question:
Passage: Plucknett describes Bracton in this way: "Two generations after Ranulf de Glanvill we come to the flower and crown of English jurisprudence – Bracton." Bracton was born around 1210 in Devon and had a great deal of preferment in the Church. He either derived from Bratton Fleming or Bratton Clovelly. Both villages are in Devon. It was only after his death that the family name appears as Bracton; during his life, he was known as Bratton, or Bretton. This originally may have been Bradton, meaning "Broad Town". Bracton first appeared as a justice in 1245. From 1248 until his death in 1268 he was steadily employed as a justice of the assize in the southwestern counties, especially Somerset, Devon and Cornwall. He was a member of the coram rege, also called the coram ipso rege, later to become the King's Court. He retired from this in 1257, shortly before the meeting of the Mad Parliament in 1258 at Oxford. It is unknown whether his retirement was related to politics. His leaving coincided with the onset of the notorious Second Barons' War in 1264. At that time Bracton was ordered to restore to the Treasury the large store of plea rolls (case records from previous trials) that had been in his possession. He was also forced to surrender the large number of rolls from his predecessors Martin Pateshull and William Raleigh, also known as William de Raley. It cannot be determined whether he disgraced the King or the barons in this affair, but it is speculated that some kind of political intrigue was involved. The practical result was that his major work, De Legibus et Consuetudinibus Angliae ("The Laws and Customs of England"), was left unfinished. Even so, it exists in four large volumes today. He continued to follow the assizes in the southwest until 1267. In the last year of his life he filled another prominent role, as member of a commission of prelates, magnates and justices appointed to hear the complaints of the "disinherited" – those who had sided with Simon de Montfort, 6th Earl of Leicester.

question:
Passage: Dál Riata is said to have been founded by the legendary king Fergus Mór (Fergus the Great) in the 5th century. The kingdom reached its height under Áedán mac Gabráin (). During his reign Dál Riata's power and influence grew; it carried out naval expeditions to Orkney and the Isle of Man, and assaults on the Brittonic kingdom of Strathclyde and Anglian kingdom of Bernicia. However, King Æthelfrith of Bernicia checked its growth at the Battle of Degsastan in 603. Serious defeats in Ireland and Scotland during the reign of Domnall Brecc (died 642) ended Dál Riata's "golden age", and the kingdom became a client of Northumbria for a time. In the 730s the Pictish king Óengus I led campaigns against Dál Riata and brought it under Pictish overlordship by 741. There is disagreement over the fate of the kingdom from the late 8th century onwards. Some scholars have seen no revival of Dál Riatan power after the long period of foreign domination ( to ), while others have seen a revival under Áed Find (736–778). Some even claim that the Dál Riata usurped the kingship of Fortriu. From 795 onward there were sporadic Viking raids in Dál Riata. In the following century, there may have been a merger of the Dál Riatan and Pictish crowns. Some sources say Cináed mac Ailpín (Kenneth MacAlpin) was king of Dál Riata before becoming king of the Picts in 843, following a disastrous defeat of the Picts by Vikings. The kingdom's independence ended sometime after, as it merged with Pictland to form the Kingdom of Alba.
