Dallas is a large city in the northern part of the U.S. state of Texas. It is a part of a much larger group of cities called the Metroplex, along with important cities like Arlington, Mansfield, Grand Prarie Denton, Fort Worth, and Plano. The city is the ninth largest in the United States.
For many years, the city was known as the city in which President John F. Kennedy was killed, but that is not associated with the city as much anymore.
