What three long term causes of the civil war do historians most often point to?

Slavery is often cited as the main cause for the civil war but other problems related to political and cultural differences between the North and the South were also responsible.

Few other causes were-

Bleeding Kansas- In 1854, the government passed the Kansas-Nebraska act and asked its people to vote for their state if they wanted a slave state or free state. After many years of fighting Kansas was a free state.

Industry v/s farming- In 1800's the Northern state needed no slaves as they moved to major cities like New York and Boston and moved away from farming to industrialization. But the Southern states relied heavily on forced slave labor as they had vast farming economy.

Abraham Lincoln- He was a member of the new anti-slavery Republican Party. So the Southern states felt he was against slavery and also against the South.

tenochtitlan (also spelled tenochtitlán), located on an island near the western shore of lake texcoco in central mexico, was the capital city and religious centre of the aztec civilization. the traditional founding date of the city was 1345 ce and it remained the most important aztec centre until its destruction at the hands of the conquering spanish led by hernán cortés in 1521 ce, which led to the final collapse of the aztec empire.

when a country suffers, for example, a drought period, the market product is affected for a low offer, in this case, potatoes; the government has to tax to the households, which have to give more money for the potatoes which they consume, that situation make them consume substitute goods even through loans, it could increase the financial market movement and the inflationary phenomena, the business has to increase salaries in order to the employees could buy a more expensive food (potatoes) and in order to inflation tha business had to buy expensive supplies in the factor market, while the rest of the world have to gain more money to consume the same amount of potatoes.
