King Charles III marks 250th anniversary of the United States

On July 4, 2026, King Charles III issued a personal message to mark the 250th anniversary of the United States Declaration of Independence. Signed 'Charles R', the message emphasized the historical ties between London and Washington, founded on shared values such as the rule of law and human dignity. The monarch expressed confidence that the bilateral relationship would continue to strengthen over the next 250 years. This communication follows a four-day official visit by King Charles to the United States in late April. During that visit, President Donald Trump reaffirmed the status of the United Kingdom as a primary ally, highlighting 'blood' ties between the nations. Trump’s remarks avoided addressing past diplomatic frictions related to the conflict in Iran. The message was disseminated via the official Royal Family social media account on X. The use of the Latin signature indicates a personal statement from the sovereign rather than a formal announcement from Buckingham Palace.
