The American Civil War (April 12, 1861 – May 9, 1865, also known by other names) was a civil war in the United States fought between northern and Pacific states ("the Union" or "the North") and southern states that voted to secede and form the Confederate States of America ("the Confederacy" or "the South").[e] The central cause of the war was the status of slavery, especially the expansion of slavery into newly acquired land after the Mexican-American War.
The reason behind closing of Ghettos was Typhus and typhoid fever (disease). Ghetto can be defined as a part of a city where minority people or groups used to live due to the result of social and economical pressure. The ghetto is often described as a part or specific society which is more financially weaker than other areas of the city.
Versions of the ghetto appear worldwide, each with its own name, classification, and group of people. The term ghettos was originally used for the Venetian Ghetto in Venice, Italy in 1516, to define the specific part of the city where Jews were not allowed to enter and live, thus they differentiate from other people and created their own place.
