Final answer:
The first round of reconstruction cannot be described by restoring the 11 ex-Confederate states and the establishment of Black Codes.
Step-by-step explanation:
The statement that the first round of reconstruction can be best described by restoring the 11 ex-Confederate states and the establishment of Black Codes is False.
The Black Codes were a series of discriminatory state laws passed by southern states in 1865-1866. They were designed to maintain the social and economic structure of racial slavery in the absence of slavery itself by restricting the rights of freed enslaved people.
The first Reconstruction Act passed in 1867 divided the South into military districts, not the first round of reconstruction.
