This weekend, the United States marks 250 years since the adoption of the Declaration of Independence, one of the most influential political texts in modern history. Its assertion that governments derive their power from the consent of the governed, and that all people are endowed with the rights to life, liberty and the pursuit of happiness, has inspired democratic movements around the world.

As every year, the Fourth of July is celebrated with parades, fireworks, family barbecues and community gatherings across the country. Hot dogs, corn on the cob and watermelon remain staples of the holiday, while military flyovers and patriotic ceremonies form part of the official commemorations. In Washington, festivities are taking place despite an intense heatwave affecting much of the eastern United States. This anniversary carries particular significance, coming at a time of deep political divisions and heightened debate over the country's identity and future. Fireworks lit up the skies over Mount Rushmore, illuminating the faces of Presidents George Washington, Thomas Jefferson, Abraham Lincoln and Theodore Roosevelt, as celebrations got underway. President Donald Trump officially launched the anniversary events, using his address to warn of what he described as ideological threats facing the United States, while reaffirming his vision of American exceptionalism. Elsewhere, another American whose voice carries global influence, Pope Leo, marked the anniversary from the Italian island of Lampedusa. In a message focused on migration, compassion and solidarity, he also reflected on the values the United States was founded upon 250 years ago. In New York, Mayor Zoran Mamdani, himself the son of immigrants, delivered his own address, offering a different perspective on the American story and the country's future. To discuss the legacy of the Declaration of Independence, the significance of this 250th anniversary, and what it says about America today, I'm joined in the studio by Curtis Young, American-born historian and Professor of Literature at ESSEC Business School.
