The correct answer is A) Abolished slavery in the Confederacy.
The Emancipation Proclamation abolished slavery in the Confederacy. During the tough times of conflict and confrontation during the American Civil War, United States President Abraham Lincoln issued the Emancipation Proclamation on January 1, 1863. This was a very important moment in the history of the United States in that a US President proclaimed that all the slaves in the Confederate states were free.
The proclamation only was valid in the Confederated states that had seceded from the Union, and of course, it was not taken into consideration until many years after the war had ended.
Romanesque architecture is obsessed in semi-circular arches,
massive walls, barrel wall roofs (barrel vault) and decorative arcades
(succession or arches on a walkway). It is markedly different from Gothic
architecture, which is characterized by use of pointed arches. If you are
thinking about fairy-tale castles and stuff, you are probably looking at some
elements of that architecture. Romanesque architecture flourished approximately
6th to 11th centuries, and it is widely adopted by
castles, monasteries, and churches. It got its name probably because of the
arches, which is a feature typical in Ancient Roman architecture. Actually, the
word Romanesque was coined in the 18th century.
