Argentinian students force university reforms, 1918
Increased prosperity and the expansion of electoral rights at the turn of the century in Argentina precipitated significant growth in the middle class, a population shift with the majority now living in urban centers, and broader enrollment in universities, as newly prosperous families were able to send their children into higher education. The universal suffrage law of 1912 (granted to men over 18) was first applied in 1916, when Hipolito Yrigoyen of the Radical Party was elected with support from the middle and working class.
