who lost a lot of their power after the battle of culloden in 1746
Battle of Culloden Queen Anne, the last monarch of the House of Stuart, died in 1714, with no living children. Under the terms of the Act of Settlement 1701, she was succeeded by her second cousin George I of the House of Hanover, who was a descendant of the Stuarts through his maternal grandmother, Elizabeth, a daughter of James VI and I. The Hanoverian victory at Culloden halted the Jacobite intent to overthrow the House of Hanover and restore the House of Stuart to the British throne; Charles Stuart never again tried to challenge Hanoverian power in Great Britain. The conflict was the last pitched battle fought on British soil.[5]
End of Roman rule in Britain In 383, the usurper Magnus Maximus withdrew troops from northern and western Britain, probably leaving local warlords in charge. Around 410, the Romano-British expelled the magistrates of the usurper Constantine III, ostensibly in response to his failures to use the Roman garrison he had stripped from Britain to protect the island. Roman Emperor Honorius replied to a request for assistance with the Rescript of Honorius, telling the Roman cities to see to their own defence, a tacit acceptance of temporary British self-government. Honorius was fighting a large-scale war in Italy against the Visigoths under their leader Alaric, with Rome itself under siege. No forces could be spared to protect distant Britain. Though it is likely that Honorius expected to regain control over the provinces soon, by the mid-6th century Procopius recognised that Britannia was entirely lost to the Romans.
