143 Romans construct the Antonine Wall

The Antonine Wall is a stone and turf fortification built by the Romans across what is now the Central Beltof Scotland. The barrier was the second of two "great walls" created by the Romans in Northern Britain. Its ruins are less evident than the better known Hadrian's Wall to the south. Construction began at the order of Roman Emperor Antoninus Pius, and took about 12 years to complete. In 208 Emperor Septimius Severus re-established legions at the wall and ordered repairs; this has led to the wall being referred to as the Severan Wall. The occupation ended a few years later, and the wall was never fortified again. Most of the wall and its associated fortifications have been destroyed over time, but some remains are still visible. Many of these have come under the care of Historic Scotland and the UNESCO World Heritage Committee.

83 Battle of Mons Graupius

The Battle of Mons Graupius was a Roman military victory in what is now Scotland, taking place in AD 83 or, less probably, 84. The exact location of the battle remains a matter of debate. Even though the Romans were outnumbered in their campaign against the tribes of Britain, they often had difficulties in getting their foes to face them in open battle. The Caledonii were the last unconquered British tribe (and were never fully subdued). After many years of avoiding the fight, the Caledonians were forced to join battle when the Romans marched on the main granaries of the Caledonians, just as they had been filled from the harvest. The Caledonians had no choice but to fight, or starve over the next winter.

2012 Olympic Games

The Olympic Games are considered the world's foremost sports competition with more than 200 nations participating. The Olympic Games are held every four years, with the Summer and Winter Games alternating by occurring every four years but two years apart. Their creation was inspired by the ancient Olympic Games, which were held in Olympia, Greece, from the 8th century BC to the 4th century AD. Baron Pierre de Coubertin founded the International Olympic Committee (IOC) in 1894. The IOC is the governing body of the Olympic Movement, with the Olympic Charter defining its structure and authority. In the 2012 London hosts the Olympic Games for the third time.

2005 London bombings

The 7 July 2005 London bombings (often referred to as 7/7) were a series of coordinated suicide attacks in central London, which targeted civilians using the public transport system during the morning rush hour. The United Kingdom's worst terrorist incident since the 1988 Lockerbie bombing as well as the country's first ever suicide attack. Four Islamist men detonated four bombs - three in quick succession aboard London Underground trains across the city and, later, a fourth on a double-decker bus in Tavistock Square. As well as the four bombers, 52 civilians were killed and over 700 more were injured in the attacks. The 7 July attacks occurred one day after London had won its bid to host the 2012 Olympic Games, which had highlighted the city's multicultural reputation.

1965 Death of Winston Churchill

Sir Winston Leonard Spencer-Churchill (1874 – 1965) was a British politician, the only British Prime Minister to have won the Nobel Prize in Literature, and was the first person to be made an honorary citizen of the United States. He was the Prime Minister of the United Kingdom from 1940 to 1945 and again from 1951 to 1955. Widely regarded as one of the greatest wartime leaders of the 20th century, Churchill was also an officer in the British Army, a historian, a writer, and an artist. Upon his death, Elizabeth II granted him the honour of a state funeral, which saw one of the largest assemblies of world statesmen in history.

1948 National Health Service

The National Health Service (NHS) is the publicly funded healthcare system for England. It is the largest and the oldest single-payer healthcare system in the world. Primarily funded through the general taxation system, the system provides healthcare to every legal resident in the United Kingdom, with most services free at the point of use. In practice, "free at the point of use" normally means that anyone legitimately fully registered with the system can access the full breadth of critical and non-critical medical care without any out-of-pocket payment. Since 1948, patients have been charged for some services such as eye tests, dental care, prescriptions, and aspects of long-term care. However, these charges are often lower than equivalent services provided by a private health care provider.

1939 World War II

The Second World War, was a global war that lasted from 1939 to 1945. The world war is generally said to have begun on 1 September 1939 with the invasion of Poland by Germany and subsequent declarations of war on Germany by France and the United Kingdom. It was the most widespread war in history, and directly involved more than 100 million people, from more than 30 different countries. Marked by mass deaths of civilians, including the Holocaust, the Three Alls Policy, the strategic bombing of enemy industrial and/or population centers, and the first use of nuclear weapons in combat, it resulted in an estimated 50 million to 85 million fatalities. These made World War II the deadliest conflict in human history.
