When was the accordion popular?

The Accordion enjoyed an increase in popularity between the 1930s and 1950s worldwide and this period in history was known as the golden age of the accordion. Piano accordions were invented around 1850 and only became popular around 1910 in America when the Deiro brothers played these instruments on the vaudeville circuit.From the mid 1950s onwards, Rock Music began to take over and new instruments such as the Electric Guitar came into fashion. The accordion was no longer considered important in musical concerts and shows and faded in popularity. It was played only in small gatherings or parties, and acquired an exotic charm. Now, accordions are once again gaining in popularity. Productions of filmmakers like Cirque du Soleil, albums of bands like Those Darn Accordions, and some rock bands have brought the accordion back into the minds of music lovers.
