Bismuth is naturally occurring; bismuth oxychloride is not. The other problem with bismuth oxychloride is that it's a known irritant. It can cause itchiness, rashes and can even trigger acne breakouts in people with sensitive skin.ismuth oxychloride is a mineral, but it's not a natural one. It's a metal derivative, most commonly obtained as a byproduct of lead or copper smelting. It has been used in cosmetics for years to impart a shimmering glow.
Encomienda system established. The encomienda system was created by the Spanish to control and regulate American Indian labor and behavior during the colonization of the Americas. Under the encomienda system, conquistadors and other leaders (encomenderos) received grants of a number of Indians, from whom they could exact âtributeâ in the form of gold or labor.
Indians could no longer work in mines and on the land. Instead, a new system was introduced called the encomienda system. Under this system, the Indians were obliged to do a certain amount of work for the Spanish landowner on whose land they lived. It was not enough to keep up the output of the mines or the plantations. The local Indian labour had to be replaced. Enslaved Africans were brought in to do the hard labour of the new Spanish colonies. At first they were brought from other colonies owned by Spain, like the Canary Islands in the Atlantic Ocean.
