True or false: kings were able to defend themselves from invasions from vikings?

The correct answer is - False.

During the peak of the Viking's military power, the kings of the other nations that faced them just weren't able to defend their territories from them. The Vikings were excellent warriors, tall, strong, and had terrifying weaponry. The Vikings were so successful in their invasions, that apart from gaining lot of territory, mostly coastal areas (because it suited their lifestyle), there were kings that were actually paying the Viking warriors to protect them from other invaders, or even had a personal guard of Vikings around them, as was the example with Byzantium.

there's multiple reasons why the conquistadors were so successful in colonizing central america, and some of them are:

- they were seen as gods;

at the beginning, the spanish settlers were seen by the natives as gods, and this was mainly due to their white skin, and the way they came with their boats.

- possessed superior weaponry;

the spanish had gunpowder and guns, as well as cannons, while the natives did not had any fire weapons.

- made cleaver alliances;

they used the situation of tribes hating each other, so they made alliances with some of them which served them very well.

- brought diseases;

the native people were not immune to certain diseases the europeans brought with them, so they were dying from seeming harmless things for european standards.
