Answer:
Turkey Day Football
The first ever Thanksgiving Day football match was between the teams from Yale and Princeton Universities.
Explanation:
Historically, the Pilgrims commenced US Thanksgiving celebrations in 1621, following the England custom. Abraham Lincoln proclaimed a national holiday for Thanksgiving Day in 1863. The first ever football game on a Thanksgiving Day took place in Philadelphia in 1869. This was six whole years after Thanksgiving Day was declared a national holiday.
It was forgotten in it's time because no one cared about being civil and listening to what EVERYONE wanted and being at peace with one another. They thought fighting in a war would help them simmer their dispute. Today, we don't fight over lands and things as much as we used to. While South America and North America are still fighting, *not in a huge war* it's not the same as it was then.
