Factional rivalries; the emergence of Henry Tudor, dissensions among the Yorkist nobility, Buckingham's rebellion
After Richard III seized the throne in 1483, powerful nobles turned against him. Their quarrels and betrayals gave Henry Tudor — a rival claimant — the opening he needed to challenge for the crown.
Real World
Buckingham switching from Richard's chief supporter to leading a rebellion within months mirrors the rapid political betrayals seen in the fall of Stalin's close ally Beria in 1953 — proximity to power can become its own fatal liability when the regime looks vulnerable.
Exam Focus
When explaining Henry Tudor's rise, always connect it to Yorkist divisions — his success depended on his opponents' weakness as much as his own strength.
