James Monroe was the 5th president of the United States. he was the last president who was a Founding Father of the United States, third of them to die on Independence Day and the last president from the Virginia dynasty and the Republican Generation. He died on July 4 1831.
There is a difference between what being a "founding father" is, and being a framer of the constitution, as there were some of our founding fathers who were not at the Convention when the Constitution was formed.
Many historians consider Andrew Jackson a Founding Father because he was in the revolutionary war as a child. He was also one the first presidents. I do not consider him to be a founding father however.
