Union Flag in the context of "Saint Patrick's Saltire"

The image of Britannia (/brɪˈtæniə/) is the national personification of Britain as a helmeted female warrior holding a trident and shield. An image first used by the Romans in classical antiquity, the Latin Britannia was the name variously applied to the British Isles, Great Britain, and the Roman province of Britain during the Roman Empire. The Roman Britannia was typically depicted reclining or seated, with not a trident but a spear and shield, appearing on Roman coins of the 2nd century AD. The classical allegory was revived in the early modern period. On coins of the pound sterling issued by Charles II of England, Scotland, and Ireland, Britannia appears with her shield bearing the Union Flag. To symbolise the Royal Navy's victories, Britannia's spear became the trident in 1797, and a helmet was added to the coinage in 1825.

By the 1st century BC, Britannia had replaced Albion as the prevalent Latin name for the island of Great Britain. After the Roman conquest in 43 AD, Britannia came to refer to the Roman province that encompassed the southern two-thirds of the island (see Roman Britain). The remaining third of the island, known to the Romans as Caledonia, lay north of the River Forth in modern Scotland. It was intermittently but not permanently occupied by the Roman army. The name is a Latinisation of the native Brittonic word for Great Britain, Pretanī, which also produced the Greek form Prettanike or Brettaniai.

Ulster loyalism is a strand of Ulster unionism associated with working class Ulster Protestants in Northern Ireland. Like other unionists, loyalists support the continued existence of Northern Ireland (and formerly all of Ireland) within the United Kingdom, and oppose a united Ireland independent of the UK. Unlike other strands of unionism, loyalism has been described as an ethnic nationalism of Ulster Protestants and "a variation of British nationalism". Loyalists are often said to have a conditional loyalty to the British state so long as it defends their interests. They see themselves as loyal primarily to the Protestant British monarchy rather than to British governments and institutions, while Garret FitzGerald argued they are loyal to 'Ulster' over 'the Union'. A small minority of loyalists have called for an independent Ulster Protestant state, believing they cannot rely on British governments to support them (see Ulster nationalism). The term 'loyalism' is usually associated with paramilitarism.

Ulster loyalism emerged in the late 19th century, in reaction to the Irish Home Rule movement and the rise of Irish nationalism. Ireland had a Catholic majority who wanted self-government, but the province of Ulster had a Protestant and unionist majority, largely due to the Plantation of Ulster. Although not all unionists were Protestant, loyalists emphasised their British Protestant heritage. During the Home Rule Crisis (1912–14), loyalists founded the paramilitary Ulster Volunteers to prevent Ulster from becoming part of a self-governing Ireland. This was followed by the Irish War of Independence (1919–21) and partition of Ireland: most of Ireland became an independent state, while most of Ulster remained within the UK as the self-governing territory of Northern Ireland. During partition, communal violence raged between loyalists and Irish nationalists in Belfast, and loyalists attacked the Catholic minority in retaliation for Irish republican activity.

The governor of Gibraltar is the representative of the British monarch in the British overseas territory of Gibraltar. The governor is appointed by the monarch on the advice of the British government. The role of the governor is to act as the de facto head of state. They are responsible for formally appointing the chief minister of Gibraltar, along with other members of the government of Gibraltar after a general election. The governor serves as commander-in-chief of Gibraltar's military forces and has sole responsibility for defence and security. Although recent appointments have all been former military personnel, most being former Royal Navy or Royal Marines flag officers, Sir James Dutton resigned from the role in 2015, complaining that it was "more representational and ceremonial than I had expected".

The governor has his own flag in Gibraltar, the Union Flag defaced with the territory's coat of arms. However, at the governor's official residence (The Convent), the Union Flag and the flag of Gibraltar are also flown.

The National flag of Canada, popularly referred to as the Maple Leaf, consists of a red field with a white square at its centre in the ratio of 1∶2∶1, in which is featured one stylized, red, 11-pointed maple leaf charged in the centre. It is the first flag to have been adopted by both houses of Parliament and officially proclaimed by the Canadian monarch as the country's official national flag. The flag has become the predominant and most recognizable national symbol of Canada.

In 1964, Prime Minister Lester B. Pearson formed a committee to resolve the ongoing issue of the lack of an official Canadian flag, sparking a debate about a flag change to replace the Union Flag. Out of three choices, the maple leaf design by Mount Allison University historian George Stanley, based on the flag of the Royal Military College of Canada, was selected. The flag officially appeared on February 15, 1965; the date is now celebrated annually as National Flag of Canada Day.

Independence Square (Malay: Dataran Merdeka) is a square located in Kuala Lumpur, Malaysia. It is situated in front of the Sultan Abdul Samad Building. It was formerly known as the Selangor Club Padang, or simply the Padang (meaning "field" in Malay), and was used as the cricket green of the Selangor Club (now the Royal Selangor Club). It was here that the Union Flag was lowered and the Malaysian flag hoisted for the first time at midnight on 31 August 1957. Since then, the Independence Square has been the usual venue for the annual Independence Day Parade.

The funeral of Diana, Princess of Wales, started on Saturday 6 September 1997 at 9:08 am in London, when the tenor bell of Westminster Abbey started tolling to signal the departure of the cortège from Kensington Palace. Diana's coffin was carried from the palace on a gun carriage by riders of the King's Troop and escorted by mounted police along Hyde Park to St James's Palace, where her body had remained for five days before being taken to Kensington Palace. The Union Flag on top of the palace was lowered to half mast. The official ceremony was held at Westminster Abbey in London and finished at the resting place in Diana's family estate of Althorp, Northamptonshire.

Two thousand people attended the ceremony in Westminster Abbey while the British television audience was 32.10 million on average, one of the United Kingdom's highest viewing figures ever. An estimated 2 to 2.5 billion people watched the event worldwide, making it one of the most-watched televised events in history.
