William IV in the context of "George III"

Adelaide (/ˈædɪleɪd/ AD-il-ayd; Kaurna: Tarndanya [ˈd̪̥aɳɖaɲa]) is the capital and most populous city of South Australia, as well as the fifth-most populous city in Australia. The name "Adelaide" may refer to either Greater Adelaide (including the Adelaide Hills) or the Adelaide city centre; the demonym Adelaidean is used to denote the city and the residents of Adelaide. The traditional owners of the Adelaide region are the Kaurna, with the name Tarndanya referring to the area of the city centre and surrounding Park Lands, in the Kaurna language. Adelaide is situated on the Adelaide Plains north of the Fleurieu Peninsula, between the Gulf St Vincent in the west and the Mount Lofty Ranges in the east. Its metropolitan area encompasses over 430 suburbs, extending 96 km (60 mi) from Gawler in the north to Sellicks Beach in the south and 20 km (12 mi) from the western coast to the eastern foothills of the Mount Lofty Ranges.

Named in honour of Adelaide of Saxe-Meiningen, wife of King William IV, the city was founded in 1836 as the planned capital for the only freely settled British province in Australia, distinguishing it from Australia's penal colonies. Colonel William Light, one of Adelaide's founding fathers, designed the city centre and chose its location close to the River Torrens. Light's design, now listed as national heritage, set out the city centre in a grid layout known as "Light's Vision", interspaced by wide boulevards and large public squares, and entirely surrounded by park lands. Colonial Adelaide was noted for its leading examples of religious freedom and progressive political reforms and became known as the "City of Churches" due to its diversity of faiths. It was Australia's third-most populous city until the postwar era.

The Regency era of British history is commonly understood as the years between c. 1795 and 1837, although the official regency for which it is named only spanned the years 1811 to 1820. King George III first suffered debilitating illness in the late 1780s, and relapsed into his final mental illness in 1810. By the Regency Act 1811, his eldest son George, Prince of Wales, was appointed Prince Regent to discharge royal functions. The Prince had been a major force in Society for decades. When George III died in 1820, the Prince Regent succeeded him as George IV. In terms of periodisation, the longer timespan is roughly the final third of the Georgian era (1714–1837), encompassing the last 25 years or so of George III's reign, including the official Regency, and the complete reigns of both George IV and his brother and successor William IV. It ends with the accession of Queen Victoria in June 1837 and is followed by the Victorian era (1837–1901).

Although the Regency era is remembered as a time of refinement and culture, that was the preserve of the wealthy few, especially those in the Prince Regent's own social circle. For the masses, poverty was rampant as urban population density rose due to industrial labour migration. City dwellers lived in increasingly larger slums, a state of affairs severely aggravated by the combined impact of war, economic collapse, mass unemployment, a bad harvest in 1816 (the "Year Without a Summer"), and an ongoing population boom. Political response to the crisis included the Corn Laws, the Peterloo Massacre, and the Representation of the People Act 1832. Led by William Wilberforce, there was increasing support for the abolitionist cause during the Regency era, culminating in passage of the Slave Trade Act 1807 and the Slavery Abolition Act 1833.

The Georgian era was a period in British history from 1714 to 1837, named after the Hanoverian kings George I, George II, George III and George IV. The definition of the Georgian era is also often extended to include the relatively short reign of William IV, which ended with his death in 1837. The subperiod that is the Regency era is defined by the regency of George IV as Prince of Wales during the illness of his father George III. The term Georgian is typically used in the contexts of social and political history and architecture. The term Augustan literature is often used for Augustan drama, Augustan poetry and Augustan prose in the period 1700–1740s. The term Augustan refers to the acknowledgement of the influence of Latin literature from the ancient Roman Republic. The term Georgian era is not applied to the time of the two 20th-century British kings of this name, George V and George VI. Those periods are simply referred to as Georgian.

When Victoria became Queen in 1837 the Georgian era was followed by the Victorian era. The Victorians emphasized moral earnestness and propriety, as well as industrial and scientific progress and scientific advancement. There was a growing tension between faith and doubt and more Realism in literature and art (moving away from Romantic idealism).

The Representation of the People Act 1832 (also known as the Reform Act 1832, Great Reform Act or First Reform Act) was an act of the Parliament of the United Kingdom (indexed as 2 & 3 Will. 4. c. 45) to reform the electoral system in England and Wales and to expand the franchise. The measure was brought forward by the Whig government of Prime Minister Charles Grey, 2nd Earl Grey.

The legislation granted the right to vote to a broader segment of the male population by standardizing property qualifications, extending the franchise to small landowners, tenant farmers, shopkeepers, and all householders who paid a yearly rental of £10 or more. The act also reapportioned constituencies to address the unequal distribution of seats. The act of England and Wales was accompanied by the Scottish Reform Act 1832 (2 & 3 Will. 4. c. 65) and Irish Reform Act 1832 (2 & 3 Will. 4. c. 88).

Dorothea Jordan (née Bland; 22 November 1761 – 5 July 1816) was an Anglo-Irish actress, as well as a courtesan. She was the long-time partner of Prince William, Duke of Clarence (later King William IV), and the mother of 10 illegitimate children by him, all of whom took the surname FitzClarence. She was known professionally as Dorothea Francis and Dorothea Jordan, was informally Dora Jordan, and she was commonly referred to as Mrs Jordan and Mrs FitzClarence.

King William Street is the part of a major arterial road that traverses the CBD and centre of Adelaide, continuing as King William Road to the north of North Terrace and south of Greenhill Road; between South Terrace and Greenhill Road it is called Peacock Road. At approximately 40 metres (130 ft) wide, King William Street is the widest main street of all the Australian state capital cities. Named after King William IV in 1837, it is historically considered one of Adelaide's high streets, for its focal point of businesses, shops and other prominent establishments. The Glenelg tram line runs along the middle of the street through the city centre.
