In 1981, he married Lady Diana Spencer, with whom he had two sons: Prince William and Prince Harry. In 1996, the couple divorced following well-publicised extramarital affairs by both parties.

As the Prince of Wales, Charles undertakes official duties on behalf of the Queen. He founded The Prince's Trust in 1976, sponsors The Prince's Charities, and is a patron, president, or a member of over 400 other charities and organisations. As a self-described environmentalist, Charles has spoken publicly about issues such as organic farming and climate change, which has earned him awards and recognition from environmental groups. His support for alternative medicine, including homeopathy, has been the subject of criticism. His views on the role of architecture in society and the conservation of historic buildings have received significant attention from British architects and design critics. Since 1993, Charles has worked on the creation of Poundbury, an experimental new town based on his architectural tastes. He is also an author or co-author of a number of books.
