Do you think one-party rule or divided government comes closer to the ideal the framers had when they envisioned a government without political parties

Answers

Divided government likely comes closer. At the founding of the country, there were already divisions in ideas and ideals, such as the Federalists and Anti-Federalists. Having differences in ideas on how to best run the government gives the ability to see problems from multiple angles and look for the most equitable solutions.

The framers did not anticipate political parties, but designed a system to prevent factional dominance, which divided government embodies. However, divided government also complicates governance and dilutes accountability, deviating from the ideal of efficient government serving the common good.

Constitution envisioned, it's important to note that the framers did not anticipate the rise of political parties. Concerns expressed by early leaders like George Washington highlighted the potential dangers of factions, suggesting an intent for a government that promotes the common good over partisan interests. The framers feared political parties could lead to despotism and division among the populace. However, the system they created with separation of powers and checks and balances unwittingly allowed for the rise of such parties.

Divided government can be seen as both a realization of the framers' intent to prevent any one group from wielding excessive power, but also as an impediment to clear accountability and effective governance. It fosters conditions where fulfilling campaign promises becomes difficult due to the need for cooperation between the president and a Congress that may be controlled by the opposing party. Conversely, one-party rule can arguably facilitate unified action and clearer accountability, yet it may also lead to the type of faction dominance that early leaders like Washington warned against.

The framers might not have envisioned a government without political parties, as parties naturally formed out of the political divisions of their time, but the spirit of their concern was focused on inhibiting any one faction from obtaining too much power, while also ensuring that the government could effectively realize the common good without being hindered by partisan politics.

In the 17th century, what political conditions accounted for the increased power of both parliament in england and the monarchy in france

Answers

Final answer:

In the 17th century, both Parliament in England and the monarchy in France gained increased power due to political conditions.

Explanation:

In the 17th century, both Parliament in England and the monarchy in France gained increased power due to political conditions.

In England, the Hundred Years' War resulted in a stronger role for Parliament, as funds were needed to fight the French. This led to the development of a representative government.

In France, the war helped forge a common identity among the French people, but regional assemblies did not want to give up their power. As a result, France built its national government on a strong monarchy.

The period was one of contrast, with the excitement of new entertainment forms and the underlying conflicts of a rapidly changing society.

Explanation:

Famous Names and Historical Events of the 1920s

The 1920s, often referred to as the Roaring Twenties or the Jazz Age, was a decade of profound social, economic, and cultural transformation in the United States. The era is known for its sports legends, entertainment milestones, and significant societal shifts. Babe Ruth dominated baseball, becoming an American icon with his remarkable home run record. Meanwhile, Jack Dempsey became a symbol of might in the world of boxing, and football star Red Grange captivated fans with his athleticism.

Technological advancements, like the rise of radio, allowed sports heroes to reach unprecedented levels of fame. Jazz music evolved during this time, laying a foundation for modern music genres and was central to the nightlife especially in Harlem nightclubs. The literary works captured the spirit of the times, often reflecting the Lost Generation and the Harlem Renaissance. Notably, the decade saw tremendous economic growth but ended with the onset of the Great Depression.

The clash between traditionalism and modernism was also evident, with rapid urbanization catalyzing changes in societal norms and values. This period gave rise to consumer culture, as mass production and advertising became more pronounced. Despite the outward appearance of endless parties and prosperity, as depicted in F. Scott Fitzgerald's literature, it was also an era of deep conflict and the eventual financial collapse with the stock market crash of 1929.

What were the puritans main fears and anxieties?

Answers

The Puritans feared what they could not explain, especially unexplainable things in the Bible. They also feared famine, insurrection and diseases. They commonly feared Satan, the devil, who they believed was everywhere. But, most especially, they fear God. Due to their belief that the devil was everywhere, trying to destroy them, Puritans became more paranoid and superstitious.

The Puritans, a strict gathering that arose in Britain during the late sixteenth and seventeenth hundreds of years, held a few feelings of dread and tensions that impacted their convictions and activities.

Here are a portion of their primary worries:

The Puritans confronted abuse and separation from the laid out Chapel of Britain, which they accepted was defiled by leftovers of Catholic practices. They expected that their strict opportunities would be shortened, prompting the suppression of their convictions and practices.

The Puritans were profoundly worried about what they saw as the ethical rot of society. They dreaded the spread of corrupt ways of behaving, like tipsiness, betting, and indiscrimination, which they trusted undermined the texture of their networks.

The Puritans had faith in the truth of black magic and considered it to be a sign of fiendishness. They expected that witches, who were accepted to have made a settlement with Satan, would ruin the genuine local area and carry mischief to people.

Read an excerpt from President Wilson’s speech asking Congress to declare war on Germany.

It is a fearful thing to lead this great peaceful people into war, into the most terrible and disastrous of all wars. But the right is more precious than peace, and we shall fight for things which we have always carried nearest to our hearts—for democracy, for the right of those who submit to authority to have a voice in their own Governments, for the rights and liberties of small nations, for universal dominion of right by such a concert of free peoples as shall bring peace and safety to all nations and make the world itself at last free.

What is the main reason the United States entered the war, according to Wilson?

Wilson believed that without American involvement, Germany would surely win the war.

Wilson believed that war is near to the hearts of the American people.

Wilson believed that the United States is determined to protect democratic ideals.

Wilson believed that the United States needed to force Germany to submit to American authority.

Answers

Wilson believed that the United States is determined to protect democratic ideals. This can be seen through the statement in his speech declaring that, "we shall fight for things which we have always carried nearest to our hearts - for democracy."

The correct answer is "Wilson believed that the United States is determined to protect democratic ideals".

Regardless of who would win or which country's authority prevails after a battle, what Wilson is talking about is ideals. What the American people should carry nearest to their heart isn't war either but the determination to protect democracy at whatever cost.

He recognizes it's dreadful to disrupt the lives of the peaceful population bringing them into the horrors of war, but to him, the right to democracy is more precious than peace itself.

Taxes went up, and the gap between the rich and poor increased.

Explanation:

A value roof was set for meat, grain, eggs, apparel, and different merchandise, and organized capital punishment for any individual who sold their products at a more expensive rate than what was built up.

Rome had turned into an authoritarian express that accused monetary issues for the backs of assumed narrow minded profiteers. The outcome, as it ought to be, was that individuals just quit putting their products available, as they could never again get a reasonable cost for them.

Traders amassed their merchandise, declining to offer them at the legislature forced cost. Others loaded basically so as not to risk being wrongly blamed for selling at above-estimated costs and subsequently being exposed to dispossession. The workers responded to the solidifying of wages vanishing from the file or just lounging around, doing nothing.
