Why did jefferson use the u. s. navy against north african states? - the barbary pirates held american merchant ships hostage and jefferson sent in the navy rather than pay the ransom. - jefferson wanted to disarm the pasha of tripoli, who had gathered weapons he planned to use against the united states. - plantation owners wanted to import more africans before the international slave trade became illegal in 1808, and they needed american firepower to them do it.

Tripoli had declared war on the United States after Jefferson had refused demands for increased payments to the Barbary pirates.

when studying cause and effect, historians usually group the causes into different categories. for example, cultural causes reflect how a society’s literature and art convey the way the society saw itself in relation to the rest of the world. another resource that historians use to understand society is pop culture, which tells them the trends and ideas that are preferred by the common people. when studying cause and effect, it’s important to remember multiple causation, or the idea that an effect could have several causes and vice versa.
