The University of Wales was founded in Wales in 1893 as a federal university with three foundation colleges: University College Wales which had been founded in 1872 and University College North Wales Now Bangor University and University College South Wales and Monmouthshire which were founded following the Aberdare Report in 1881. Prior to the foundation of the federal University, these three colleges had prepared students for the examinations of the University of London. A fourth college, Swansea Now Swansea University, was added in 1920 and in 1931 the Welsh School of Medicine was established in Cardiff.
