Grenada
Though the model was copied from the United States, Grenadians celebrate Thanksgiving Day for a rather very interesting reason.
After former Prime Minister Maurice Bishop was ousted from power in a coup supported by his Deputy Prime Minister Bernard Coardon on October 16, 1983, and subsequently executed, the United States with the support of allied Caribbean forces invaded the country on October 25 of the same year and seized control.
Though their actions were widely criticized internationally, Grenadians were actually grateful.
Observed annually as a national holiday on October 25, Thanksgiving is actually held in Grenada to show gratitude to the United States for the invasion and is also observed as a remembrance day.
