The correct answer to this open question is the following.
Although you did not attach options for this question we can comment on the following.
The consequences of political and nationalistic revolutions were the following.
These armed movements started when people got tired of the tyrannic ways of their kings and the excessively luxurious ways the monarchs lived in when poor people and peasants were hungry and dying of starvation.
Another important factor was a sense of nationalism and the love for their nation, repelling external influences that did not fit well in a determined culture. Some countries did not want to be unified with other countries. This factor created many ethnic differences and struggles. Finally, another important reason was liberal ideas that started to be considered by political leaders that harangued people with ideas of liberty and sovereignty.
The best example to support these concepts is the European Revolutions of 1848.
