King George IV in the context of "Caroline of Brunswick"

The Royal Marines provide the United Kingdom's amphibious special operations capable commando force, one of the five fighting arms of the Royal Navy, a company strength sub-unit to the Special Forces Support Group (SFSG), landing craft crews, and the Naval Service's military bands. The Royal Marines trace their origins back to the formation of the "Duke of York and Albany's maritime regiment of Foot" on 28 October 1664, and the first Royal Marines Commando unit was formed at Deal in Kent on 14 February 1942 and designated "The Royal Marine Commando".

The Royal Marines have seen action across many conflicts but do not have battle honours as such, but rather the "Great Globe itself" was chosen in 1827 by King George IV in their place to recognise the Marines' service and successes in multiple engagements in every quarter of the world. Today it consists of the United Kingdom Commando Force, the Royal Marines Band Service, the Commando Training Centre and four Reserve Units.

Chinoiserie (English: /ʃɪnˈwɑːzəri/, French: [ʃinwazʁi] ; loanword from French chinoiserie, from chinois, "Chinese"; traditional Chinese: 中國風; simplified Chinese: 中国风; pinyin: Zhōngguófēng; lit. 'China style') is the European interpretation and imitation of Chinese and other Sinosphere artistic traditions, especially in the decorative arts, garden design, architecture, literature, theatre, and music. The aesthetic of chinoiserie has been expressed in different ways depending on the region. It is related to the broader current of Orientalism, which studied Far East cultures from a historical, philological, anthropological, philosophical, and religious point of view. First appearing in the 17th century, this trend was popularized in the 18th century due to the rise in trade with China (during the High Qing era) and the rest of East Asia.

As a style, chinoiserie is related to the Rococo style. Both styles are characterized by exuberant decoration, asymmetry, a focus on materials, and stylized nature and subject matter that focuses on leisure and pleasure. Chinoiserie focuses on subjects that were thought by Europeans to be typical of Chinese culture.

The Pains and Penalties Bill 1820 was a bill introduced to the British Parliament in 1820, at the request of King George IV, which aimed to dissolve his marriage to Caroline of Brunswick, and deprive her of the title of queen.

George and Caroline had married in 1795, when George was still Prince of Wales. After the birth of their only child, Princess Charlotte of Wales, they separated. Caroline eventually went to live abroad, where she appointed Bartolomeo Pergami to her household as a courier. He eventually rose to become the head servant of her household, and it was widely rumoured that they were lovers.

The Roman Catholic Relief Act 1829 (10 Geo. 4. c. 7), also known as the Catholic Emancipation Act 1829, was an act of the Parliament of the United Kingdom that removed the sacramental tests that barred Roman Catholics in the United Kingdom of Great Britain and Ireland from Parliament and from higher offices of the judiciary and state. It was the high point of a fifty-year process of Catholic emancipation which had offered Catholics successive measures of "relief" from the anti-Catholic civil and political disabilities imposed by Penal Laws in both the Kingdom of Great Britain and the Kingdom of Ireland in the seventeenth and early eighteenth centuries.

Convinced that the measure was essential to maintain order in Catholic-majority Ireland, the Prime Minister, the Duke of Wellington, helped to overcome the opposition of King George IV and the House of Lords by threatening to resign and retire the Tory government he led in favour of a new, reform-minded Whig ministry.

Hongi Hika (c. 1772 – 6 March 1828) was a New Zealand Māori rangatira (chief) and war leader of the iwi of Ngāpuhi. He was a pivotal figure in the early years of regular European contact and settlement in New Zealand. As one of the first Māori leaders to understand the advantages of European muskets in warfare, he used them to overrun much of northern New Zealand in the early nineteenth century Musket Wars.

In order to obtain the muskets Hongi Hika encouraged Pākehā (European) settlement, built mutually beneficial relationships with New Zealand's first missionaries, introduced Māori to Western agriculture and helped put the Māori language into writing. He traveled to England and met King George IV. His military campaigns resulted in the Musket Wars, and preventing them was an important motivators for the British annexation of New Zealand and subsequent Treaty of Waitangi with Ngāpuhi and many other iwi.
