Answer:
Why did so many Germanic tribes begin invading the Roman Empire? They were fleeing the Huns, who had moved into their lands and began destroying everything. When they were running away from the Huns, the Germanic people moved through the Roman provinces of Gaul, Spain and North Africa.
Explanation:
Gorbachev pursued glasnost and perestroika reforms in part because the war in Afghanistan had drained the nation's resources. Mikhail Gorbachev, as known as the former General Secretary of the Soviet Union (Russia), noticed that there has been a huge decrease in their resources. They were fighting a war in Afghanistan, and used all of the nation's resources to help them win the war. Since they used most of their resources, they didn't have much to help the economy, so if they don't get enough resources back, the economy would fail. Because of this Gorbachev made a movement called "perestroika" to help get back the nation's resources. What this movement did was let the government speaker, or have a conversation, about the issues that are going on in the economy, and see if there could be a way to solve it.
