The parliament became stronger and limited the monarchy in order to end absolutism in England.
While you didn't really provide the "following" as the comment above me states, in general, the advantage of secondary sources of primary ones is that they perhaps provide a more objective or even just a broader view on a certain topic. While a primary source of the American civil war would be a letter written by a soldier, a secondary source would be a book that describes more letters taken together and discusses possible information regarding them.
What time period are you focusing on?
George Washington was the first president of the United States in April of 1789
Answer:
The Kansas-Nebraska Act was an 1854 bill that mandated “popular sovereignty”–allowing settlers of a territory to decide whether slavery would be allowed within a new state’s borders. Proposed by Stephen A. Douglas–Abraham Lincoln’s opponent in the influential Lincoln-Douglas debates–the bill overturned the Missouri Compromise’s use of latitude as the boundary between slave and free territory. The conflicts that arose between pro-slavery and anti-slavery settlers in the aftermath of the act’s passage led to the period of violence known as Bleeding Kansas, and helped pave the way for the American Civil War (1861-65).
This 1854 bill to organize western territories became part of the political whirlwind of sectionalism and railroad building, splitting two major political parties and helping to create another, as well as worsening North-South relations
