The concept that a State's people should vote whether to be a Slave state or Free state

Though slavery is now a widely unaccepted concept, the concept that a State's people should vote whether to be a Slave state or a Free state is still a vivid topic in most history classes.

The concept that a State's people should vote during the time of slavery meant that white men were only allowed to vote. Blacks nor women were allowed to. Along with that, state's believed that by giving men the right to vote whether state should be a Slave or a Free state would fall on the choices of those within the state and what they believed in. It fell under the concept or popular sovereignty, in which people of each state/territory would decided the fate of the State.

this isn't a question and if you're going to list things be kind and use commas.

the fact that could also be added to column b is that during world war ii, specifically between the years 1941 and 1945, japan expanded its territory towards the indonesian territory in what was known later as part of the "pacific war". in that time, japan could conquer the philipines, singapore,   borneo, central java, malang, cebu, sumatra and various other islands of the area, therefore expanding its territory for a brief period of time.
