On June 23rd in sports history, one significant event that took place was the famous "Maracanazo" in 1950. This refers to the stunning upset victory of Uruguay over Brazil in the final match of the 1950 FIFA World Cup, held at the Maracana Stadium in Rio de Janeiro, Brazil.

Heading into the match, Brazil was the overwhelming favorite. The host nation only needed a draw to secure the title, while Uruguay had to win outright. An estimated crowd of 200,000 spectators, the largest ever for a football match at the time, packed into the stadium expecting to celebrate Brazil's first World Cup triumph.

However, the match took a surprising turn. Brazil took the lead early in the second half through a goal by Friaça, sending the massive crowd into a frenzy. But Uruguay fought back, equalizing through Juan Alberto Schiaffino in the 66th minute. Then, in the 79th minute, Alcides Ghiggia shocked the world by scoring the winning goal for Uruguay, silencing the Maracana Stadium.

The final whistle confirmed Uruguay's 2-1 victory, securing their second World Cup title. The result left Brazil in a state of national mourning, with the term "Maracanazo" becoming synonymous with the heartbreaking defeat.

The impact of this match went beyond the football field. It is considered one of the biggest upsets in World Cup history and a defining moment in the rivalry between Brazil and Uruguay. The Maracanazo remains a painful memory for Brazilian football fans, and it took the nation 64 years to finally lift the World Cup trophy on home soil in 2014.

In summary, June 23rd, 1950, witnessed one of the most shocking and memorable moments in football history, as Uruguay stunned Brazil in the World Cup final, forever etching the "Maracanazo" into sports folklore.
