A google search with ["leadership theories"] (exact words) should return around 700 000 entries .
Based on our academic litterature research , we have designed a table featuring 10 leadership theories.
The theories have been listed in chronological order and each theory is described with
- a most concurred name
- the approximative period when the theory is said to have emerged
- a definition in less than 10 words
- an emblematic author, a minimal quote
- one or two seminal works.
Some of these reference works may be freely accessible via the open web and we have possibly placed a direct link.
The authors featured in the table are most often quoted in academic papers, articles or posts on professional blogs.
We have included into the table William Moulton Marston though his work does not explicitly address a leadership theory : the reading of his book, "Emotions of normal people", 1928, in its original version, was precious to our creating the DISC Governance pattern .
