Why was thomas Jefferson attack on slavery removed from the declaration of independence?

Thomas Jefferson's attack on slavery was removed from the Declaration of Independence primarily due to pressure from Southern delegates who depended on slave labor for their economy. They opposed any language that would criticize or abolish slavery, fearing it would threaten their interests. Additionally, the Continental Congress aimed for unity among the colonies, and including such a contentious issue could jeopardize the collective effort against British rule. Ultimately, to secure broader support for independence, compromises were made that excluded Jefferson's condemnation of slavery.
