(n.) The currency of the United States
and its' dependancies. Has been steadily increasing in power since first inception. In the mid 20th century it was approx £1= $4 as the united states became the superpower of the post-war era. The dollar peaked at £1= $.65, and is slowly dropping in value as the US begins its' economic descent, paving the way for another superpower; without a steadfast empire, no country or region can remain the superpower(s) of the world for long. Within a century of losing the empire, country will slide down the power league. This has been seen in Britain and France, and before that, the spark-empire of Spain, which was later sold cheaply to the US. This empire lasted only a short amount of time, and caused some degree of embarrassment when lost.
