The Power of Words: How Letters Spark Change and Shape History

Throughout history, powerful letters have driven monumental change—uniting people, challenging injustice, and sparking movements. From political leaders to everyday citizens, the art of persuasive writing has been a tool for those demanding justice, equity, and compassion.

In this article, we’ll delve into how letters from two iconic figures—Nelson Mandela and Marcus Rashford—demonstrated the transformative power of the written word. We’ll explore what made these letters impactful, why they resonated so deeply, and how you can write with similar conviction to effect change.

Nelson Mandela: Writing for Justice and Freedom

Nelson Mandela’s journey from prisoner to President of South Africa is a testament to the power of resilience, courage, and the written word. During his 27 years in prison, Mandela wrote letters that carried hope, strength, and a relentless commitment to justice—messages that transcended prison walls and inspired a global movement.

Letters from Prison: Words That Shook a Nation

While confined in Robben Island Prison, Mandela’s letters to his family, political allies, and the public were filled with determination and conviction. He used his words to denounce apartheid, promote peace, and call for justice. These letters were a lifeline for a nation yearning for freedom and equality.

In a 1976 letter to his wife, Winnie Mandela, he wrote:

"Difficulties break some men but make others. No axe is sharp enough to cut the soul of a sinner who keeps on trying, one armed with the hope that he will rise even in the end."

His words, filled with unshakeable resolve, spread throughout South Africa and the world, rallying support against apartheid. Mandela’s letters exemplify the power of a persuasive, impassioned voice—proof that even from behind bars, words can dismantle oppression.

Marcus Rashford: A Letter That Changed Government Policy

In 2020, Manchester United and England footballer Marcus Rashford proved that letters are still a powerful tool for change. Using his platform, Rashford took on the UK government’s decision to end free school meal vouchers during the summer holidays—an action that would leave millions of vulnerable children without meals.

An Open Letter That Stirred a Nation

Rashford’s open letter was personal, emotional, and authentic. He shared his own experiences growing up in poverty, relying on breakfast clubs, free school meals, and the kindness of neighbours. In his heartfelt plea, Rashford emphasised:

“This is not about politics; this is about humanity. Can we not all agree that no child should be going to bed hungry?”

His powerful message resonated with the British public, media, and political figures alike. The government ultimately reversed its decision, announcing a £120 million Covid summer food fund, providing meals to 1.3 million vulnerable children in England.

Rashford’s approach shows the importance of speaking from personal experience—he humanised an issue, making it relatable and urgent. His words were backed by compassion, credibility, and a compelling narrative.

What Makes These Letters So Powerful?

Both Mandela and Rashford used letters as a force for change. Their letters shared key qualities:

1. Authenticity and Vulnerability: They shared personal stories, making their messages relatable.

2. Emotional Appeal: They connected deeply, stirring compassion and urgency.

3. A Call to Action: Each letter clearly stated what needed to change.

4. Authority and Credibility: They spoke from a place of experience and knowledge.

5. Empathy and Humanity: They focused on the impact of injustice on real people.

These elements are critical when writing letters that aim to inspire action.

How to Write a Persuasive Letter That Drives Change

Writing a persuasive letter, whether for social change or personal requests, can be powerful if done right. Here’s a step-by-step guide:

1. Define Your Purpose Clearly

Start by outlining your goal. What do you want the reader to do, change, or acknowledge? Be specific and concise.

✅ Example: “I am writing to request a review of the current policy on free school meals, which is leaving thousands of children hungry.”

2. Appeal to Emotions with Personal Stories

Personal stories connect with readers on a human level. Share an experience that illustrates the problem.

✅ Example: “Growing up, I relied on school meals to get by—my story is not unique. Thousands of children face the same struggle every day.”

3. Present Facts and Evidence

Support your argument with credible data and sources. Well-researched points establish authority and trust.

4. Acknowledge Opposing Views and Counter Them

Strengthen your position by addressing opposing arguments.

✅ Example: “While I understand that funding is limited, investing in children’s health and education yields long-term benefits for society.”

5. Create a Compelling Call to Action

End your letter with a clear request and a deadline if appropriate.

✅ Example: “I urge you to reconsider this policy before the summer holidays begin. Children cannot wait.”
