On 10 March 1896, Herzl was visited by Reverend William Hechler, the Anglican minister to the British Embassy in Vienna. Hechler had read Herzl's "Der Judenstaat", and the meeting became central to the eventual legitimization of Herzl and Zionism. Herzl later wrote in his diary, "Next we came to the heart of the business. I said to him: (Theodor Herzl to Rev. William Hechler) I must put myself into direct and publicly known relations with a responsible or non responsible ruler – that is, with a minister of state or a prince. Then the Jews will believe in me and follow me. The most suitable personage would be the German Kaiser." Hechler arranged an extended audience with Frederick I, Grand Duke of Baden, in April 1896. The Grand Duke was the uncle of the German Emperor Wilhelm II. Through the efforts of Hechler and the Grand Duke, Herzl publicly met Wilhelm II in 1898. The meeting significantly advanced Herzl's and Zionism's legitimacy in Jewish and world opinion.
