Legal English the history of the development of English as a legal language. In prehistoric Britain, traditional common law was discussed in the vernacular (see Celtic law). The legal language and legal tradition changed with waves of conquerors over the following centuries. Roman Britain (after the conquest beginning in AD 43) followed Roman legal tradition, and its legal language was Latin. Following the Roman departure from Britain circa 410 and the Anglo-Saxon invasion of Britain, the dominant tradition was instead Anglo-Saxon law, which was discussed in the Germanic vernacular (Anglo-Saxon, Old English), and written in Old English since circa 600, beginning with
Anglo-Saxons and New Zealand – areas which are sometimes referred to as the Anglosphere. The term "Anglo-Saxon" can be used in a variety of contexts, often to identify the English-speaking world's distinctive language, culture, technology, wealth, markets, economy, and legal systems. Variations include the German "Angelsachsen", French "Anglo-Saxon", Spanish "anglosajón", Portuguese "Anglo-saxão", Russian "англосаксы", Polish "anglosaksoński", Italian "anglosassone", Catalan "anglosaxó" and Japanese "Angurosakuson". As with the English-language use of the term, what constitutes the "Anglo-Saxon" varies from speaker to speaker. In modern parlance Anglo-Saxon is increasingly used to define a set of economic belief and systems rooted in anglophone countries. Characteristics
