This is false. Since the soviet union broke and eastern Europe got destabilized, numerous wars were fought regarding ethnicity and religion. Many of them are still being fought today as some people don't have independence, while some fight because they want to control certain areas of the land.
It would be the aspect of "Joint Stock Companies" that was created by the Commercial Revolution and most clearly paved the way for today’s corporations, since this allows for large amounts of capital to be raised while "spreading out" the risk.
Actually, all of those answers were part of treaty agreements between the United States and Great Britain in 1817-1818.
The one that seems odd in the list is "Oregon Country disputed," because that was a matter not settled at that time. In the Treaty of 1818, the two sides agreed to some joint occupancy of the Oregon Country for ten years. Actual resolution of disputes over joint occupancy didn't come until the Oregon Treaty of 1846.
