Genocide occurred in guatemala in 1981–1983 because
the guatemalans wouldn’t give mayans back the land they stole.
the guatemalans had not trusted the mayans for many centuries.
the mayans took over the government and massacred guatemalans.
the mayans demanded to be part of the guatemalan government.

The correct option is: "the Mayans demanded to be part of the Guatemalan government."

The Mayan genocide - also called Guatemalan genocide - would have occurred in Guatemala in the oil region of the Ixil Triangle in the 1980s -pecifically between 1981 and 1983- and would have developed during the period of the Guatemalan Civil War (1960-1996). ) in which, according to the report "Memory of Silence" of the Commission for Historical Clarification-named by the United Nations to investigate the historical events of that civil war-an approximate of two hundred thousand disappeared / murdered persons and, according to other analysts, less than one hundred thousand victims.
