What does “DC” Mean?

When you come to the convention, you’re going to notice that most people refer to the area as “DC”, and you should too. This stands for District of Columbia, named after Christopher Columbus whose voyages to the Americas ignited Europe’s interest in the new world.

In 1791, three commissioners appointed by then President George Washington named the area destined for the seat of the U.S. government “the Territory of Columbia”; it was subsequently (1801) organized as the District of Columbia.
