The dedication ceremony of George W. Bush's presidential center has ended after the nation's 43rd president gave a closing speech with tears welling in his eyes.

A crowd of 10,000 watched as a military guard carried a line of flags off the stage, followed by the departure of all five presidents and their wives Thursday in Dallas.

The ceremony was also attended by former members of the Bush administration, including former Secretary of State Condoleezza Rice, current and former world leaders including former British Prime Minister Tony Blair and the children of former presidents.

Bush gave the last speech, noting his joy that his father, the 41st president, was able to attend the dedication.

He said, "41, it is awesome that you are here today."
