Lands of the Crown of Saint Stephen

The Lands of the Crown of Saint Stephen (Hungarian: a Szent Korona Országai, lit. 'Countries of the Holy Crown'), informally Transleithania (meaning the lands or region "beyond" the Leitha River), were the Hungarian territories of Austria-Hungary, throughout the latter's entire existence (30 March 1867 – 16 November 1918), and which disintegrated following its dissolution. The name referenced the historic coronation crown of Hungary, known as the Crown of Saint Stephen of Hungary, which had a symbolic importance to the Kingdom of Hungary.
