Reconstruction refers to the time immediately following the Civil War, from 1865 to 1877, when many US administrations attempted to rebuild society in the former Confederate states, particularly by establishing and defending the legal rights of the newly liberated black people.

What are Black Codes?

After slavery was abolished during the Civil War, black codes were enacted to limit African Americans' freedom and assure their availability as a cheap workforce.

The Black Codes, sometimes known as Black Rules, were laws that governed the behavior of African Americans (free and freed blacks).

"In most of the United States, there is a division in relation to political advantages, between free white persons and free colored persons of African blood," James Kent wrote in 1832.

Explanation:

The 1876 constitution was in many ways a reaction to the powerful governorship of the 1869 constitution.

What did the Constitution of 1869 provide for the creation of?

The 1869 Constitution included a clause directing the government to establish the Bureau of Immigration, further encouraging economic expansion. The superintendent of the agency was to be chosen by the governor with the Senate's advice and approval. This agency was given the authority to appropriate funding for the establishment of organizations operating in American ports and internationally.

Although clearly excluding the idea of immigration from Africa or Asia, the constitution even advocated the use of state money to pay for immigration from Europe and the transit of newcomers inside the state. Overall, the 1869 Constitution accepted a more patriotic vision of the political system while rejecting the idea of state rights.

Answers

Answer: to limit the power of government and protect property owners

Explanation:

The Bourbons Democrats are Democrats who held political power in Louisiana in the late 1800s, they supported state's right and white supremacy and did not see a need for any change. Bourbons were often seen as being wealthy but uncaring for others especially the poor, so the bourbon Democrats considered themselves southern gentlemen who do not want any change in Louisiana and believe in state's right and being Superior to former slaves.

The Bourbon Democrats pushed for the 1879 constitution to limit the powers of the government so as not to create an enabling equal environment for both citizens of white and black race. Because they oppose equality of political and social structure for non-whites and pinned for a return to the sort of subservient labor force that the agatrian elite white had under slavery. They reduce the term for the governor to one term because they feared for the good intentions of the then Governor Francis Tillou Nicholas, who is a moderate and Confederate war hero that had high ideals, worked to get wealthy citizens to pay their property taxes, and tried to clean up the corrupt Louisiana lottery company

They intend to limit Government power with the 1879 constitution and protect property owners such as the Louisiana company by reducing their tax burdens, and also balanced the budgets by reducing investment in infrastructure such as leeves, Roads, railroads, and social services like education, they feared that education for the masses comprising of non-white who they considered cheap labor supply for agriculture would disrupt steady supply of cheap agricultural labor particularly in rural areas thereby limiting what the government can do
