization evolved since its founding?

The early Church grew from local groups and churches into an international religious organization. By the middle of the following decade, Churches existed in five countries alongside groups in dozens of nations.

Hubbard directly managed early Scientology organizations. He resigned as executive director in 1966 and continued his research and the codification of Scientology materials.

The founding timeline shows where the Church came from; its beliefs, Churches, services, and media show how people meet it today. For a look inside Church locations and members’ stories, see Scientology Documentaries and Series Worth Watching.

Who leads Scientology today?

David Miscavige is the ecclesiastical leader of the Scientology religion.

For readers new to the topic, the practical next step is usually to understand the ideas before trying to absorb the whole timeline. What Are Scientology's Core Beliefs? is a useful companion to this history.
