Territorial Governor Samuel W. Black vetoes the Nebraska bill to abolish slavery
Both houses of the Nebraska legislature had voted the week before to abolish slavery in the territory, to become effective in July of that year. There were only around ten slaves held in Nebraska in 1860 but the Buchanan-appointed territorial governor, Samuel W. Black, vetoed the bill on constitutional grounds. A similar bill passed a year later. (By John Osborne)
