10. Why did many African Americans leave after the revolutionary war?

Explanation:

The Revolution had contradictory effects on slavery. The northern states either abolished the institution outright or adopted gradual emancipation schemes. In the South, the Revolution severely disrupted slavery, but ultimately white Southerners succeeded in strengthening the institution.

After the American Revolution, many colonists—particularly in the North, where slavery was relatively unimportant to the agricultural economy—began to link the oppression of enslaved Africans to their own oppression by the British, and to call for slavery's abolition.

The Blacks who fled to the side of the British did not risk their lives because of loyalty to the Crown. They did so in order to gain their freedom and pursue their vision of equality and justice in a territory where the slave trade had been abolished.

the captain of a steam ship naturally chooses the shortest route to his destination. since a sailing ship is usually pushed by winds and currents, its captain must find a route where the wind will probably blow in the right direction. tacking, i.e. using contrary wind to pull (sic) the sails, was always possible but wasted time because of the zigzagging required, and this would significantly delay long voyages. the early european explorers were not only looking for new lands. they also had to discover the pattern of winds and currents that would carry them where they wanted to go. during the age of sail winds and currents determined trade routes and therefore influenced european imperialism and modern political geography. for an outline to the main wind systems see global wind patterns.

pilotage or cabotage, in one sense, is the art of sailing along the coast using known landmarks. navigation, in one sense, is the art of sailing long distances out of sight of land.[1] although the polynesians were able to sail the pacific (with great difficulty) and people regularly sailed north and south across the mediterranean, before the time of columbus nearly all sailing was coastal pilotage
