Explanation:

The Black Plague was originated from Asia and was brought to Europe through the Silk Road in the 14th century. In this period, Europe was emerging to an urban continent after centuries of feudalism. However, cities were small, without any hygiene treatment and the people were unaware of the necessity of cleaning themselves. Because of that, when the plague arrived, it founds a good place to spread. The period between 1347 to 1351 is considered the peaking of the plague, killing 20% to 60% of the population, which equals to a third of the population.

in griswold v. connecticut (1965), the supreme court ruled that a state's ban on the use of contraceptives violated the right to marital privacy.
