How has/does the amendment process enable/enabled society to grow and evolve?

In 1787, only white men over 21 could vote, and the President could serve for as long as he was elected! These Constitutional amendments changed those laws.

15th Amendment. This amendment, ratified in 1870, said that no citizen's vote could be taken away because of his race or color or because he was once a slave. In 1863, President Lincoln signed the Emancipation Proclamation, giving slaves their freedom. Nine years later this amendment gave citizens of all races the right to vote. It was a start in giving blacks full equality with whites.

19th Amendment. After this amendment was ratified in 1920, all women in the U.S. were allowed to vote. In 1787, men were always considered head of the household. Only they could vote. But women were becoming better educated. By 1848, they were working together to gain voting rights. Lawmakers were finally convinced 72 years later that women could vote as intelligently as men.

22nd Amendment. This amendment limits a president to two terms in office. George Washington started the presidential tradition of serving for two four-year terms. President Franklin Roosevelt, who was elected four terms in a row, was the first to break with this tradition. Many Americans thought that his four terms had allowed him to become too powerful. This national feeling helped get this amendment ratified in 1951.

26th Amendment. This amendment was passed in 1971, and it gave people 18 to 20 years old the right to vote. The national voting age had been 21. Eighteen-year-olds are old enough to join the U.S. armed forces. Many people think that this makes them old enough to vote for U.S. leaders, too. This amendment had widespread support. It was ratified in only four months.
