Grant was considered an effective civil rights president, concerned about the plight of African Americans. On March 18, 1869, Grant signed into law equal rights for blacks, to serve on juries and hold office, in Washington D.C., and in 1870 he signed into law the Naturalization Act that gave foreign blacks citizenship. During his first term, Reconstruction took precedence. Republicans controlled most Southern states, propped up by Republican controlled Congress, northern money, and southern military occupation. Grant advocated the ratification of the Fifteenth Amendment that said states could not disenfranchise African Americans. Within a year, the three remaining states—Mississippi, Virginia, and Texas—adopted the new amendment—and were admitted to Congress. Grant put military pressure on Georgia to reinstate its black legislators and adopt the new amendment. Georgia complied, and on February 24, 1871 its Senators were seated in Congress, with all the former Confederate states represented.
