It's common for a film fan to have heard of the term "Spaghetti Western," but the actual meaning behind it is often misconceived. The Western genre is one of the most common and popular in film history, captivating viewers with stories of cowboys, bounty hunters and outlaws in the American frontier. Widely important in the 20th century, the period between 1940 and 1960 is commonly considered the "Golden Age of the Western." These decades are often remembered for the works of legendary filmmakers such as John Ford. Like any art medium, the Western evolved over time.
