When George I, Elector of Hanover, was crowned King of England in 1714, he established a dynastic union between the two countries that endured until 1837, leaving many cultural and political accomplishments to posterity. The 300th anniversary of this union led the Institute of Landscape Architecture, Technische Universitat Dresden, and the Centre of Garden and Landscape Architecture (CGL), Leibniz Universitat Hannover, to take a critical look at the gardens that resulted. The symposium "Hanover and England: a union of state and garden / German and British garden culture between 1714 and today" was sponsored by the Lower Saxonian Ministry of Science and Culture. The resulting papers dealt with far more than garden history, addressing as well the background and channels by which ideas on art, agriculture, commerce, technology, literature and politics were exchanged. Given the encyclopedic interests of late 18th century thinkers, it was necessary to invite several academic disciplines to participate, in order to describe and discuss the cultural transfer between Great Britain and Hanover. The transfer of horticultural and artistic ideas very often flourished in the 19th century at different places. For this reason, the conference focused on two key aspects: the Hanoverian-British exchange between 1714 and 1837 (the period of the actual royal union) and the Anglo-German relations that endure to the present day.Als Georg I., Kurfurst von Hannover, 1714 zum Konig von England gekront wurde, begrundete dies eine Personalunion zwischen den beiden Landern, die bis 1837 bestand und der Nachwelt eine Vielzahl kultureller und politischer Errungenschaften hinterlie. Das 300-jahrige Jubilaum dieses Zusammenschlusses nahmen das Institut fur Landschaftsarchitektur der Technischen Universitat Dresden und das Zentrum fur Gartenkunst und Landschaftsarchitektur (CGL) der Leibniz Universitat Hannover zum Anlass, sich kritisch mit den in dieser Zeit entstandenen Garten auseinanderzusetzen. Das Symposium "Hanover and England: a union of state and garden / German and British garden culture between 1714 and today" wurde vom Niedersachsischen Ministerium fur Wissenschaft und Kultur gefordert. Die Beitrage beschaftigten sich nicht nur mit Gartengeschichte, sondern widmeten sich auch dem Austausch von Ideen zu Kunst, Landwirtschaft, Handel, Technologie, Literatur und Politik. So schien es sinnvoll, unterschiedliche akademische Disziplinen zur Teilnahme einzuladen, um den kulturellen Transfer zwischen Grobritannien und Hannover zu untersuchen und zu diskutieren. Die Konferenz konzentrierte sich auf zwei Schlusselaspekte: den hannoverisch-britischen Austausch zwischen 1714 und 1837 (die Zeit der Personalunion) und die deutsch-englischen Beziehungen, die bis heute andauern.
