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.
During his youth, Zappas joined the Greek War of Independence, achieving the rank of Major and fighting in several significant battles. Following Greek independence, he moved to Wallachia where he spent most of his life and had a successful career as a businessman, becoming one of the richest men of that time in Eastern Europe.
