Question: When did Christianity become the official religion of the empire that conquered the country in AD 43 where the concept of "chilling out" would develop?

<P0-S0> House and rave clubs such as Lakota and Cream emerged across Britain, hosting house and dance scene events. <P0-S1> In Britain, further experiments in the genre boosted its appeal. <P0-S2> The 'chilling out' concept developed in Britain with ambient house albums such as The KLF's Chill Out and Analogue Bubblebath by Aphex Twin. <P0-S3> The Godskitchen superclub brand also began in the midst of the early 90's rave scene. <P0-S4> After initially hosting small nights in Cambridge and Northampton, the associated events scaled up in Milton Keynes, Birmingham and Leeds. <P0-S5> A new indie dance scene also emerged in the 90's. <P0-S6> In New York, bands such as Deee-Lite furthered house's international influence. <P0-S7> Two distinctive tracks from this era were the Orb's "Little Fluffy Clouds" (with a distinctive vocal sample from Rickie Lee Jones) and the Happy Mondays' "Wrote for Luck" ("WFL") which was transformed into a dance hit by Vince Clarke. <SEP> <P1-S0> Constantine's decision to cease the persecution of Christians in the Roman Empire was a turning point for early Christianity, sometimes referred to as the Triumph of the Church, the Peace of the Church or the Constantinian shift. <P1-S1> The emperor became a great patron of the Church and set a precedent for the position of the Christian emperor within the Church and the notion of orthodoxy, Christendom, ecumenical councils, and the state church of the Roman Empire declared by edict in 380. <P1-S2> In 313, Constantine and Licinius issued the Edict of Milan decriminalizing Christian worship. <P1-S3> He is revered as a saint and isapostolos in the Eastern Orthodox Church, Oriental Orthodox Church, and various Eastern Catholic Churches for his example as a ``Christian monarch. '' <SEP> <P2-S0> conflict between the germanic tribes and the forces of rome under julius caesar forced major germanic tribes to retreat to the east bank of the rhine. <P2-S1> roman emperor augustus in 12 bc ordered the conquest of the germans, but the catastrophic roman defeat at the battle of the teutoburg forest resulted in the roman empire abandoning its plans to completely conquer germany. <P2-S2> germanic peoples in roman territory were culturally romanized, and although much of germany remained free of direct roman rule, rome deeply influenced the development of german society, especially the adoption of christianity by the germans who obtained it from the romans. <P2-S3> in roman-held territories with germanic populations, the germanic and roman peoples intermarried, and roman, germanic, and christian traditions intermingled. <P2-S4> the adoption of christianity would later become a major influence in the development of a common german identity. <SEP> <P3-S0> archaeological finds suggest that the area has been inhabited since the stone age. <P3-S1> following the roman invasion of britain in ad 43 and the conquering of the local britons in 70 ad the fortress settlement of clausentum was established. <P3-S2> it was an important trading port and defensive outpost of winchester, at the site of modern bitterne manor. <P3-S3> clausentum was defended by a wall and two ditches and is thought to have contained a bath house. <P3-S4> clausentum was not abandoned until around 410. <SEP> <P4-S0> Hiberni (Ireland), Pictish (northern Britain) and Britons (southern Britain) tribes, all speaking Insular Celtic, inhabited the islands at the beginning of the 1st millennium AD. <P4-S1> The first Anglo-Saxons arrived as Roman power waned in the 5th century and eventually dominated the bulk of what is now England. <P4-S2> Viking invasions began in the 9th century, followed by more permanent settlements and political change—particularly in England. <P4-S3> The subsequent Norman conquest of England in 1066 and the later Angevin partial conquest of Ireland from 1169 led to the imposition of a new Norman ruling elite across much of Britain and parts of Ireland. <P4-S4> By the Late Middle Ages, Great Britain was separated into the Kingdoms of England and Scotland, while control in Ireland fluxed between Gaelic kingdoms, Hiberno-Norman lords and the English-dominated Lordship of Ireland, soon restricted only to The Pale. <P4-S5> The 1603 Union of the Crowns, Acts of Union 1707 and Acts of Union 1800 attempted to consolidate Britain and Ireland into a single political unit, the United Kingdom of Great Britain and Ireland, with the Isle of Man and the Channel Islands remaining as Crown Dependencies. <P4-S6> The expansion of the British Empire and migrations following the Irish Famine and Highland Clearances resulted in the distribution of the islands' population and culture throughout the world and a rapid de-population of Ireland in the second half of the 19th century. <P4-S7> Much of Brittonic-controlled Britain was conquered by the Roman Empire from AD 43. <P4-S8> Most of Ireland seceded from the United Kingdom after the Irish War of Independence and the subsequent Anglo-Irish Treaty (1919–1922), with six counties remaining in the UK as Northern Ireland.
