This Sept. 18, 2015 photo shows the Iroquois Nationals lacrosse team line up prior to competing in the 2015 World Indoor Lacrosse Championships on the Onondaga Nation just south of Syracuse, New York. The Ireland Lacrosse team recently bowed out of the sport's top international tournament to open up a spot for the Iroquois Nationals. It's the latest in a series of gestures between the country and U.S. tribes that date back to 1847, when Choctaw leaders gave $170 to the Irish as their country battled a potato famine that resulted in the death of tens of thousands. Historians estimate today's value of the amount at roughly $5,000. (Jourdan Bennett-Begaye/Indian Country Today via AP)
