From 1607 to 1865, the U.S. underwent major changes, most of which still have an impact on the modern America. It is notable that, during that time, America had undergone several wars, which significantly affected the U.S. economy, as well as its relationship with international community (Robert 34). The most notable were the Revolutionary War against the British in 1775, the War of 1812, Black Hawk War and the American Civil War. Out of these wars, the most prominent one was the American Civil War, which took place after eleven states from the South broke from those in the North, forming a new country referred as the Confederate States of America.
After the assassination of Abraham Lincoln, the new U.S. President Andrew Johnson was forced to undertake a process of Reconstruction in order to reclaim the U.S. image both at home and abroad. This had enormous effect not only on the U.S., but also across the globe. First, the 13th, 14th, and 15th Amendments of the U.S. constitution was made, thus freeing the slave and making it possible to vote, an aspect that significantly changed the political atmosphere. To punish the South for participating in the Civil War was difficult for the Congress, which was run by “Radical Republicans” (Foner 23). Among other important achievements was the possibility for people to possess their own land in the new states..
Reconstruction also improved the relationship between the U.S. and neighboring states. For instance, as a result of improvement of regional relationships, there was movement of people from Eastern Europe, China and the rest of European Region to cities such as Chicago, Boston and New York in order to find a job. One of the ways in which Reconstruction succeed was the improvement of relationship between the U.S. and its neighbors, the amendment of the constitution, thus ending slavery. Some of the notable failures include the inability to solve conflicts concerning land, which occurred among the native Indians and the White settlers, as a result of many the Indians were dead. Generally, the process of Reconstruction remains one of the most remarkable phases in the U.S. history. The consequence of it was the equality, the factor which has ensured sustainability of the U.S. economy.
