Historical Context

Key Lessons
Margaret's greatest strength (Iron will and Ideological conviction) was also their greatest liability when taken to extremes.
The The Ruler archetype tends to succeed in environments that reward bold action and long-term vision, but struggles in environments that demand consensus-building.
