Starting on March 19, 2003, a coalition consisting of US, UK, Australian, and Polish soldiers began bombing Iraq, followed by a ground invasion the next day.
Two decades later, the effects of the lengthy war that ensued are still visible in some parts of Iraq.
The United States, under former President George W. Bush, led the coalition of the willing into Iraq, resulting in the deaths of hundreds of thousands of Iraqis from 2003 to 2011.
When the coalition forces departed, they left behind a nation struggling with instability and sectarian conflict.
On Monday, on the 20th anniversary of the US invasion, numerous individuals took to social media to commemorate the US occupation of the Muslim country.
