During the vietnam war, what voting rights were changed by the 26th amendment?

Context/details:

Faster means of communication pushed the progress of the 26th Amendment.  This was seen in the protest movements going on during the 1960s, leading up to 1971 when the 26th Amendment was passed by Congress and ratified by the states.  Protests against the Vietnam War were active on college campuses across the country, with communication between students and media reports being a big part of the story.  Part of those protests were the demands of young people chanting, "Old enough to fight, old enough to vote."  Since 18 was old enough to be drafted to fight in the war, young people argued for their right to vote as full citizens.

The 26th Amendment was passed by Congress on March 23, 1971.  It was ratified by the states faster than any other amendment, achieving ratification by July 1, 1971.

The 26th Amendment is worded as follows:  

john locke is most associated with the idea of consent of the governed which is the idea that the government is only valid if it has the consent of the people who are being governed.
