Discover when leadership training began. Explore the history of leadership development from ancient mentoring to modern corporate programmes.
Written by Laura Bouttell • Sat 10th January 2026
Leadership training began in earnest as a formal discipline in the 1930s when social scientists started systematically examining leadership behaviours and concluded that leadership is something people do—and therefore something people can learn—though informal leadership development through mentoring, military training, and apprenticeship dates back to ancient civilisations. Modern corporate leadership development programmes emerged primarily in the post-World War II era.
Every organisation today invests in leadership development. Yet few consider where these programmes came from or how our understanding of developing leaders has evolved. The history of leadership training reveals important insights about what works and why—lessons that inform better programme design today.
This guide traces leadership training from ancient practices through theoretical evolution to contemporary approaches, illuminating how we arrived at modern leadership development and where it may be heading.
Leadership development predates formal training programmes.
Ancient armies recognised that effective leadership required development:
Ancient military development:
| Civilisation | Development Approach |
|---|---|
| Spartan | Agoge youth training system |
| Roman | Cursus honorum progression |
| Chinese | Sun Tzu strategic education |
| Greek | Military academies |
| Medieval | Knighthood preparation |
The oldest form of leadership development:
Traditional development methods:
Ancient philosophers addressed leadership development:
Philosophical contributions:
When leadership became a research subject.
"Back in the 1930s, social scientists began to examine leadership. Through these studies, it was determined that leadership is something people do, and therefore the premise was developed that it is possibly something that people can learn to do."
Significance of 1930s research:
Prior to scientific study, leadership was considered innate:
Great Man perspective:
The behavioural turn enabled training:
"In the early 20th century, another leadership theory emerged related to Behavior, which suggested that effective leadership could be learned through observation and practice rather than inherent, at birth, qualities."
Behavioural implications:
How theory shaped training approaches.
Leadership development transitioned through distinct phases:
Theoretical evolution:
| Era | Theory | Training Implication |
|---|---|---|
| Pre-1930s | Great Man | Selection over development |
| 1930s-1940s | Trait theories | Identifying leadership qualities |
| 1940s-1960s | Behavioural theories | Teaching specific behaviours |
| 1960s-1980s | Contingency theories | Situational adaptation |
| 1978+ | Transformational | Inspiring vision and change |
| 1990s+ | Emotional Intelligence | Self-awareness and empathy |
Landmark research that shaped training:
Study contributions:
"During World War II, the study of leadership shifted again to a more situational approach, which recognized that effective leadership depended on the specific circumstances and context of a given situation."
Situational implications:
The war transformed leadership training.
WWII accelerated leadership development:
Wartime developments:
"The earliest history of training and development and organization development (OD) is rooted in the origins of education itself, showing a continuum from survival-driven learning to the post–World War II era leadership development programs."
Corporate adoption:
Post-war developments established patterns:
Modern training foundations:
Key developments that shaped the field.
"In 1978, James MacGregor Burns introduced the idea of transformational leadership as he researched political leaders."

Today's leadership development typically includes:
Modern components:
| Component | Purpose |
|---|---|
| Assessment | Understanding current capability |
| Classroom learning | Concept and framework introduction |
| Experiential exercises | Practice in safe environment |
| Coaching | Personalised guidance |
| Action learning | Real-world application |
| Feedback | Continuous improvement |

Formal leadership training began in the 1930s when social scientists started systematically studying leadership and concluded it could be learned. However, informal development through military training, mentoring, and philosophical education dates back to ancient civilisations. Modern corporate leadership development programmes emerged primarily after World War II.
The earliest formal leadership theory was the "Great Man" theory from the 19th century, which argued leaders were born with innate greatness. Scientific study began in the 1930s with trait theories, followed by behavioural approaches in the 1940s-1960s, contingency theories in the 1960s-1980s, and transformational leadership from 1978 onwards.
World War II dramatically accelerated leadership development through rapid officer training programmes, assessment centre methods, and large-scale development operations. After the war, veterans brought military approaches to corporations, leading to systematic business leadership programmes. Many modern training methods originated during this period.
James MacGregor Burns introduced transformational leadership in 1978 whilst researching political leaders. Burns theorised that transformational leadership involves leaders and followers inspiring each other to advance together. Bernard Bass later expanded the theory for organisational application, significantly influencing modern leadership development programmes.
Leadership training evolved from emphasis on innate traits to behavioural skill development, then to situational adaptation, and finally to transformational and emotionally intelligent approaches. Modern programmes combine assessment, classroom learning, experiential exercises, coaching, and action learning, informed by research on what actually develops leadership capability.
Effective leadership training combines multiple approaches (blended learning), includes practice opportunities with feedback, connects to real work challenges, provides ongoing support and coaching, and integrates with organisational systems. Research shows leaders who practice and receive feedback during training apply 25% more learning on the job.
Leadership development as a formal discipline is relatively recent, emerging in the 20th century. However, developing leaders through mentoring, military training, philosophical education, and experiential learning dates back thousands of years. Ancient civilisations like Sparta, Rome, and China all had systematic approaches to preparing leaders.
