The area now called England was first inhabited by modern humans during the Upper Palaeolithic period, but takes its name from the Angles, one of the Germanic tribes who settled during the 5th and 6th centuries. England became a unified state in the 10th century, and since the Age of Discovery, which began during the 15th century, has had a significant cultural and legal impact on the wider world.[6] The English language, the Anglican Church, and English law – the basis for the common law legal systems of many other countries around the world – developed in England, and the country's parliamentary system of government has been widely adopted by other nations.[7] The Industrial Revolution began in 18th-century England, transforming its society into the world's first industrialised nation.[8]
