Answer:
Signs were used to indicate where non-whites could legally walk, talk, drink, rest, or eat. The U.S. Supreme Court upheld the constitutionality of segregation in Plessy v. Ferguson (1897), so long as "separate but equal" facilities were provided, a requirement that was rarely met in practice.
Explanation:
The doctrine was overturned in Brown v. Board of Education (1954) unanimously by the Supreme Court under Chief Justice Earl Warren, and in the following years the Warren Court further ruled against racial segregation in several landmark cases including Heart of Atlanta Motel, Inc. v.

King Geroge the Third's Intolerable Acts Laws were unfair because it was a way to punish the colonists by enlisting taxes on imports and exports. Other unfair laws include the Boston Port Act and the Quartering Act which required citizens to house British soldiers and provide them food and water without any say in the matter.
The number of African-American slaves was rapidly increasing and combined with the poor white people they started to outnumber the white rich majority. If they ever decided to unite and to overthrow the institutions of power, they could make their own government where there would be no place for those who were white and rich plantation owners.
They countered this through various laws. For example, they forbid African-Americans from arming themselves even if they were free, or they forbid them from mixing up with local native population. If there would be miscegenation, the child would be a slave and live with African-Americans even though their fathers would be those same white rich people. They got the support of the poor white people because they would amnesty those who would rebel against them.
