The first large wave of emigration from Hungary to the United States occurred in 1849-1850, when the so-called "Forty-Eighters" fled from retribution by Austrian authorities after the defeat of the Hungarian Revolution of 1848. Lajos Kossuth gave a seven-month speaking tour of the US in 1851 and 1852 to great acclaim as a champion of liberty, thereby unleashing a brief outburst of pro-Hungarian emotions. He left embittered because his refusal to oppose slavery alienated his natural constituency, and his long-term impact was minimal. By 1860, 2,710 Hungarians lived in the US, and at least 99 of them fought in the Civil War. Their motivations were not so much antislavery as a belief in democracy, a taste for adventure, validation of their military credentials, and solidarity with their American neighbors.
