'God Save the King" is the national anthem of the United Kingdom. The anthem's lyrical origins can be traced back to the early 18th century, and it has undergone various modifications over time. The original anthem, known as "God Save great George our King," was first publicly performed in London in 1745 during the last Jacobite rebellion.

Throughout World War I, "God Save the King" remained a symbol of British resilience and unity, serving as a constant reminder of the values for which the nation was fighting. Its stirring melodies and lyrics helped to instil a sense of pride and purpose among both civilians and soldiers during one of the most challenging periods in British history.
