While the first Thanksgiving was held in 1621, it would take more than 150 years before all 13 colonies celebrated Thanksgiving at once, in October 1777. In 1789, George Washington hailed the holiday, while President Thomas Jefferson scoffed at the notion, calling Thanksgiving "the most ridiculous idea" ever conceived. For his part, Benjamin Franklin had such an affinity for turkey that he lobbied to make it the national bird (to no avail).
