The southern(who were previously Confederate) states all wrote new Constitutions and swore loyalty to the Union by 1877. Also, the 13th amendment(which states no slavery n<span>or involuntary servitude</span> is allowed unless punishment... in u.s.), 14th amendment(forbids states to restrict simple rights of citizens etc,), and 15th amendment(citizens in U.S. cannot be denied due to race, color, etc. to vote) were acknowledged and remained after the reconstruction. Former slaves also had a new life ahead of them: they could now be educated, choose who they wanted to marry, and choose jobs. Unfortunately, the reconstruction didn't heal African American/ white man wounds; and even though there were laws for equality, for many upcoming years, many black people still had many problems with white people who still believed they were somehow superior.
A country needs rules about citizens cause in reality you cant have random people, bad record or not, coming in your country and just being a citizen instantly without any proof of trust, little do they know they could be a terrorist with the rights of a citizen just cause theirs no way to justify who's one or not.
