Get ready to watch the Opening Ceremony: Parade of nations
A parade of delegates made up of athletes and coaches from each participating nation made its debut at the 1908 Olympic Games in London.
For the 1928 Amsterdam Olympic Games a new tradition was started which remains to this day: Greece's Olympians are honored by entering the Olympic stadium first and the delegation from the host nation enters last. The parade order for the rest of the delegations follows the alphabetical order of the native language of the host nation.
The Portuguese alphabet will be used for the Parade of Nations during the Rio Opening Ceremony. English-speaking audiences will be able to easily follow the alphabetic sequence as it is identical to the alphabet they learned in school. It should be noted, K, W and Y are only used in Brazilian Portuguese in words which are borrowed from other languages.
Commonly selected by their national team peers, every delegation marches into the Opening Ceremony behind an athlete given the honor of carrying their country's flag. At the most recent Olympic Games in London, the task of leading Team USA into the Opening Ceremony was handed to fencer Mariel Zagunis.
