How did life change for the indigenous people after the arrival of the Portuguese?

The lives of the indigenous people of Brazil, the region of the Americas where the Portuguese landed, changed radically after this event.

Explanation:

For one, the vast majority of them perished (around 90%) due to the spread of contagious Eurasian diseases like measles or viruela, for which they did not have immunity.

The few who survived were subjected to slavery at first, and when the Catholic Church prohibited the enslavement of Native Americans, to serfdom, and brutal working conditions.

They were also stripped of their lands and property, and were given very few opportunities to climb up the social ladder in the colonial Brazilian society.

in mcculloch v. maryland (1819) the supreme court ruled that congress had implied powers under the necessary and proper clause of article i, section 8 of the constitution to create the second bank of the united states and that the state of maryland lacked the power to tax the bank.

gibbons v. ogden, (1824), was a landmark decision in which the supreme court of the united states held that the power to regulate interstate commerce, granted to congress by the commerce clause of the united states constitution, encompassed the power to regulate navigation.
