Sponsored by Greek businessman Evangelos Zappas, the first modern revival of the Olympic Games took place in Athens.

Evangelos Zappas
Evangelos or Evangelis Zappas was a Greek philanthropist and businessman who is recognized today as one of the founders of the modern Olympic Games, which were held in 1859, 1870, 1875, and 1888 and preceded the Olympic Games that came under the auspices of the International Olympic Committee. These Games, known at the time simply as Olympics, came before the founding of the International Olympic Committee itself. The legacy of Zappas, as well as the legacy of his cousin Konstantinos, was also used to fund the Olympic Games of 1896.
Zappas Olympics
The Zappas Olympics, simply called Olympics at the time, were a series of athletic events held in Athens, Greece, in 1859, 1870 and 1875, sponsored by the Greek businessman Evangelis Zappas. These games were one of the first revivals of the ancient Olympic Games in the modern era. Their success provided further inspiration for William Penny Brookes in England, whose games had been running since 1850, and the International Olympic Committee series from 1896.
Olympic Games
The modern Olympic Games are the world's preeminent international sporting events. They feature summer and winter sports competitions in which thousands of athletes from around the world participate in a variety of competitions. The Olympic Games, open to both amateur and professional athletes, involves more than 200 teams, each team representing a sovereign state or territory. By default, the Games generally substitute for any world championships during the year in which they take place. The Olympics are staged every four years. Since 1994, they have alternated between the Summer and Winter Olympics every two years during the four-year Olympiad.
