Works were written primarily for mass-appeal, focusing on more commonly known subjects such as history and theology. The literary scene became more diverse when African-American writers were accepted into the mix. (Benjamin Franklin)
New social and political thought was introduced during this era. Ideas were only just beginning to solidify and propositions were being bandied around in the written word. I am familiar with all of these writers (Thomas Jefferson, James Madison) and some of their works, excluding the poets.

An American style of literary expression began to solidify as genres were established. Uniquely American works were created during this shift away from British . The stories of slaves were written by freed and escaped slaves. (Edgar Allan Poe, Frederick Douglas)
