Answer:
The Brandenburg Gate Speech, delivered on June 12, 1987 by President Reagan, was the most significant speech at the end of the Cold War. There, President Reagan addressed Mikhail Gorbachev, the leader of the Soviet Union, directly, asking him directly to tear down the wall that separated East Germany from West Germany, thus ending the separation of both parts of the city of Berlin. But this speech had behind it a much deeper ideological baggage, in which President Reagan urged the Soviet Union to cease its actions and surrender, given the demonstrated inability to maintain communism on a global scale that the Soviets had demonstrated.
Thus, 2 years later, the wall was demolished and the German reunification took place, being one of the final episodes of the Soviet defeat in the Cold War.
Spain found missions and presidios A. to convert American Indians to Christianity, and C. to teach American Indians how to live as Spanish colonist.
It was a way to try that the Indians become sedentarian in the frontier of the Empire. The missionaries often learnt about the Indian culture in order to teach them Christianity in a way they would understand, but it was a non-planned effect of the establishment of missions. I any case they would want the Indians to become soldiers, because they might have turned against them.
The Battle of the Little Bighorn, fought on June 25, 1876,
near the Little Bighorn River in Montana Territory, pitted federal
troops led by Lieutenant Colonel George Armstrong Custer (1839-76)
against a band of Lakota Sioux and Cheyenne warriors. Tensions between
the two groups had been rising since the discovery of gold on Native
American lands. When a number of tribes missed a federal deadline to
move to reservations, the U.S. Army, including Custer and his 7th
Calvary, was dispatched to confront them. Custer was unaware of the
number of Indians fighting under the command of Sitting Bull (c.1831-90)
at Little Bighorn, and his forces were outnumbered and quickly
overwhelmed in what became known as Custer’s Last Stand.
This is true because even if that grandparent was to change from Jewish to Christianity they would still be considered Jewish and the Nazis thought it was passed down to the grandchildren.
