Returning from Istanbul, Herzl traveled to London to report back to the Maccabeans, a proto-Zionist group of established English Jews led by Colonel Albert Goldsmid. In November 1895 they received him with curiosity, indifference and coldness. Israel Zangwill bitterly opposed Herzl, but after Istanbul, Goldsmid agreed to support Herzl. In London's East End, a community of primarily Yiddish speaking recent Eastern European Jewish immigrants, Herzl addressed a mass rally of thousands on 12 July 1896 and was received with acclaim. They granted Herzl the mandate of leadership for Zionism. Within six months this mandate had been expanded throughout Zionist Jewry: the Zionist movement grew rapidly.
