No, While a Few states Did secede over Slavery, Most Seceded over (At-the-time)unlawful Federal Taxes(such because the Cotton Tax), as a result Violating the tenth Amendment Slavery was once an Issue for the period of the War, however it was once a Small one, Most humans within the South did not even possess Slaves, so much humans who did have been the Wealthy, and as Such so much humans had no Reason to visit conflict over Slavery, on the grounds that they did not even possess any. the South went to conflict over a Northern Union that had Violated the Constitution, Such because the tenth Amendment ---------------------------------- Edit:The Following is simply to Further Explain the Point I was once Trying to make! Do you suppose President Abraham Lincoln Was A Tyrant/Northern Extremist? Personally I suppose he was once a Northern Extremist on the grounds that he Forced the Southern States to Pay(on the time) unlawful Federal Taxes. Specifically The worst of those Taxes was once the Cotton Tax, The Cotton Industry(on the time) was once the South's handiest Major Industry that the Northern States did not have, And I order to aid their Industry powerful and rapid developing the Southern States had positioned little or no Taxes at the Trade, The North However Violated the Constitution by way of Initiating a Federal Cotton Tax at the Cotton Industry with none of the State's Permission, This Normally shouldn't have been a huge deal, besides for the truth that this Tax was once three instances bigger then the Income Tax(of the time), It Nearly Crippled the Cotton Industry as a Result, What made it worse was once all the Farmers within the South who many have been already slightly making it by way of as is, have been out of the blue confronted with huge Losses and an Inability to Maintain their Livelihoods. He even Temporarily Suspended Rights to Habeas Corpus. He had humans who adversarial him Arrested, and Thrown in Jail, with out Trial and even telling them what they'd been charged with! And I recognise People will convey up matters like Fort Sumpter to check out and make it sound just like the Confederates have been the Aggressors, whilst In Reality at that Time the southern states had already Seceded from the Union, which supposed that the Fort was once then in Confederate Territory, Which from the Confederate Perspective the Fort was once being occupied by way of Foreign Troops in Confederate Territory. This could be like if the United States had a Base in Canada with out the Canadians Permission, If we did that the Canadians could have the Authority to drive us to depart, and the equal is going for Fort Sumpter!
