As the oldest civil rights organization in the country, NAACP leaders said they are convening in Houston at a historic and critical time for it's members.
More than 5,000 people are registered to attend the convention and will focus on issues like education, health care, voting and the November election.
Republican presidential candidate Mitt Romney is scheduled to speak on Wednesday, followed by Vice President Joe Biden on Thursday.
The convention book clearly touts a keynote speech from President Barack Obama, but, according to organizers, he will not be able to attend the events.
Organizers said they continue to rally attendees to fight against voter suppression efforts across the country. They said legislation, like proposed voter identification laws, could keep some elderly and minority voters away from the polls.
U.S. Attorney General Eric Holder is also scheduled to speak at the convention next week.
