Who was the pro-states vide president?

Answers

Explanation: President Pro Tempore

The Constitution provides for a president pro tempore to preside over the Senate in the absence of the vice president. Except for the years from 1886 to 1947, the president pro tempore has been included in the presidential line of succession. Following passage of the Presidential Succession Act of 1792, the president pro tempore was next in line after the vice president, and followed by the Speaker of the House of Representatives. In 1886 a new law removed the president pro tempore and the Speaker from the line of succession, substituting cabinet officers. A 1947 law changed the order of succession to place the Speaker of the House in line after the vice president, followed by the president pro tempore, and then the secretary of state and other cabinet officers in order of their departments' creation. This is the system in effect today.

Should we follow a popular system or the electoral college system when deciding the presidency?

Answers

Answer:

The United States Electoral College is the group of presidential electors required by the Constitution to form every four years for the sole purpose of electing the president and vice president. Each state appoints electors according to its legislature, equal in number to its congressional delegation. Federal office holders cannot be electors. Of the current 538 electors, an absolute majority of 270 or more electoral votes is required to elect the president and vice president. If no candidate achieves an absolute majority there, a contingent election is held by the United States House of Representatives to elect the president, and by the United States Senate to elect the vice president.

The Christian Crusaders answered the call to journey to Jerusalem hoping to "earn forgiveness for their sins from the Church."

Who are the Crusaders?

The term Crusaders is used to define the people who have participated in the military expeditions undertaken by the Christian powers between the 11th, 12th, and 13th centuries.

The expeditions are undertaken with a view to winning the holy land from the Muslim powers.

On June 7, 1099, the Christian army reached the holy land of Jerusalem. There were 1,200 cavalry and 12,000-foot soldiers who completed the journey. The journey was seen by them as a journey to earn forgiveness for their sins from the Church.

What happened on September 11, 2001, and how did the George W. Bush administration respond in both domestic and foreign policy?

Answers

Answer:

The United States invasion of Afghanistan occurred after the September 11 attacks in late 2001 and was supported by close US allies. ... US President George W. Bush demanded that the Taliban hand over Osama bin Laden and expel al-Qaeda; bin Laden had already been wanted by the FBI since 1998

Explanation:

The most significant economic impact of the 9/11 attacks was how the increased defence spending led to the U.S. debt crisis. Without the War on Terror, the 2020 debt would be $20 trillion or less. That's $26 trillion total debt, at present, minus $6 trillion

Answer:

On September 11th, 2001, a terrorist attack was undertaken against the world trade center wherein aircraft were flown into both towers, resulting in a bifold collapse of the structures with many civilians still inside. This, added to the death toll of emergency responders in the wake of the collapse, awoke mass outcry.

The Bush administration responded by starting a "War on Terror" which rages on today, and security measures in transit regions like airports were massively increased in scope.

What did the Homestead Act declare (say)? Explain any issues people may have had with it?

Answers

Answer:

The Homestead Act, enacted during the Civil War in 1862, provided that any adult citizen, or intended citizen, who had never borne arms against the U.S. government could claim 160 acres of surveyed government land. Claimants were required to “improve” the plot by building a dwelling and cultivating the land.

The biggest problem with the Homestead Acts was the fact that the size of the homesteads — 160 acres — was far too small to allow for the landowners to succeed as independent farmers.
