Ok here’s Sharky’s quick and dirty histography of the invasions of the British Isles. First up is Julius Cesar in 55 BCE. Well his first invasion was in 55, after being initially repulsed by the natives he tried again in 54 BCE with five legions instead of the two he had brought initially. Things seemed to be going well for him but rebellion by some of the gallic tribes he had conquered under Vercingetorix forced him to make a peaceable arrangement with the locals where they would provide Rome tribute in exchange for them forgetting Britain existed.
11 years later the legions of Emperor Claudius conquered the area around what eventually would become London and gradually spread out across the island eventually stopping at a place called the Stanegate. This conquest of the island took till 87 BCE and stopped in the area where Scotland and Britain butt up against one another. I won’t go into Hadrian’s wall here much, but I will say its not accurate to say it was built to keep the Picts out. Historians and Archeologists don’t know the exact reasons why the wall was built, with the keep out the Picts theory being just one of several.
Next up is the Carausian Rebellion in 286 CE, where Romans invaded Roman territory, so I guess it counts? A Roman naval officer named Carausius who had been charged with keeping the English Channel clear of pirates ,decided he liked the sound of Emperor before his name and with the support of the two British legions, the pirates he had been charged to defeat and three gaulic regions rebelled against Rome. This of course sat poorly with the current Emperors of Rome ( don’t ask it’s a long story) so they spent 7 years building up a fleet and steam rolled over Carausius’s allies who had assassinated the man before and were making a general nuisance of themselves to the British populace.
Now we get closer to better documented times, the Saxon Migrations into Britain. By this time, the western roman empire was on the verge of collapse. The outer provinces of the empire were abandoned to their own fates during this time period with the legions guarding them being recalled for Italy’s protection. Into this convenient power vacuum came the Saxons. There were several waves to the migrations of the Saxons over a period of centuries, so it is a bit of an exhaustive topic. The main point ot get is this is what slid Britain from a Romanesque culture into a Germanic one and began the English language’s descent into madness.
im just going to copy a list form Wikipedia now as were getting close to the area of time I don’t know that much about. Hope this has answered some questions, and if not hug it I got to use me degree for the first itme in years.
