what were the ideals associated with the Enlightenment how did these ideals pave the way for revolutions

Answers

Answer 1

Individualism, liberty, and autonomy challenged the roles of church leaders and monarchs. In Europe in the 18th century, a philosophical movement known as the Enlightenment, also known as the Age of Enlightenment, dominated the world of ideas.

It planted the seeds of revolution in the United States, France, and elsewhere. Liberty, progress, tolerance, fraternity, constitutional government, and the separation of church and state were among its guiding principles. The idea that reason is the most important source of authority and legitimacy was at the center of it. The Enlightenment was characterized by an emphasis on the scientific method and reductionism, in addition to raising more questions about religious orthodoxy. The ideas of the Enlightenment made the monarchy and the church less powerful and made it easier for political revolutions in the 18th and 19th centuries. French historians claim that the Enlightenment typically took place between 1789, when the French Revolution began, and 1715, when Louis XIV died. Recent historians claim that the Scientific Revolution began in 1620. However, numerous national variations of the movement flourished between the first decades of the 18th century and the first decades of the 19th century.

What was the price of gas during World War 2?

Answers

The effects of World War II meant that Americans who owned vehicles in the 1940s had a limit on the amount of gasoline they could purchase long before the OPEC gas crisis of the 1970s.

Gasoline was seen as a valuable resource beginning in early 1942 and was required for the war effort to power our aircraft, tanks, Jeeps, and boats due to its restricted supply.

Franklin D. Roosevelt successfully reduced a number of consumer prices during World War II.

The American populace has never been expected to make even a small personal sacrifice during this spending binge. This stands in stark contrast to the rationing that we endured during World War II, although grudgingly.

What is the basic difference between Shi’ite and Sunnis?

Answers

Sunnis focus on following the Prophet's example, but  Shi'a focus on the lineage of Muhammad's family through a series of Imams.

Shi'ite Muslims and Sunni Muslims are the two largest branches of Islam, with the overwhelming majority of Muslims being Sunni. The main difference between the two branches is that Sunni Muslims consider the first four caliphs to be the rightful leaders of the Muslim community after the death of the Prophet Muhammad, while Shi'ite Muslims believe that the first caliph should have been Ali, the prophet's cousin and son-in-law. This difference in belief has led to some historical conflicts between the two branches, although the vast majority of Muslims today coexist peacefully regardless of their branch of Islam.

Radar, which could detect approaching enemy aircraft at a distance of 80 miles, was essential in providing air defenses with early notice of German raids during the Battle of Britain.

The CH stations were enormous, stationary structures with steel transmitter towers that rose above 100 meters. The radar enabled Britain to track approaching German aircraft, giving Sir Hugh Dowding's Fighter Command enough time to take off and engage them. The southeast of England was covered by a network of radar stations. The image up top depicts a German assault on the Dover radar facility in 1940. Radar provided advance notice of impending strikes.

When there was a serious shortage of pilots in the United States in 1942, the country's leaders took a chance on an experimental program to help fill the gap: training women to fly military aircraft so that male pilots might be released for combat duty abroad.

The Women Airforce Service Pilots, or WASP for short, was the name of the corps of female pilots.

About 2 million workers were on picket lines during the height of the strikes. Harry S. Truman attempted to put an end to the steel strikes by first negotiating with the union leaders and later taking over the coal mines. The Taft-Hartley Act, passed in 1947, gave states the authority to enact right-to-work laws that forbade "closed shop" agreements that kept non-union workers out of organised workplaces. Additionally, it gave the federal government the power to enjoin strikes that "jeopardised the public health or safety."

________ was the forerunner of the English Reformation, who objected to the pope's interference in English politics.

John Wycliffe was the forerunner of the English Reformation, who objected to the pope's interference in English politics.

John Wycliffe, also known as Wycliffe, Wyclif, Wicliffe, or Wiclif, was an English theologian, philosopher, church reformer, and promoter of the first English translation of the Bible. He was born around 1330 in Yorkshire, England, and passed away on December 31, 1384, in Lutterworth, Leicestershire. One of the pioneers of the Protestant Reformation was him. His political-ecclesiastical theories demanded that the church give up its material possessions, and in 1378, he began a systematic attack on the church's beliefs and practices. His controversial views were propagated by the heretical Lollards. In his political treatises on divine and civil dominion (De dominio divino libri tres and Tractatus de civili dominio), he argued that men exercised "dominion," which means possession and authority, directly from God and that their dominion was only apparent if they were in mortal sin. Even if they were not allowed to assert dominion, only the righteous could legitimately have it. He went on to say that the church should give up its possessions and return to evangelical poverty because it was in sin. He thought that the state, and particularly the king, should carry out this detachment.

How did Scotland get to where they are today 

Answers

Scotland has a long and complex history that has shaped the country into what it is today.

The earliest inhabitants of Scotland were Celtic tribes, who arrived around the 7th century BCE. In the 9th century, the Vikings began raiding and eventually settled in the country, forming the Kingdom of the Isles. In the 11th century, Scotland was united under the rule of King Malcolm III, and by the 13th century, it had become an independent kingdom.

Throughout the Middle Ages, Scotland struggled with conflicts with England, including several wars and invasions. In the 16th century, Scotland adopted Protestantism and formed a union with England in the 17th century, becoming part of the Kingdom of Great Britain.

In the 18th and 19th centuries, Scotland experienced significant industrialization, which transformed the country's economy and society. In the 20th century, there were calls for Scottish independence, and in 1997, a devolved Scottish Parliament was established with powers to legislate on certain domestic issues.

Today, Scotland is a country within the United Kingdom, with its own distinct culture, history, and identity. It has a thriving economy and is recognized internationally for its contributions to fields such as science, literature, and art.
