Sectionalism was very much a part of the Missouri Compromise, with two main sections of the country -- North vs. South -- divided over the issue of slavery.
The Missouri Compromise (1820) admitted Missouri into the Union as a slave state with Maine being added at the same time as a free state, to keep the balance of slave and free states equal. The Missouri Compromise also prohibited any future slave states north of the latitude line 36 1/2 degrees north of the equator in territories of the Louisiana Purchase, with the exception of Missouri (north of that line) being admitted as a slave state.
A couple decades later, that sectional debate was sparked still further by the acquisition of lands from Mexico after the Mexican-American War. The Mexican Cession was the large region of land that Mexico ceded to the United States in the Treaty of Guadalupe Hidalgo in 1848. It included territory that would later become the states of California, Nevada, Utah, and parts of what would become Arizona, New Mexico, Colorado and Wyoming. The Mexican Cession reignited tension on the issue of slave-holding states vs. free states. Since the Missouri Compromise had specified only the Louisiana Purchase lands with its 36 1/2 degrees latitude dividing line, new debate arose over whether territories in the Mexican Cession territory would be slave or free states.
Answer:
On June 24, 1914 Franz Ferdinand, archduke of Austria-Hungary, was visiting the city of Sarajevo (province of Bosnia Herzegovina). For many people, the visit was considered a provocation. For example, for young Serbian nationalists who wanted Serbia to recover the province of Bosnia-Herzegovina.
Several went out to protest and one of the young men threw a grenade at the vehicle in which Franz Ferdinand and his wife were going. When the grenade exploded several people were injured. The imperial couple had no injuries but they canceled their tour. Instead, they decided to go to the hospital to visit an officer who had been injured, and during the trip they were killed.
This murder unleashed a series of protests and a month later, on July 28, Austria-Hungary declared war on Serbia. Chaos grew like a snowball. Russia got involved as it had alliances with Serbia. Germany, an ally of Austria-Hungary, declared war on Russia. The United Kingdom declared war on Germany, after the Germans invaded Belgium.
This story led to the First World War that changed the direction of Europe.
Darius Was defeated by the Greeks at the Bay of Marathon, Xerxes Was defeated by the Greeks at the Bay of Salamis, Cambyses One of the fewgenerals in history to ever conquer and occupy Egypt, Cyrus Respected the customs and religion of the people he conquered.
