Mexico gained independence from its colonial rulers in 1821, experiencing periods of stability and tumult in the subsequent decades. But for most of the 20th century, political stasis dominated the country, under the guise of the ruling Institutional Revolutionary Party.
The party also known as PRI began in 1929, 19 years after the launch of the revolution aimed at unseating dictator Porfirio Diaz.
Despite or, perhaps, because of criticisms that it was authoritarian and corrupt, the party won 12 consecutive national elections, which occurred roughly every six years. It wasn't just Mexico City the party controlled: The PRI held most top local and state positions as well, at least until the 1990s.
But its 12-election, 71-year winning streak ended in 2000, when the right-wing National Action Party broke through and Vicente Fox became Mexico's president.
Its ouster from power, however, wasn't permanent. In 2012, PRI unseated its rival party and regained the presidency under Enrique Pena Nieto.
10. Where have you gone, Joe DiMaggio?
In American sports lore, that number speaks for itself. It is forever attached to legendary New York Yankees slugger Joe DiMaggio and his magical run during the 1941 baseball season.
During his career, which was interrupted about halfway by his service in World War II, DiMaggio compiled 361 home runs and a career .325 batting average. That was enough to win him a place in the National Baseball Hall of Fame and, in 1969, the distinction as the sport's greatest living player.
But it's the streak, it seems, that may be his most enduring legacy.
Every season, it seems, a player makes a run at the 56-game hitting streak. And every season, he falls woefully short.
