On January 20th, Barack Obama will officially begin his second term as President of the United States. Over the past four years as one of the most visible Presidents in history, we have witnessed nearly every day of the President's life in office. Thanks to the efforts of Pete Souza (Chief Official White House photographer for President Barack Obama and Director of the White House Photography Office) and others, we have been able to share the laughs and tears and gain a personal relationship with Barack and the entire First family.

To recap some of those moments and prepare for four more years, we bring you The 25 Most Iconic Photographs From Obama's First Term.
