The NCAA Men’s College Basketball Tournament, otherwise known as March Madness, leads Americans to create brackets every year and often bet money on their picks. This year, a series of upsets – none other as notorious as the University of Virginia’s (UVA)  loss to the University of Maryland, Baltimore County (UMBC) – have caused brackets nationwide to perish.

In a round one game on March 16, the 16-seed UMBC Retrievers beat the 1-seed UVA Cavaliers in a 74-54 upset that made history. This game was the first time that a 16-seed beat a 1-seed in the history of the NCAA Men’s College Basketball Tournament since its origin in 1939. The game wasn’t even close—the Retrievers won by 20 points.

“We believe in each other, coaching staff did a good job on the scout, and we did it. We did it. It’s a dream come true,” junior point-guard K.J. Maura told For The Win.

UMBC then went on to face 9-seed Kansas State University Wildcats March 18. They lost 50-43 in regulation. Although receiving elimination from the tournament, the Retrievers were honored at Maryland Governor Larry Hogan’s mansion and received senate recognition, The Washington Post reported. UMBC renewed head coach Ryan Odom’s contract as well.

“UMBC has been so good to my family, and we’re so excited about the opportunity to continue to lead these guys,” Odom told the Post. “It’s a special community, and we’re excited to be a part of it.”

Loyola University Chicago (11-seed) also proved to be a force to be reckoned with, after defeating 6-seed Miami University, 3-seed University of Tennessee, and 9-seed Kansas State University, putting them in the final four in San Antonio.

The Loyola Chicago Ramblers became “just the fourth No. 11 seed to reach the Final Four in the history of the NCAA Division I men’s basketball tournament,” CNN reported.

The team’s chaplain, 98 year-old nun Sister Jean Dolores-Schmidt, has become a symbol of their hard work and victory, BBC reported.

“Congrats to @LoyolaChicago and Sister Jean for a last-second upset – I had faith in my pick!” former U.S. president Barack Obama posted.

The State University of New York at Buffalo (13-seed) pulled off an upset vs. the University of Arizona (4-seed) 89-68. They were then defeated in the second round by University of Kansas (5-seed).

Each year of March Madness results in upsets, but this year’s tournament made history with the UMBC vs. Virginia game.
