the Sun" with another leader "Europe's Poweder Keg", predicating that the continuance of the Treaty of Trianon would cause another world war. Rothermere explained his support for Hungary in racial terms, arguing that it was only "natural" for "superior" peoples to dominate "inferior" peoples, and liked the situation with Magyars under Czechoslovak, Yugoslav and Romanian rule as being alike to the situation that would occur if people from Britain's colonies were ruling over the British people. Many in England were caught off-guard by Rothermere's impassioned endorsement of the Hungarian cause, and it was rumoured that the press baron had been convinced to support it by the charms of a Hungarian seductress, who was later identified as the Austrian Stephanie von Hohenlohe, a princess by marriage. Rothermere's leader caused immense concern in Yugoslavia, Czechoslovakia and Romania, where it was believed that his leader reflected British government policy. The Czechoslovak Foreign Minister Edvard Beneš was so concerned that he visited London to meet King George V, a man who detested Rothermere and used language that was so crude, vulgar and "unkingy" that Beneš had to report to Prague that he could not possibly repeat the king's remarks in print. In fact, Rothermere's "Justice for Hungary" campaign, which he continued until February 1939, was a source of disquiet for the Foreign Office, which complained that British relations with Czechoslovakia, Yugoslavia and Romania were constantly stained as the leaders of those nations continued to harbor the belief that Rothermere was in some way speaking for the British government. One man who was better informed was one of Rothermere's principle opponents, the Czechoslovak minister-plenipotentiary in London, Jan Masaryk. Masaryk reported to Prague that Rothermere was not acting on behalf of Whitehall, but rather on behalf of Princess von Hohenlohe. Masaryk described Rothermere as dominated both emotionally and sexually by Hohenlohe, writing that he would do anything to please her. Masaryk cynically predicated that Rothermere would lose interest in Hungarian revanchism the moment he found himself a new mistress. In a letter dated 30 April 1928, Rothermere admitted to the Princess von Hohenohe: "As I have already told you on several occasions, my interest in Hungary was aroused principally by you. I had no idea that the enumeration of Hungary's woes and her unfair treatment would trigger off such worldwide sympathy". Sir Austen Chamberlain, the Foreign Secretary told Count István Bethlen, the Hungarian Prime Minister, during
