Question: In the early 20th century, describe how life for black people was different in Vienna,Australia compared to life in the United States
Answer: The nineteenth century was a time of radical transformation in the political and legal status of African Americans. Blacks were freed from slavery and began to enjoy greater rights as citizens (though full recognition of their rights remained a long way off). Despite these dramatic developments, many economic and demographic characteristics of African Americans at the end of the nineteenth century were not that different from what they had been in the mid-1800s. Tables 1 and 2 present characteristics of black and white Americans in 1900, as recorded in the Census for that year. (The 1900 Census did not record information on years of schooling or on income, so these important variables are left out of these tables, though they will be examined below.) According to the Census, ninety percent of African Americans still lived in the Southern US in 1900 — roughly the same percentage as lived in the South in 1870.
The Native Americans didn’t have as strong weapons or armor, they also didn’t have immunity to the diseases that the Europeans brought over as carriers.
In short:
Their simple weapons couldn’t pierce metal armor and then their population was drastically decreased through means of accidental biological warfare.
