Silver Jubilee of Elizabeth II

The Silver Jubilee of Elizabeth II marked the 25th anniversary of Queen Elizabeth II's accession to the thrones of the United Kingdom and other Commonwealth realms. It was celebrated with large-scale parties and parades throughout the United Kingdom and the Commonwealth throughout 1977, culminating in June with the official "Jubilee Days," held to coincide with the Queen's Official Birthday. The anniversary date itself was commemorated in church services across the land on 6 February 1977, and continued throughout the month. In March, preparations started for large parties in every major city of the United Kingdom, as well as for smaller ones for countless individual streets throughout the country.

No monarch before Queen Elizabeth II had visited more of the United Kingdom in such a short span of time (the trips lasted three months). All in all, the Queen and her husband Prince Philip visited a total of 36 counties. The trip started with record crowds gathering to see the Queen and Prince Philip in Glasgow on 17 May. After moving to England (where a record one million spectators came to greet the couple in Lancashire) and Wales, the Queen and Prince Philip wrapped up the first of their trips with a visit to Northern Ireland. Among the places visited during the national trips were numerous schools, which were the subject of a television special hosted by presenter Valerie Singleton.

Later in the summer, the Queen and Prince Philip embarked on a Commonwealth visit that first brought them to island nations such as Fiji and Tonga, following up with longer stints in New Zealand and Australia, with a final stop in Papua New Guinea before going on to the British holdings in the West Indies. The final stop on the international tour was a trip to Canada, in which Prince Charles joined the couple to greet the crowds.
