thumb|right|Cosima and Richard Wagner at their home Wahnfried, with Liszt and Hans von Wolzogen (1880) By 1864 Wagner had begun an affair with Liszt's daughter Cosima, who was married to Liszt's erstwhile pupil Hans von Bülow. Liszt disapproved of the relationship and broke off contact with the couple for a number of years, only learning of their 1870 marriage from the newspapers. Nevertheless the relationship recovered: Liszt contributed financially to the building of the Bayreuth Festspielhaus in 1871, and he began to correspond with Wagner and Cosima again, frequently visiting their home Wahnfried. Liszt died in 1886 while at the latest incarnation of the Bayreuth Festival, dedicated to Wagner's work, Wagner having died three years previously.
