The Chicago Cubs were founded in 1871. They are the oldest MLB team to stay in the same city for their entire history. Their championship drought of over 100 years is the longest in professional sports.
The Cubs were apparently cursed in 1945 by Bill Sianis. Wrigley ejected Sianis and his goat due to complaints about a bad odor. Upon his ejection Sianis muttered, 'The Cubs ain't gonna win no more." The Cubs have not been to a World Series since.
