Impact on the world
Born enslaved on the Davis Bend plantation, where his literate father effectively managed the property's business affairs for its owner (Jefferson Davis's brother), Montgomery inherited both a business education and a post-Reconstruction vision of independent Black land ownership; after the family's own freedman-run plantation collapsed in 1877, he and cousin Benjamin Green purchased 840 acres of Mississippi Delta wilderness in 1887 and built Mound Bayou into a thriving, self-governing community that reached roughly 4,000 residents and 800 landowning families by 1907 — commonly cited as the first and largest all-Black town in the South, with its own bank, newspaper, and, with backing Montgomery personally solicited from Sears, Roebuck chairman Julius Rosenwald through Booker T. Washington, a major cottonseed oil mill. His legacy carries a significant and lasting controversy: as the sole Black delegate to Mississippi's 1890 constitutional convention, he cast the deciding vote in favor of a new constitution that used poll taxes and literacy tests to disenfranchise roughly 123,000 Black voters statewide, a decision Frederick Douglass publicly condemned as “treason” to the cause of Black political rights, even as Douglass acknowledged the anguish behind it and Booker T. Washington later cited Montgomery's accommodationist approach as inspiration for his own 1895 Atlanta Compromise address.
Life & background
Born into slavery on May 21, 1847, at Davis Bend plantation near Vicksburg, Mississippi, to Benjamin Thornton Montgomery and Mary Lewis Montgomery — both literate and given access to their enslaver's extensive library — Isaiah was assigned at age ten as a personal servant to plantation owner Joseph E. Davis, who ran the property according to progressive theories borrowed from industrialist-reformer Robert Owen. During the Civil War he briefly served as a cabin boy for Union Admiral David Dixon Porter before rejoining his family, who purchased Davis Bend outright after the war and built it into Mississippi's third-largest cotton operation before a combination of falling cotton prices, flooding, and his father's 1877 death ended the venture. He served as Mound Bayou's first mayor before resigning in 1902, remained a prominent Mississippi Republican throughout his life — attending the 1904 Republican National Convention and persuading President Theodore Roosevelt to visit Mound Bayou by train in 1905 — and died at his Mound Bayou home on March 5, 1924; his residence, the I.T. Montgomery House, is a National Historic Landmark.
