The 2000 elections in MEXICO were significant because the Institutional Revolutionary Party (known as PRI) lost the presidency.
The 2000 elections were a turning point in the history of Mexico, because for the first time in the modern era of the nation the Institutional Revolutionary Party was defeated in a presidential election, since since its founding in 1929, all Mexican presidents had been the candidates of this political party, which had governed for more than 70 years.
