Carl Gustav Jung was a Swiss psychiatrist and psychotherapist who introduced the concept of analytical psychology. His Work has dramatically impacted psychiatry, anthropology, archaeology, literature, philosophy, psychology, and religious studies. This interest in the unconscious was already present in Jung's early years of practice and resulted in a close collaboration with Sigmund Freud. Nevertheless, the two split up due to contrasting opinions, especially on the part of sexuality in the development of the psyche. Jung's theories brought new ideas, including the concepts of archetypes, the collective unconscious, and individuation.

Jung was born on March 26, 1875, in Kesswil, Switzerland, to Paul Achilles Jung, a country preacher, and Emilie Preiswerk. Jung's relationship with his mother was somewhat complicated as she suffered from depression; however, he had a very creative childhood. This period can be considered a preparation for his further investigations of the inner world of the human psyche. Jung grew up in a religious family, but his father died when he was young, which made him want to become a doctor and a psychiatrist instead of becoming a clergyman, as the family expected.

Jung's educational pursuits started at the University of Basel, where he initially wanted to do archaeology but had to switch to medicine primarily because he could not afford it. The first stage of his career in the Burghölzli Psychiatric Hospital under the supervision of Eugen Bleuler was crucial. Here, Jung started to formulate his ideas on the unconscious and personality. The dissertation that he submitted was on the psychological aspects of what is referred to as occult practices and signified the start of his career in psychiatry.

Jung married Emma Rauschenbach in 1903, and they had five children. Emma also started to help him with his Work and became his great assistant. The couple's marriage was not without its problems; Jung engaged in extra-marital affairs with his patients, notably Sabina Spielrein and Toni Wolff, but the couple remained married until Emma died Emma's in 1955. Freud and Jung started their collaboration in 1906, but their friendship was ruined in 1912 because of theoretical differences. This break paved the way for the advancement of Jung's concepts on his own.

The middle period of Jung's life was characterized by a deep search for the Jungs and the development of new theories. He had what he referred to as a confrontation with the unconscious and devised the Red Book, in which he documented his inner life. This period was critical to forming his ideas about individuation and the collective unconscious. According to Jung, these processes were innate and present in every society and, therefore, part of human history.

In the First World War, Jung was a doctor in the Swiss army, commanding an internment camp for British officers. After the war, Jung further developed his concepts, wrote extensively, and spread his ideas around the globe. His exposure to Africa, India, and America taught him the different cultural and logical aspects he incorporated into his Work.

The later period of his life was entirely of recognition and scandals. He was awarded many honorary degrees and remained productive in his writing. Even though he made some somewhat questionable comments during the Nazi period and was accused of anti-Semitism, Jung's Jung'sbution to the field of psychology was substantial. He examined the function of spirituality in mental health and argued that the unconscious must be brought into the light for the sake of the individual's growth.

Jung's Work Is extensive, and his theories still resonate in the modern world of psychology, literature, and art. His Work is characterized by the concept of the whole person, where mind, body, and spirit are all interrelated in individuation.
