The school was founded in 1898 upon an initiative by the Leipzig Chamber of Commerce. In 1946, it was integrated into Leipzig University and regained partial independence in 1969.

The doctoral program is for candidates who hold a secondary university degree. Within three years, the candidate participates in lectures, courses, a research colloquium and conferences. After successfully completing all requirements and acceptance of the doctoral thesis, the candidate is awarded the degree Dr. rer.oec.

The Leipzig Leadership Model (LLM) is an interdisciplinary and multidimensional framework for good leadership developed at HHL Leipzig Graduate School of Management in 2016. The LLM uses its four dimensions (purpose, entrepreneurial spirit, effectiveness and responsibility) to link important questions of meaning and values with the strategic and operational tasks of entrepreneurial activity. The four dimensions can be applied using key questions and guide reflection:

- Are we pursuing an overarching goal? (Purpose)

- Do we think and act entrepreneurially? (entrepreneurial spirit)

- Are our actions legitimate? (Responsibility)

- Are we effective? (Effectiveness)
