Celtic Studies (or Celtology) is the study of the cultures of Celtic-speaking societies in all their manifestations, whether linguistic, historical or material, as well as the cultures of formerly Celtic-speaking communities that have preserved "Celtic" cultural traditions.
The Celtic cultures have had a major influence on Europe for over two millennia. The regions where Celtic languages are still spoken today and where Celtic traditions are maintained or revived, all belonged to the European Union until 31.1.2020 with the exception of the Isle of Man, which is an autonomous possession of the British Crown. Irish has been one of the official languages of the EU since 2007.
Britain's withdrawal from the EU, the so-called "Brexit", means a split in the Celtic regions. Scotland, Northern Ireland and parts of Wales (Gwynedd, Ceredigion, Cardiff, Vale of Glamorgan) have voted by majority against leaving in 2016.
Despite the great importance of Celtic cultures for the history, identity and integration of Europe, Celtic Studies, with the exception of archaeology, is hardly represented at educational and research institutions in the EU outside the Celtic regions themselves.
Since the closure of Celtic Studies at the Humboldt University Berlin in 1997, there is currently only one chair in Germany dedicated to this subject in Marburg, where courses of study up to doctoral level are offered (see below).
