Americans have observed the holiday, Veterans Day, on Nov. 11 since 1919, a year after fighting ended in World War I.

Originally known as Armistice Day, the holiday was later expanded after World War II to celebrate all U.S. veterans. On this special day, Hollywood paid tribute on social media to the many veterans who have served our country and protected our rights.

"Thank you for serving our country with courage and dedication. God bless all of you and your families," actor Mark Wahlberg wrote on Instagram alongside an American flag. 

"Today and every day #thankyouforyourservice #veteransday," said Oscar-winner Matthew McConaughey while posing with a group of soldiers.
