Information:  - Luxembourg, officially the Grand Duchy of Luxembourg, is a landlocked country in western Europe. It is bordered by Belgium to the west and north, Germany to the east, and France to the south. Its capital, Luxembourg City, is, together with Brussels and Strasbourg, one of the three official capitals of the European Union and the seat of the European Court of Justice, the highest juridical authority in the EU. Its culture, people and languages are highly intertwined with its neighbors, making it essentially a mixture of French and Germanic cultures. The repeated invasions by its neighbor countries, especially in World War II, resulted in the country's strong will for mediation between France and Germany and led to the foundation of the European Union.  - The Battle of Worcester took place on 3 September 1651 at Worcester, England, and was the final battle of the English Civil War. Oliver Cromwell's Parliamentarian "New Model Army", 28,000 strong, defeated King Charles II's 16,000 Royalists, of whom the vast majority were Scottish.  - The Irish Sea (, , , Ulster-Scots: "Airish Sea"), separates the islands of Ireland and Great Britain. It is connected to the Celtic Sea in the south by St George's Channel, and to the Inner Seas off the West Coast of Scotland in the north by the North Channel. Anglesey is the largest island within the Irish Sea, followed by the Isle of Man. The sea is occasionally, but rarely, referred to as the Manx Sea.  - Madog ap Llywelyn (died after 1312) was the leader of the Welsh revolt of 129495 against English rule. The revolt was surpassed in longevity only by the revolt of Owain Glyndr in the 15th century. Madog belonged to a junior branch of the House of Aberffraw and was a distant relation of Llywelyn ap Gruffudd, the last recognised native Prince of Wales.  - The Isle of Man, also known simply as Mann, is a self-governing crown dependency in the Irish Sea between England and Northern Ireland. The head of state is Queen Elizabeth II, who holds the title of Lord of Mann. The Lord of Mann is represented by a Lieutenant Governor. Foreign relations and defence are the responsibility of the British Government.  - Gwynedd is an area in north-west Wales, named after the old Kingdom of Gwynedd. As a local government area, it is the second biggest in Wales in terms of geographical area and also one of the most sparsely populated. A majority of the population are Welsh-speaking. The name Gwynedd is also used for a preserved county, covering the two local government areas of Gwynedd and the Isle of Anglesey. Culturally and historically, the name can also be used for most of North Wales (for instance, the area covered by the Gwynedd Constabulary), roughly corresponding to the territory of the Kingdom of Gwynedd at its greatest extent. The current area is 2,548 square km (983.78 sq miles, slightly smaller than Luxembourg) with a population as measured in the 2011 Census of 121,874.  - Cavalier first used by Roundheads as a term of abuse for the wealthier male Royalist supporters of King Charles I and his son Charles II of England during the English Civil War, the Interregnum, and the Restoration (1642  c. 1679). It was later adopted by the Royalists themselves. Although it referred originally to political and social attitudes and behaviour, of which clothing was a very small part, it has subsequently become strongly identified with the fashionable clothing of the court at the time. Prince Rupert, commander of much of Charles I's cavalry, is often considered to be an archetypal Cavalier.  - The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom (UK) or Britain, is a sovereign country in western Europe. Lying off the north-western coast of the European mainland, it includes the island of Great Britain (the name of which is also loosely applied to the whole country), the north-eastern part of the island of Ireland, and many smaller islands. Northern Ireland is the only part of the UK that shares a land border with another sovereign statethe Republic of Ireland. Apart from this land border, the UK is surrounded by the Atlantic Ocean, with the North Sea to its east, the English Channel to its south and the Celtic Sea to its south-south-west, giving it the 12th-longest coastline in the world. The Irish Sea lies between Great Britain and Ireland. With an area of , the UK is the 78th-largest sovereign state in the world and the 11th-largest in Europe. It is also the 21st-most populous country, with an estimated 65.1 million inhabitants. Together, this makes it the fourth most densely populated country in the European Union.  - Tywysog, in modern Welsh, means "Prince", but historically it referred to a broader category of rulers. The feminine form is Tywysoges. The work Brut y Tywysogion is the Annals of the Princes of Wales and is a historical narrative of the deeds of the various rulers of the kingdoms, large and small, which existed in Wales from the end of Roman rule in Britain in c.410AD to the final conquest of Wales and the death of its last consecrated native Tywysog Llywelyn ap Gruffudd of Gwynedd in 1282, who was also the first to bear the title Tywysog Cymru (Prince of Wales). Owain Glyndr, Lord of Glyndyfrdwy, and heir to the Kingdom of Powys, was also proclaimed Tywysog Cymru in 1400 but his rule had come to an end by 1412.  - The Celtic Sea (; ) is the area of the Atlantic Ocean off the south coast of Ireland bounded to the east by Saint George's Channel; other limits include the Bristol Channel, the English Channel, and the Bay of Biscay, as well as adjacent portions of Wales, Cornwall, Devon, and Brittany. The southern and western boundaries are delimited by the continental shelf, which drops away sharply. The Isles of Scilly are an archipelago of small islands in the sea.  - Harlech Castle , located in Harlech , Gwynedd , Wales , is a medieval fortification , constructed atop a spur of rock close to the Irish Sea . It was built by Edward I during his invasion of Wales between 1282 and 1289 at the substantial cost of £ 8,190 . Over the next few centuries , the castle played an important part in several wars , withstanding the siege of Madog ap Llywelyn between 1294 -- 95 , but falling to Owain Glyndr in 1404 . It then became Glyndr 's residence and military headquarters for the remainder of the uprising until being recaptured by English forces in 1409 . During the 15th century Wars of the Roses , Harlech was held by the Lancastrians for seven years , before Yorkist troops forced its surrender in 1468 , a siege memorialised in the song Men of Harlech . Following the outbreak of the English Civil War in 1642 , the castle was held by forces loyal to Charles I , holding out until 1647 when it became the last fortification to surrender to the Parliamentary armies . In the 21st century the ruined castle is managed by Cadw , the Welsh Government 's historic environment service , as a tourist attraction . UNESCO considers Harlech to be one of `` the finest examples of late 13th century and early 14th century military architecture in Europe '' , and it is classed as a World Heritage site . The fortification is built of local stone and concentric in design , featuring a massive gatehouse that probably once provided high - status accommodation for the castle constable and visiting dignitaries . The sea originally came much closer to Harlech than in modern times , and a water-gate and a long flight of steps leads down from the castle to the former shore , which allowed the castle to be resupplied by sea during sieges . In keeping with Edward 's other castles in North Wales , the architecture of Harlech has close to links to that found in the kingdom of Savoy during the same period , an influence probably derived from the Savoy origins of the main architect , James of Saint George .  - Llywelyn ap Gruffudd (c. 1223  11 December 1282), sometimes written as Llywelyn ap Gruffydd, also known as Llywelyn the Last, or, in Welsh, Llywelyn Ein Llyw Olaf, was Prince of Wales (Latin; "Princeps Wallie", Welsh; "Tywysog Cymru") from 1258 until his death at Cilmeri in 1282. The son of Gruffudd ap Llywelyn Fawr and grandson of Llywelyn the Great, he was the last sovereign prince of Wales before its conquest by Edward I of England.  - Owain Glyndr (c. 1359  c. 1415), or Owain Glyn Dr, was a Welsh ruler and the last native Welshman to hold the title Prince of Wales ("Tywysog Cymru"). He instigated a fierce and long-running but ultimately unsuccessful revolt against the English rule of Wales.  - Prince of Wales was a title granted to princes born in Wales from the 12th century onwards; the term replaced the use of the word "king". One of the last Welsh princes, Llywelyn ap Gruffudd, was killed in battle in 1282 by Edward I, King of England, whose son Edward, born in Caernarfon Castle, was invested as Prince of Wales: the first English person to claim the title.   - Cadw (a Welsh verb meaning "to keep/protect") is the historic environment service of the Welsh Government and part of the Tourism and Culture group. Cadw works to protect the historic buildings and structures, the landscapes and heritage sites of Wales, so that the public can visit them, understand their significance and enjoy their experiences. Cadw arranges events at its managed properties, provides lectures and teaching sessions, offers heritage walks and hosts an online shop. Members of the public can become members of Cadw and have such membership privileges as a magazine, reduced prices at the online shop and free entry to properties and most events. It also offers reciprocal arrangements with similar organisations in other parts of the United Kingdom. Cadw offers employment possibilities and work experience placements.  - The Bristol Channel is a major inlet in the island of Great Britain, separating South Wales from Devon and Somerset in South West England. It extends from the lower estuary of the River Severn to the North Atlantic Ocean. It takes its name from the English city of Bristol, and is over 30 miles (50 km) across at its widest point.  - "Men of Harlech" or "The March of the Men of Harlech" (in Welsh: "Rhyfelgyrch Gwr Harlech") is a song and military march which is traditionally said to describe events during the seven-year siege of Harlech Castle between 1461 and 1468. Commanded by Constable Dafydd ap Ieuan, the garrison withstood the longest known siege in the history of the British Isles. "Through Seven Years" is an alternative name for the song. The song has also been associated with the earlier, briefer siege of Harlech Castle about 1408, which pitted the forces of Owain Glyndr against the future Henry V of England.  - The Long Parliament was an English Parliament which lasted from 1640 until 1660. It followed the fiasco of the Short Parliament which had been held for three weeks during the spring of 1640, and which in its turn had followed an 11-years parliamentary absence. In September 1640 writs were issued summoning a parliament to convene on 3 November 1640 by King Charles I. The parliament was summoned to pass financial bills, a step that was necessary as a result of the cost of the Bishops' Wars. It received its name from the fact that through an Act of Parliament, it could be dissolved only with the agreement of the members, and those members did not agree to its dissolution until after the English Civil War and close to the end of Interregnum on 16 March 1660. It sat from 1640 until 1648, when it was purged by the New Model Army. In the chaos following the death of Oliver Cromwell in 1658, General George Monck allowed the members barred in 1648 to retake their seats, so that they could pass the necessary legislation to allow the Restoration and dissolve the Long Parliament. This cleared the way for a new Parliament to be elected, which was known as the Convention Parliament. But many of these original members of Long Parliament, such as were barred from the final acts of the Long Parliament, claimed that the Long Parliament was never legally dissolved.  - The Rump Parliament was the English Parliament after Colonel Thomas Pride purged the Long Parliament, on 6 December 1648, of those members hostile to the Grandees' intention to try King Charles I for high treason.  - Great Britain, also known as Britain , is a large island in the north Atlantic Ocean off the northwest coast of continental Europe. With an area of , Great Britain is the largest European island and the ninth-largest in the world. In 2011 the island had a population of about 61 million people, making it the world's third-most populous island after Java in Indonesia and Honshu in Japan. The island of Ireland is situated to the west of it, and together these islands, along with over 1,000 smaller surrounding islands, comprise the British Isles archipelago.  - England is a country that is part of the United Kingdom. It shares land borders with Scotland to the north and Wales to the west. The Irish Sea lies northwest of England and the Celtic Sea lies to the southwest. England is separated from continental Europe by the North Sea to the east and the English Channel to the south. The country covers five-eighths of the island of Great Britain (which lies in the North Atlantic) in its centre and south; and includes over 100 smaller islands such as the Isles of Scilly, and the Isle of Wight.  - Roundhead was the name given to the supporters of the Parliament of England during the English Civil War. Also known as Parliamentarians, they fought against Charles I of England and his supporters, the Cavaliers or Royalists, who claimed rule by absolute monarchy and the divine right of kings. The goal of the Roundhead party was to give the Parliament supreme control over executive administration.  - Wales is a country that is part of the United Kingdom and the island of Great Britain.

Wales has over of coastline and is largely mountainous, with its higher peaks in the north and central areas, including Snowdon, its highest summit. The country lies within the north temperate zone and has a changeable, maritime climate.  - Henry V (9 August 1386  31 August 1422) was King of England from 1413 until his death at the age of 36 in 1422. He was the second English monarch who came from the House of Lancaster.  - Scotland (Scots: ) is a country that is part of the United Kingdom and covers the northern third of the island of Great Britain. It shares a border with England to the south, and is otherwise surrounded by the Atlantic Ocean, with the North Sea to the east and the North Channel and Irish Sea to the south-west. In addition to the mainland, the country is made up of more than 790 islands, including the Northern Isles and the Hebrides.  - The English Civil War (16421651) was a series of armed conflicts and political machinations between Parliamentarians ("Roundheads") and Royalists ("Cavaliers") over, principally, the manner of England's government. The first (164246) and second (164849) wars pitted the supporters of King Charles I against the supporters of the Long Parliament, while the third (164951) saw fighting between supporters of King Charles II and supporters of the Rump Parliament. The war ended with the Parliamentarian victory at the Battle of Worcester on 3 September 1651.  - Worcester is a city in Worcestershire, England, southwest of Birmingham and north of Gloucester. The population is approximately 100,000. The River Severn flanks the western side of the city centre, which is overlooked by the 12th-century Worcester Cathedral.  - A country is a region that is identified as a distinct national entity in political geography. A country may be an independent sovereign state or one that is occupied by another state, as a non-sovereign or formerly sovereign political division, or a geographic region associated with sets of previously independent or differently associated people with distinct political characteristics. Regardless of the physical geography, in the modern internationally accepted legal definition as defined by the League of Nations in 1937 and reaffirmed by the United Nations in 1945, a resident of a country is subject to the independent exercise of legal jurisdiction.
