Manny Pacquiao vs Marco Antonio Barrera I
On November 15, 2003, Pacquiao faced Marco Antonio Barrera at the Alamodome, San Antonio, Texas, in a fight that many consider to have defined his career. Pacquiao, who was fighting at featherweight for the first time, brought his power with him and defeated Barrera via technical knockout in the eleventh round, the only knockout loss in Barrera's career, and won the Lineal & The Ring Featherweight Championship, making him the first Filipino and Asian to become a three-division world champion, a fighter who won world titles in three different weight divisions. He defended the title twice before relinquishing it in 2005.
On November 24, 2003, the then Philippine President Gloria Macapagal-Arroyo conferred on Pacquiao the Presidential Medal of Merit at the Ceremonial Hall of Malacañan Palace for his knockout victory over the best featherweight boxer of the world. The following day, the members of the House of Representatives of the Philippines presented the House Resolution No. 765, authored by the then House Speaker Jose De Venecia and Bukidnon Representative Juan Miguel Zubiri, which honored Pacquiao the Congressional Medal of Achievement for his exceptional achievements. Pacquiao is the first sportsman to receive such an honor from the House of Representatives."
