In addition, in the early 1840s the state legislature and Governor William H. Seward expanded rights for free blacks and fugitive slaves in New York: in 1840 the legislature passed laws protecting the rights of African Americans against Southern slave-catchers. One guaranteed alleged fugitive slaves the right of a jury trial in New York to establish whether they were slaves, and another pledged the aid of the state to recover free blacks kidnapped into slavery, (as happened to Solomon Northup of Saratoga Springs in 1841, who did not regain freedom until 1853.) In 1841 Seward signed legislation to repeal a "nine-month law" that allowed slaveholders to bring their slaves into the state for a period of nine months before they were considered free. After this, slaves brought to the state were immediately considered freed, as was the case in some other free states. Seward also signed legislation to establish public education for all children, leaving it up to local jurisdictions as to how that would be supplied (some had segregated schools).
