Why does the word "prohibition" start with a capital letter? Does it mean something different from its general meaning?

Yes, here, "Prohibition" with a capital letter does mean something slightly different from the usual meaning. It's capitalized because it refers to the nationwide constitutional ban on alcohol in the US from 1920 to 1933. So, "The Prohibition" is a sort of an official title for the ban. Ex: Along with Republican and Democratic parties, Prohibition parties were quite common in the 1920s. Ex: The prohibition of drugs could be quite useful. => general use
