The Obama era is over—but it left behind some pretty great photos.

After eight years in office, President Barack Obama exited the White House on Jan. 20, closing the latest chapter in American history to make way for the next.

The Obama presidency was one of wild swings in American life, from the devastating recession that overshadowed his inauguration in January 2009 to the divisive 2016 election that chose his predecessor, President Donald Trump. Throughout it all, White House photographer Pete Souza (and a few of his colleagues) were there to capture some of the most historic points in Obama’s eight years in office.

Below, we’ve gathered a large collection of photos from Obama’s time in office, from simple moments to historic ones. These photos are but a handful of the hundreds posted online by Souza, and we recommend exploring his best shots, which you can find linked on each year below.

Here is the Obama presidency, in photos, with captions from Souza to guide you through the eight years in America before Trump took charge.

Some more background on the photograph: The White House Situation Room is actually comprised of several different conference rooms. The majority of the time, the President convenes meetings in the large conference room with assigned seats. But to monitor this mission, the group moved into the much smaller conference room. The President chose to sit next to Brigadier General Marshall B. “Brad” Webb, Assistant Commanding General of Joint Special Operations Command, who was point man for the communications taking place. With so few chairs, others just stood at the back of the room. I was jammed into a corner of the room with no room to move. During the mission itself, I made approximately 100 photographs, almost all from this cramped spot in the corner. There were several other meetings throughout the day, and we’ve put together a composite of several photographs (see next photo in this set) to give people a better sense of what the day was like. Seated in this picture from left to right: Vice President Biden, the President, Brig. Gen. Webb, Deputy National Security Advisor Denis McDonough, Secretary of State Hillary Rodham Clinton, and then Secretary of Defense Robert Gates.
