In AD 43 the Roman conquest of Britain began; the Romans maintained control of their province of Britannia until the early 5th century. The end of Roman rule in Britain facilitated the Anglo-Saxon settlement of Britain, which historians often regard as the origin of England and of the English people.

Answer:The Burr conspiracy was a plot alleged to have been planned by Aaron Burr in the years during and after his term as Vice President of the United States under US President Thomas Jefferson. According to the accusations against Burr, he attempted to use his international connections and support from a cabal of US planters, politicians, and army officers to establish an independent country in the Southwestern United States and parts of Mexico. Burr's version was that he intended to farm 40,000 acres (160 km2) in the Texas Territory which had been leased to him by the Spanish Crown.
In February 1808, Burr was arrested on Jefferson's orders and indicted for treason, despite a lack of firm evidence. While Burr was ultimately acquitted of treason due to the specificity of the US Constitution, the fiasco further destroyed his already faltering political career. Effigies of his likeness were burned throughout the country and the threat of additional charges from individual states forced him into exile in Europe.[1]
Burr's true intentions remain unclear and, as a result, have led to varying theories from historians: some claim that he intended to take parts of Texas and the newly acquired Louisiana Purchase for himself, while others believe he intended to conquer Mexico or even the entirety of North America. The number of men backing him is also unclear, with accounts ranging from fewer than 40 men to upwards of 7,000
