Guatemalan Genocide

The Genocide in Guatemala happened between the years 1981–1983.
Guatemala was known as the for it remarkable Mayan civilization, which prospered throughout the 10th century AD. At this time new Spanish explorers conquered this region in the 16th century, the Mayans became slaves in their own homeland. They force to become the inferior people at this point in time they are still known as the unequal and lowerclass majority of Guatemala's population.

In the early 1960s, a civil war broke out due to inequalities existing in the economic and political life. In the 1970s, the Mayan people began participating in protests against the repressive government, 

demanding greater equality and inclusion of the Mayan language and culture. Being controlled by the military ruler Efraín Ríos Montt, they went throughout a campaign in 1982 aimed at massacring thousands of indigenous peasants. In an operation called “Operation Sofia”, they found evidence that should how there were “acts of genocide against groups of Mayan people.”

As read in files, "the army destroyed 626 villages, killed or “disappeared” more than 200,000 people and displaced an additional 1.5 million, while more than 150,000 were driven to seek refuge in Mexico." 

There were my cases where many people do not know what happens to loved ones because there were forced disappearance policies which included "secretly arresting or abducting people, who were often killed and buried in unmarked graves."  The government also put in place a "scorched earth policy, destroying and burning buildings and crops, slaughtering livestock, fouling water supplies and violating sacred places and cultural symbols." This almost made it impossible to live anywhere as no matter one did to services it became inhabitable. Most of the action was by special units known as the Kaibiles who were private death squads. The violence faced by the Mayan people peaked between 1978 and 1986. Even Catholic priests and nuns also often faced violence no matter the cause as they supported and protected the rights of the Mayan people.
