Weve come a long way since the first Summer Games in Athens. The year was 1896, and athletes wore a lot more clothes than the athletes wear today.

Women werent even competing then (they started at the 1900 Games in Paris ) and only 14 countries were represented . This years Summer Games has its own set of firsts : Brazil marks the first time a South American country will host the games, its the first time refugees will compete , and the Rio Games will feature the first virtual reality broadcast .

The team at Elle pulled together photos from the Summer Games 120-year history. See the full video above.
