A. rise of nationalism in Europe after the defeat of Napoleon
Explanation:
"SPRING OF THE PEOPLE" or as this period is called "THE YEAR OF REVOLUTION" is the period when Europe was swept up by the widest wave of revolutions.
More than 5 states were affected, but there was no coordination or cooperation among revolutionaries from different states.
The causes of these events should be sought in the earlier period of 1814-1815, when at the Congress of Vienna the powerful decided to return power to the hands of the established rulers. This meant the formation of a "Holy Alliance" tasked with militarily suppressing revolutions and protests in Europe. Based on this decision, France becomes a monarchy again, and it ceases to be a republic.
In 1848, a revolutionary wave began in France in February, and immediately spread to most of Europe.
Supreme Court decision maintains that seditious speech -- including speech that constitutes an incitement to violence--is protected by the 1st Amendment to the US Constitution as long as it does not indicate an imminent threat.
