stira [4]

Answer:

If President Lincoln hadn't been assassinated, I believe that Reconstruction and the post-war era would have been more historically positive and ambitious. I think Lincoln would have achieved more things politically and socially for America, and would have done more to fight against many injustices in this country. Andrew Johnson did not have a positive presidency, says his impeachment. Lincoln had plans, but Andrew Johnson created policies and actions that went against the Republican Party and angered many, like his pardoning of Southerners. Lincoln would have continued to be a great figure for his party and I believe would have provided more as leadership than Johnson. If he was not assassinated, I believe that Lincoln would have continued his legacy and his fight for justice in America.

The British defeat demonstrated that it wouldn't be easy for the English to extend their control over the colonies.

Answer:

1) Czar you would not be happy about the revolvolution as it was supposed to remove his power. As workers you would be happy, and hope for some better rights and living conditions. The soldiers were probably tired of war, and maybe wanted to come back home.

2) A treaty should try and bring peace and stability. A classic example is the treaty of versailles where it is a cause of WW2, it broke the german economy and country with the restriction. Maybe if the treaty were better for Germany we may not have had WW2.

3) If you were germany you would be angry that all the blame is put on you. You will find it unfair you have to pay a big amount of money to the other countries. The treaty feels like a big hard push for Germany, and is a reason WW2 started, and how Hitler managed to grab the power in Germany.
