GREENVILLE, a city of western Mississippi, U.S.A., on the Mississippi river, 75m. above Vicksburg, at the centre of the Yazoo Delta; the county seat of Washington county. It is served by the Columbus and Greenville and the Yazoo and Mississippi Valley railways, and by river steamers and barges. The population in 192o was 11,56o; 193o was 14,807. It is the trading centre and shipping point for a large part of the Delta, one of the richest agricultural regions of the country, producing about half the cot toil crop of the State. The lumber and dairy industries also are important. Greenville is the only considerable city of the lower Mississippi river which is not built on bluffs, and it suffered gravely in the disastrous floods of 1927. Water reached a height of I 5f t. ; half the population lived for a time in camps on the levees; for weeks the city was accessible only by boat and plane, and no rail road train reached it for two months. Old Greenville, just south of the present site, was the county seat of Jefferson county until 1825, and later of Washington county. Part of it caved into the river, and during the Civil War the town was burned by Federal forces soon after the capture of Memphis. The present site was then adopted for re-building. Greenville was incorporated as a town in 187o, and as a city in 1886.
