Kingdom of Gwynedd in the context of "Old Welsh"

The conquest of Wales by Edward I took place between 1277 and 1283. It is sometimes referred to as the Edwardian conquest of Wales, to distinguish it from the earlier (but partial) Norman conquest of Wales. In two campaigns, in 1277 and 1282–83, respectively, Edward I of England first greatly reduced the territory of Llywelyn ap Gruffudd ("Llywelyn the Last"), and then completely overran it, as well as the other remaining Welsh principalities.

By the 13th century, Wales was divided between native Welsh principalities and the territories of the Anglo-Norman Marcher lords. The leading principality was Gwynedd, whose princes had gained control of the greater part of the country, making the other remaining Welsh princes their vassals, and had taken the title Prince of Wales. Although English monarchs had made several attempts to seize control of the native Welsh territories, it was not until Edward's war of conquest against Llywelyn, the last native prince of Wales, that this was achieved on a lasting basis.

Prince of Wales is a title traditionally given to the male heir apparent to the English, and later, the British throne. The title originated with the Welsh rulers of Gwynedd who, from the late 12th century, used it (albeit inconsistently) to assert their supremacy over the other Welsh rulers. However, to mark the finalisation of his conquest of Wales, in 1301, Edward I of England invested his son Edward of Caernarfon with the title, thereby beginning the tradition of giving the title to the heir apparent when he was the monarch's son or grandson. The title was later claimed by the leader of a Welsh rebellion, Owain Glyndŵr, from 1400 until 1415.

Lleu Llaw Gyffes (Welsh pronunciation: [ˈɬɛɨ ˈɬau ˈɡəfɛs]), sometimes incorrectly spelled as Llew Llaw Gyffes, is a hero of Welsh mythology. He appears most prominently in the Fourth Branch of the Mabinogi, the tale of Math fab Mathonwy, which tells the tale of his birth, his marriage, his death, his resurrection and his accession to the throne of Gwynedd. He is a warrior and magician, invariably associated with his uncle Gwydion.

His name appears to be the Welsh equivalent of the Irish Lugh and the Gaulish Lugus. It has been suggested that Lleu, like Pryderi, is related to the divine son figure of Mabon ap Modron.

Magnus III Olafsson (Old Norse: Magnús Óláfsson, Norwegian: Magnus Olavsson; 1073 – 24 August 1103), better known as Magnus Barefoot (Old Norse: Magnús berfœttr, Norwegian: Magnus Berrføtt), was the King of Norway from 1093 until his death in 1103. His reign was marked by aggressive military campaigns and conquest, particularly in the Norse-dominated parts of Ireland and Britain, where he extended his rule to the Kingdom of the Isles and Dublin.

As the only son of King Olaf Kyrre, Magnus was proclaimed king in southeastern Norway shortly after his father's death in 1093. In the north his claim was contested by his cousin, Haakon Magnusson (son of King Magnus Haraldsson), and the two co-ruled uneasily until Haakon's death in 1095. Disgruntled members of the nobility refused to recognise Magnus after his cousin's death, but the insurrection was short-lived. After securing his position domestically, Magnus campaigned around the Irish Sea from 1098 to 1099. He raided through Orkney, the Hebrides and Mann (the Northern and Southern Isles), and ensured Norwegian control by a treaty with the Scottish king. Based on Mann during his time in the west, Magnus had a number of forts and houses built on the island and probably also obtained suzerainty of Galloway. He sailed to Wales later in his expedition, gaining the support of Anglesey (and the Gwynedd) after aiding against the invading Norman forces from the island.

The Battle of Catraeth was a legendary battle fought around AD 600 between a force raised by the Gododdin, a Brythonic people of the Hen Ogledd or "Old North" of Britain, and the Angles of Bernicia and Deira. It was evidently an assault by the Gododdin party on the Angle stronghold of Catraeth, perhaps Catterick, North Yorkshire. The Gododdin force was said to have consisted of warriors from all over the Hen Ogledd, and even some from as far afield as Gwynedd in North Wales and Pictland. The battle was disastrous for the Britons, who were nearly all killed. The slain warriors were commemorated in the important early poem Y Gododdin, attributed to Aneirin.

The history of what is now Wales (Welsh: Cymru) begins with evidence of a Neanderthal presence from at least 230,000 years ago, while Homo sapiens arrived by about 31,000 BC. However, continuous habitation by modern humans dates from the period after the end of the last ice age around 9000 BC, and Wales has many remains from the Mesolithic, Neolithic, and Bronze Age. During the Iron Age, as in all of Britain south of the Firth of Forth, the culture had become Celtic, with a common Brittonic language. The Romans, who began their conquest of Britain in AD 43, first campaigned in what is now northeast Wales in 48 against the Deceangli, and gained total control of the region with their defeat of the Ordovices in 79. The Romans departed from Britain in the 5th century, opening the door for the Anglo-Saxon settlement. Thereafter, the culture began to splinter into a number of kingdoms. The Welsh people formed with English encroachment that effectively separated them from the other surviving Brittonic-speaking peoples in the early middle ages.

In the post-Roman period, a number of Welsh kingdoms formed in present-day Wales, including Gwynedd, Powys, Ceredigion, Dyfed, Brycheiniog, Ergyng, Morgannwg, and Gwent. While some rulers extended their control over other Welsh territories and into western England, none were able to unite Wales for long. Internecine struggles and external pressure from the English, and later the Norman conquerors of England, led to the Welsh kingdoms coming gradually under the sway of the English crown. In 1282, the death of Llywelyn ap Gruffudd led to the conquest of the Principality of Wales by King Edward I of England; since then, the heir apparent to the English monarch has borne the title "Prince of Wales". The Welsh launched several revolts against English rule, the last significant one being that led by Owain Glyndŵr in the early 15th century. In the 16th century Henry VIII, himself of Welsh extraction as a great-grandson of Owen Tudor, passed the Laws in Wales Acts aiming to fully incorporate Wales into the Kingdom of England.

This is a list of the rulers of the Kingdom of Gwynedd. Many of them were also acclaimed "King of the Britons" or "Prince of Wales".

Llywelyn ap Seisyll (died 1023) was a king of Gwynedd in the 11th century who ruled over the Welsh kingdoms of Gwynedd, Powys and Deheubarth.

Maredudd ab Owain (died c. 999) was a Welsh monarch, ruling in Gwynedd, Deheubarth and Powys. A member of the House of Dinefwr, his patrimony was the kingdom of Deheubarth comprising the southern realms of Dyfed and Seisyllwg. Upon the death of his father King Owain ap Hywel Dda around 988, he also inherited the kingdoms of Gwynedd and Powys, which he had conquered for his father. He was counted among the Kings of the Britons by the Chronicle of the Princes.

Maredudd was the younger son of King Owain ap Hywel Dda of Deheubarth and the grandson of King Hywel Dda. Owain had inherited the kingdom through the early death of his brothers and Maredudd, too, came to the throne through the death of his elder brother Einion around 984. Around 986, Maredudd captured Gwynedd from its king Cadwallon ab Ieuaf. He may have controlled all Wales apart from Gwent and Morgannwg.
