George Frideric (or Frederick) Handel (1685 – 1759 ) was a German-British Baroque composer well known for his operas, oratorios, anthems, concerti grossi, and organ concertos. Handel received his training in Halle and worked as a composer in Hamburg and Italy before settling in London in 1712, where he spent the bulk of his career and became a naturalised British subject in 1727. He was strongly influenced both by the middle-German polyphonic choral tradition and by composers of the Italian Baroque. In turn, Handel's music forms one of the peaks of the "high baroque" style, bringing Italian opera to its highest development, creating the genres of English oratorio and organ concerto, and introducing a new style into English church music. He is consistently recognized as one of the greatest composers of his age.

Although part of the traditional content of British coronations, the texts for all four anthems were picked by Handel—a personal selection from the most accessible account of an earlier coronation, that of James II of England in 1685. One of George I of Great Britain's last acts before his death in 1727 was to sign an "Act of naturalisation of George Frideric Händel and others". Handel's first commission as a newly naturalised British subject was to write the music for the coronation of George II of Great Britain and Queen Caroline which took place on 11 October the same year. Within the coronation ceremonies Let thy hand be strengthened was played first, then Zadok, then The King shall rejoice, and finally My heart is inditing at the coronation of the Queen. (In modern coronations the order is Zadok, Let thy hand be strengthened, The King shall rejoice and My heart is inditing, with the order of Let thy hand be strengthened and The King shall rejoice sometimes reversed.)

Right from their composition the four anthems have been popular and regularly played in concerts and festivals even during Handel's own lifetime. He re-used substantial extracts from them in many of his oratorios without many changes (other than to the text), notably Esther and Deborah. Two of the anthems were played at the 1742 inauguration of the Holywell Music Room in Oxford, a hall dedicated to chamber music. Their success perhaps contributed to the popular image of Handel as a composer whose music required a huge number of singers and musicians (the more the better)—in other words, the character criticised by Berlioz as "a barrel of pork and beer". In practice, Handel often adapted his music to the occasion and to the skill of those for whom he was writing, and no occasion could be grander than a coronation. The ceremonial style of the anthems differs from his music for the theatre just as his Music for the Royal Fireworks (the latter designed for open-air performance) differs from his instrumental concertos. The anthems show a completely extrovert tone, managing massed forces and important contrasts rather than delicate colours—with the wide spatial reverberation in Westminster Abbey, he did not waste time and effort trying to show small points of detail.

The means he had at his disposal were the most important of the era—the choir of the Chapel Royal was augmented by 47 singers, with an orchestra which reached perhaps 160 people. The chorus was divided into 6 or 7 groups (with the tenors kept together) and a large string section, made up of three groups of violins (rather than the two which were usual).

"Zadok the Priest" (HWV 258) is thought to have been composed between 9 September and 11 October 1727.
"Let Thy Hand Be Strengthened" (HWV 259) is thought to have been composed between 9 September 1727 and 11 October 1727.
"The King Shall Rejoice" (HWV 260) is thought to have been composed between 9 September 1727 and 11 October 1727.
"My Heart is Inditing" (HWV 261) is thought to have been composed between 9 September 1727 and 11 October 1727.
