Term limits are also common in Latin America, where most countries are also presidential republics. Early in the last century, the Mexican revolutionary Francisco Madero popularized the slogan "Sufragio Efectivo, no Reelección" (effective suffrage, no reelection). In keeping with that principle, members of the Congress of Mexico (the Chamber of Deputies and Senate) cannot be reelected for the next immediate term under article 50 and 59 of the Constitution of Mexico, adopted in 1917. Likewise, the President of Mexico is limited to a single six-year term, called the Sexenio. This makes every presidential election in Mexico a non-incumbent election.
