Answer:
The Russian Revolution happened in 1917. 
Explanation:
The Russian Revolution of 1917 was an important event in twentieth-century world history. France's state revolution in 1789 AD affected Europe's life on a deeper level by propagating the spirit of freedom, equality and brotherhood. The pervasiveness of the Russian Revolution was much broader than all the political events so far. 
This revolution not only brought an end to autocratic, monocratic, autocratic, zarchic rule, but ended the economic and social power of the elite landlords, feudalists, capitalists etc. and established the first power of workers and peasants in the world.
 
        
             
        
        
        
Hernan Cortes (1485-1547) was a Spanish colonizer and conqueror, who leaded the conquest of the Mexican territories, that started in 1519 with the occupation of Veracruz. The tales about the sacking of the Mexican capital, Tenochtitlan, are still legendary nowadays. 
After the takeover of Veracruz, Cortes gave the order of sinking his own ships (it was thought they were burnt, but nowadays that hypothesis is being questioned). Anyway, he destroyed his ships on purpouse to force his men to go forward and conquer the New World, both in the militar and spiritual (goal of spreading the Christian religion) dimensions. 
- Agreement with his decision: of course it is an incredibly effective manner of ensuring that his men would be motivated to conquer the territory, mainly because they did not have an alternative choice. They had to become rulers there or be lost in the middle of unknown lands. It can be claimed how the ultimate goal justifies the means. 
- Disagreement with the decision: it can be argued how unethical is that he prevented his men from deciding if they wanted to participate or not on the mission. He eliminated the choice.

<span>A Confederation. Despite the actual grouping of states into one "unit", the idea of a confederacy is to let the states essentially rule for themselves.Sovereign simply means self-ruling which is what each state would follow under union beliefs.There is no established law of the land for any unions as it would defeat the purpose.</span>
