What year did the drinking age change from 18 to 21?

In the early 1980s, the group managed to attract attention from the United States Congress. At a time when alcohol consumption laws varied greatly by state, New Jersey Senator Frank Lautenberg was a notable early supporter. Lautenberg took exception to the fact that youth in New Jersey could easily travel into New York to purchase alcoholic beverages, thereby circumventing New Jersey's law restricting consumption to those 21-years-old and over. The group had its greatest success with the imposition of a 1984 federal law that required states to raise the minimum legal age for purchase and possession (but not the drinking age) to 21 or lose federal highway funding. After the United States Supreme Court upheld the law in the 1987 case of South Dakota v. Dole, every state capitulated.
