[4CJ]

What were the abuses the seceding states suffered that caused them to disunite?

Non eneumerated powers exercised by the federal government: protectionist tariffs, subsidization of internal improvements such as canals, roads, railroads, harbours etc., a federal banking system, bounties paid to fishing, shipping and manufacturing interests, the refusal of northern states to abide by their agreement regarding slavery, the attempts to incite insurrections and revolts, the attempts to prevent migration west & northward - which was declared unconstitutional years before - to name a few.

What made the spoiled confederates pick up their ball and go home?

Why couldn't the spoiled yankees abide by the terms of the Constitution and decisions of the US Supreme Court?

[Non-Sequitur]

Don't forget the biggie. What the south viewed as a threat to their institution of domestic slavery.

you- Non eneumerated powers exercised by the federal government: protectionist tariffs, subsidization of internal improvements such as canals, roads, railroads, harbours etc., a federal banking system, bounties paid to fishing, shipping and manufacturing interests, the refusal of northern states to abide by their agreement regarding slavery, the attempts to incite insurrections and revolts, the attempts to prevent migration west & northward - which was declared unconstitutional years before - to name a few.

Is that all of them? I wouldn't want to find out later that I missed an important confederate cause that you forgot to tell me about.

Does failure to support the invasion of Cuba fit in there somewhere?
