Towards the end of the 19th century, a new wave of radicalism came to the East End, arriving both with Jewish émigrés fleeing from Eastern European persecution, and Russian and German radicals avoiding arrest. A German émigré anarchist, Rudolf Rocker, began writing in Yiddish for "Arbayter Fraynd" (Workers' Friend). By 1912, he had organised a mass London garment workers' strike for better conditions and an end to "sweating". Amongst the Russians was fellow anarchist Peter Kropotkin who helped found the Freedom Press in Whitechapel. Afanasy Matushenko, one of the leaders of the Potemkin mutiny, fled the failure of the Russian Revolution of 1905 to seek sanctuary in Stepney Green. Leon Trotsky and Vladimir Lenin attended meetings of the newspaper "Iskra" in 1903, in Whitechapel; and in 1907 Lenin and Joseph Stalin attended the Fifth Congress of the Russian Social Democratic Labour Party held at the Brotherhood Church in De Beauvoir Town. That congress consolidated the leadership of Lenin's Bolshevik faction and debated strategy for the communist revolution in Russia. Trotsky noted, in his memoires, meeting Maxim Gorky and Rosa Luxemburg at the conference.
