Charles Manson: Cult Leader and Criminal

Charles Milles Manson (born November 12, 1934) was an American criminal who led what became known as the Manson Family, a quasi-commune that arose in California in the late 1960s.

Understanding the Narrative Genre

The narrative is the story of a series of events told by a fictitious entity called the narrator. The narrative genre is manifested in two major ways: the short story (with few characters, little description, and a focus on the outcome) and the novel. In the communication process of the narrative, there is a real sender (author) and a dummy issuer (narrator), who creates a fictional world delivered to the recipient.

Historical Narrative Forms

• Epic Poetry: Oral songs that narrate the exploits of warriors or gods.
• Epic: Narrative poems that tell of human actions and characters worthy of being remembered (e.g., La Araucana, The Odyssey).
• Song of Deeds: Medieval literary works that tell the heroic legends of a village

How Did Castile Evolve?

Castile's Rise

Under the Caliphate of Cordoba, the Muslims attacked Leon. At the same time, Castile became Muslim independent. Castile provided defense against attacks from the valley of the River Ebro. It was divided into counties under the Count Fernan Gonzalez (930–970).

Leon began to decline at the end of the 10th century. This increased the power of the counts of the kings of Castile and Navarre. In 1035, Castile became an independent kingdom.

The Pyrenean Region

The Pyrenean region formed the Spanish March within the Carolingian Empire. In the 9th century, the Carolingian Empire dissolved. Three different independent regions were formed: Navarre, Aragon, and the Catalan counties.
