The investiture Controversy or investiture Contest was a conflict between church and state in medieval Europe.. The investiture controversy began as a power struggle between pope Gregory VII and Henry IV, Holy Roman Emperor.
The Inca culture was one of the most developed in pre-Columbian America. Among their achievements, was their architectural ability. Inca structures were made of stone that fit together, with extraordinary stability. The buildings have survived for centuries, with no use of mortar, in areas that are prone to earthquakes and volcanic activity.
The Inca also developed calendars based on astronomical observations. Astronomers understood equinoxes, solstices and zenith passages. Numerical information, particularly for administration, was stored in <em>quipu</em> strings.
In terms of art, Inca ceramics were highly advanced, although most of their silver and gold work was melted down by the Spaniards.
They were also advanced in medicine, performing skull surgeries successfully and with high survival rates.
The effects on their health was that widespread epidemics of viruses broke out like smallpox, tuberculosis, and typhus. This happened because an impact of the industrial revolution was rapid urbanization, which caused villages and towns to swell, overpopulating different places and making them hotbeds of disease and depredation. This was caused by the expanding industry swelling small villages
Hope this helps!! :))
Probably very stressful and very difficult
Explanation:
The gains achieved by the White minority in the first four decades of the 20th century were, by the 1940s, increasingly under threat however, as African resistance to the racially based system rapidly escalated. This crisis was brought to a head by the continuing decline of the reserve economies. Full proletarianisation in South Africa, would threaten the migrant labour system upon which White profitability depended. This crisis coincided with rapid secondary industrialisation and a substantial growth of urban African populations, as well as growing trade union activity and rising African working class militancy. These developments were threatening not only the conditions for accumulation but White political hegemony itself.
