History

Ann [662]3 years ago

New scientific knowledge helped the building of the Panama Canal, as fewer workers got sick from malaria and yellow fever.

The discovery that yellow fever was transmitted by mosquitoes was made in 1891, but most sanitary officials didn't know or didn't give relevance to it.

However, captain William Gorgas did know about this and successfully helped to eradicate yellow fever and malaria in the Canal Zone, despite the opposition from U.S. officials who wanted to discredit his work.

President Theodore Roosevelt supported Gorgas and the Panama Canal was completed by 1914.

What were some of the issues/events that led<br> to the Civil war ?
just olya [345]

Answer:

Harriet Stowe's book,"Uncle Tom's Cabin," Missouri Compromise, Dred-Scott court case, the Fugitive Slave Act

Explanation:

1. Stowe's book greatly influeced the Civil War because she describes the true horrors of slavery that most northerners or other people, weren't very aware of. People knew slavery exsited, but didn't know how bad the treatment was. This open the eyes for the people in the North especially, increasing the amount of people to support anit-slavery.

2.The Missouri Compromise is what starts is all, by diving the U.S. into slave and free states, there was bound to be created tensions between the two sides.

3.The Dred-scott case ruled that slaves were property and did not have any rights to the Consitution...this was a shocked factor to both free and slaved blacks. Once again, fueling tensions between anti-slavery, and pro-slavery people.

4. Th Fugitive Slave Act angered many Northerns who were anti-slavery because, the act forced northerners to capture and return any slaves that escaped to the North. They can't help them to escape, otherwise they will be jailed, which goes against Northerns morals. This act mainly favored the South.
