In 43 AD, the Roman Empire, under Emperor Claudius, launched a significant military campaign to conquer Britain. This marked the beginning of Roman rule in the region, which would last for nearly four centuries. The invasion was led by General Aulus Plautius, who successfully captured key territories and established Roman control. The conquest of Britain in 43 AD led to the establishment of several Roman settlements and the introduction of Roman culture, law, and infrastructure. This period saw the construction of roads, forts, and towns, which facilitated trade and communication across the newly acquired territory.
