Answer: the size of the crowd that attended
Step-by-step explanation:
The aspect of the march on Washington that sent a powerful statement to the United States and the world was the size of the crowd that attended. On August 28, 1963, around 250,000 people assembled in front of the Lincoln Memorial in Washington, D.C. The location at the Lincoln Memorial was already known as an area where public demonstrations were held. And the presence of religious leaders and famous celebrities, such as actors Ossie Davis and Ruby Dee and artists Marian Anderson, Joan Baez, Bob Dylan, and Mahalia Jackson, was important but not the main element that made the event known worldwide.
