stich3 [128]

✅​La doctrina fue presentada por el presidente Monroe durante su sexto discurso al Congreso sobre el Estado de la Unión. Fue tomado con dudas, al principio, y luego con entusiasmo.

La doctrina fue concebida por sus autores, en especial John Quincy Adams, como una proclamación de los Estados Unidos de su oposición al colonialismo en respuesta a la amenaza que suponía la restauración monárquica en Europa y la Santa Alianza tras las guerras napoleónicas.✅

Saint-Domingue (Haiti) was prosperous because of revenue earned from
Rasek [7]

Answer:

Saint-Domingue (Haiti) was prosperous because of revenue earned from sugar.

Explanation:

When the Europeans came to Haiti, the native people lived in a simple way and were relatively isolated from their surroundings, let alone the world. The Europeans though thought that this place has big potential, especially in farming. What the Europeans had on mind was to create large plantations with sugar cane, thus produce sugar and make a profit out of it.

While the Europeans were not many in number, and the native population was decimated, a lot of African slaves were brought as a labor force for the plantations. The wet tropical climate enabled high-scale production of sugar cane, and with sugar becoming increasingly popular and being paid well for, the Europeans earned a lot from the trade. Haiti actually became a very prosperous island, and that was strictly down to the production of sugar cane and sugar from it.
