On April 28, 2026, King Charles III will address a joint session of the U.S. Congress, affirming the historic ties and collaborative spirit between the United Kingdom and the United States. This address, taking place during his four-day state visit to the U.S., underscores the importance of their "special relationship," particularly as the U.S. marks its 250th anniversary of independence from Britain.

King Charles will highlight the notion that, despite varying challenges and political disagreements, "time and again, our two countries have always found ways to come together." His words are notably poignant given the current strain in U.S.-U.K. relations over the conflict in Iran. The king is expected to emphasize shared democratic values, military alliances, and the significance of historical ties that date back to events like the Magna Carta.

In light of recent tensions, particularly regarding the U.S. war in Iran and criticisms aimed at British Prime Minister Keir Starmer, King Charles aims to steer the conversation towards reconciliation and the continued friendship between the two nations. He is also known to incorporate personal elements into his speeches, reflecting his beliefs about compassion and mutual understanding among diverse communities.

The address, lasting approximately 20 minutes, will be one of the most significant public statements of his reign. This marks only the second time in history that a British monarch has spoken before Congress, with Queen Elizabeth II being the first in 1991.

Following his congressional speech, King Charles will participate in a state dinner hosted by President Donald Trump, further underlining the ceremonial importance of this visit. The king’s ability to navigate political sensitivities while promoting the longstanding alliance between the U.S. and U.K. speaks to his role in fostering international relationships through soft power.

As the day unfolds, Charles and Queen Camilla will continue to engage with officials and citizens, culminating in a series of events designed to honor the enduring partnership between the two nations amidst a backdrop of both historic celebration and contemporary challenges.
