There were several different restrictions placed on blacks due to the Jim Crow laws. The following are just a couple examples. 
1) Poll taxes- This was a certain amount of money an individual would have to pay in order to vote. This negatively effected African-Americans, as many of them could not afford this tax. 
2) Literacy tests- These were written tests that individuals had to pass in order to vote. These were extremely difficult to do well on, due to the wording of the question or the time given to complete the test. This targeted African-Americans, as many of them had no formal schooling as of this time period. 
3) Segregated public facilities- Everything from public schools to public pools were segregated in order to keep blacks and whites away from each other. 
        
             
        
        
        
The concept of "total war" refers to a type of armed conflict that is bound by no rules or limitations in terms of who is being attacked, the weapons that are used or the elements of society that will be sacrificed to win it.
Engaging in this type of war can have some benefits, such as:
- There is no need for the government to define its objectives clearly.
 - Because of it, there is no accountability between the government and its citizens, which gives them free reign of action.
 - Countries with a strong military can use their full power.
 
However, the costs far outweigh the benefits:
- Increased cost of human lives, from all parties involved.
 - The destruction of all civil society.
 - Because civil society is so disrupted, government institutions are likely to collapse as well.
 - Extremely difficult recovery process, both politically as economically.
 - Complete depletion of the country's resources.
 - Violation of human rights and the laws of just war.
 - Closes the door to any peaceful solution.
 
There is rarely, if ever, a situation in which a total war provides benefits that would outweigh the costs of it, or that would not be achieved through some other means.
