The development of the United States was shaped by three major historical periods: the creation of the Amerikanische Verfassung 1787, the Amerikanischer Bürgerkrieg Zusammenfassung, and the era of Manifest Destiny USA.
The Verfassung USA Original established America's fundamental governing principles in 1787, replacing the earlier Articles of Confederation. This landmark document, officially enacted in Amerikanische Verfassung 1789, created a federal system with three branches of government and included important protections for individual rights. The Constitution's first three articles outlined the separation of powers, with Grundgesetz USA Artikel 1 establishing Congress's legislative authority. This framework proved resilient but was severely tested during the Civil War era.
The Amerikanischer Bürgerkrieg Verlauf (1861-1865) represented a crucial turning point in American history. The conflict between the Union Nordstaaten and the Bürgerkrieg USA Südstaaten centered on states' rights and slavery. Key turning points included the Blutigste Schlacht Amerikanischer Bürgerkrieg at Gettysburg, which helped secure Union victory. The war's aftermath brought the Abschaffung der Sklaverei USA through the 13th Amendment. During this same period, the concept of Manifest Destiny English emerged, promoting American expansion westward. This ideology, often depicted in Manifest Destiny Bild artwork showing Columbia leading settlers west, drove the Westward expansion USA movement. The belief in America's divine right to expand across the continent profoundly influenced 19th-century policy and continues to spark debate about American exceptionalism in Manifest destiny today discussions. This expansion dramatically reshaped the American landscape, as shown in various Bürgerkrieg USA Karte maps of the period, and established the continental United States as we know it.
