The Berlin blockade was performed by the URSS in 1948 and lasted for approximately one year.
The city of Berlin had been divided in four sectors, exactly in the same manner that the whole German territory was divided and splitted among the victorious Allied countries after WWII. US, UK and France unified their territories and created the Federal Republic while URSS created the German Democratic Republic on the Eastern the side, which remained independent from the other three . The city of Berlin was divided in four as well, but the city was actually embodied within the Eastern region of Germany under the control of the Soviet Union.
<u>This is why the URSS could block supplies and impede ground communications with West Berlin, the area of the city controlled by US, UK and France. The so-called Berlin airlift was organized </u>to acess this area of the city by plane, in order to bring supplies.
Great Britain increased its control over the colonies by creating various of acts on the colonists. As such they placed taxes (a.k.a Custom Duties and Tariffs: any tax on imported and exported goods) on certain things. An example of the most known act was the Tea Act. The Tea Act was to tax any tea items. Because the colonists were getting taxed so much before the Tea Act, the Boston Massacre occurred where the colonists disguised themselves, boarding the ship and dumping chests of tea into the water. Thus, Britain created the Coercive Act, preventing the actions of colonists and banning the Massachusetts's port until they paid for it, expanding their powers.
