Historians play a crucial role in the development of their country because they analyze past events and government strategies, allowing society to learn from successes and mistakes. By studying historical patterns, they provide insights that help shape better policies, promote cultural identity, and guide future decision-making.

One example is Arnold Toynbee, a British historian who analyzed the rise and fall of civilizations. His work influenced policymakers by highlighting how societies that fail to adapt to challenges decline, while those that innovate thrive. His insights were used in post-World War II reconstruction efforts, helping nations like the UK and the US shape economic and social policies for long-term stability.
