What do the Bill of Rights and the 14th Amendment have in common?

The 14th Amendment was one of three "Reconstruction Amendments." The other two were the 13th and 15th Amendments. The 14th Amendment is currently the longest Amendment to the constitution and was ratified in 1868. One of the major components of the 14th Amendment was that it granted citizenship to all persons born or naturalized in the United States. This was hugely important because it made sure that the recently freed slaves were officially citizens of the United States of America. This guaranteed that they were guaranteed the rights given to United States citizens. The Bill of Rights contains ten of those very important rights. This means that recently freed slaves now have things like the freedom of speech, the right to bear arms, and a host of court protections when accused of a crime.
