Nearly all political terms were political neologisms at some point. Left and right gained their political meaning after the seating arrangement of the French revolutionary assembly, in 1789. Bolshevik started in 1903, when the Russian revolutionary party, the Social Democrats split into the Mensheviks and Bolsheviks ("men'she" in Russian means "minority" and "bol'she" in Russian means "majority"). The term entered popular parlance after the 1917 Russian Revolution.

This category is for terms that have entered political jargon since approximately 2001; their first use may be earlier, but their widespread use should not be. Terms of such relative novelty may be forgotten in 100 years, or they may seem like the only sensible and neutral way to express the concepts they cover—if a term is listed here, it is too early to tell its eventual linguistic fate.
