The 23rd Amendment to the United States Constitution was adopted on March 29, 1961 and granted citizens of Washington, D.C., the right to vote in presidential elections. The amendment was a response to the lack of voting rights for residents of Washington, D.C., who had no representation in the Electoral College despite paying federal taxes. This was seen as an unjust denial of their constitutional right to vote, and thus the amendment was proposed to rectify this issue. The 23rd Amendment was ratified by the required number of states on March 29, 1961 and became a part of the Constitution.
