Why did Jefferson's references to slavery not appear in the final version declaration?

Jefferson's references to slavery were omitted from the final version of the Declaration of Independence primarily due to political compromise. Southern delegates, concerned about the potential backlash from slaveholding states, strongly opposed any condemnation of slavery. Additionally, the need for unity among the colonies to fight against British rule took precedence, leading to the removal of contentious language that might alienate crucial support. This decision reflected the complex social and political realities of the time, prioritizing immediate goals over moral considerations.
