Simon Sebag Montefiore opens Speeches That Changed the World by establishing his curatorial project: collecting and contextualizing history's most influential speeches, spanning centuries and cultures, while analyzing the specific rhetorical and historical factors that made each genuinely powerful and enduring.

The scope and approach of this curation:

• Montefiore's selection spans an intentionally broad historical and cultural range, from ancient oratory through modern political and social movements, avoiding a narrow focus on any single era, culture, or type of speech
• Each speech is presented with substantial historical context, explaining the specific circumstances and audience that shaped its original delivery and reception, rather than presenting the text in historical isolation
• Montefiore, drawing on his historian's background, pairs this contextual grounding with genuine rhetorical analysis, examining not just what each speech said but how its specific language and delivery techniques contributed to its lasting impact

This dual approach — historical context plus rhetorical analysis — sets up the book's broader project: identifying genuinely transferable principles of persuasive, memorable speech that remain relevant across the dramatically varied historical and cultural contexts represented in the collection.
