Some 80,000 people gathered in this capital's Zocalo plaza early Monday to celebrate the historic victory of left-wing President-elect Andres Manuel Lopez Obrador, a win that ended the virtual two-party system in place since the implementation of Mexico's democratic system.

The sound of horns filled the air along Reforma Avenue, which runs across the city from north to south, while thousands congregated outside the downtown hotel where Lopez Obrador gave his first address as president-elect.

The landslide victory became evident shortly after the polls closed, prompting the losing presidential candidates to concede defeat and hastening celebrations all over the country.

With three giant television screens and the emblematic Latinoamericana tower engulfed in the colors of the Mexican flag as a backdrop, thousands of excited and hopeful citizens applauded the president-elect's speech while chanting "It is an honor to be with Obrador!" and "Yes we could!"

In his address, the 64-year-old former Mexico City mayor urged "national reconciliation" before making his way to the Zocalo, the largest plaza in the capital, where he led mass protests in the past blaming losses in the 2006 and 2012 elections to National Action Party (PAN) and Institutional Revolutionary Party (PRI) candidates, respectively, on fraud.

Among his most acclaimed proposals were the defense of indigenous peoples, the fight against corruption and the strengthening of the domestic market, as well as sexual freedom, which deeply moved Enrique, who attended the event waving the rainbow flag, which represents the LGBT community.

"The most important thing is the composition of the people congregated here because it represents the people of Mexico," Enrique told EFE, describing the triumph as a "victory years in the making."
