Who broke the PRI monopoly in 2000?

The Institutional Revolutionary Party (PRI) monopoly was broken in the 2000 presidential election in Mexico when Vicente Fox, representing the National Action Party (PAN), won the presidency. This marked the first time in 71 years that a candidate from a party other than the PRI took office, signaling a significant shift in Mexican politics. Fox's victory was seen as a culmination of years of electoral reforms and growing public discontent with the PRI's long-standing rule.
