Answer:
Valuable goods like cotton were essentially the main drivers of conflict between European Countries in the Americas.
The reason why European Countries established colonies in the Americas in the first place was to obtain valuable goods that could only be produced or found there: goods like cotton, rice and sugarcane.
The possession of territories were these goods were produced often resulted in armed conflict. The French-Indian war, which occurred two decades before the American Revolution, is an example.
Answer: Because it showed that change is possible
Explanation/context:
The medieval era had been one in which the Roman Catholic Church dominated the culture of Europe, and it was thought that no one could successfully challenge such a deeply ingrained institution. However, the Reformation movement by Martin Luther and other Protestant figures showed that even something as entrenched and enduring at the Catholic Church could be challenged, and changes could be accomplished. Even during Martin Luther's lifetime, this idea that change was possible motivated people to launch efforts toward other major changes to powerful systems. The Peasants Revolt that occurred in Germany in 1524-1525 took Luther's push for reform in the church and applied it to make a push for change in feudal society. Martin Luther himself didn't agree with that and opposed the Peasants Revolt, but as Schaff points out, the momentum of the Reformation was a "propelling force" inspiring other "forward movements" to make changes in society.
The Libertarian party is highly against government interventionism and believes that wars should be fought only and only if attacked first, as self defense.
