If these weren't available, the corpses would be left to rot or would be burned. Such examples have been found scattered throughout Europe. Spanish Civil War There are over 2,000 known mass graves throughout Spain from the Spanish Civil War wherein an estimated 500,000 people died between 1936 and 1939, and approximately 135,000 were killed after the war ended. Exhumations are ongoing. Some are conducted on the basis of information given in witnesses' and relatives' testimonies to the Asociación para la Recuperación de la Memoria Histórica (ARMH). These testimonies serve the purpose of helping geophysicists, archaeologists and forensic scientists to locate graves in order to identify bodies and allow families to rebury their relatives. In the summer of 2008, information from these testimonies was used to unearth a 4 meter long square grave containing five skeletons near the town of San Juan del Monte. These five remains are believed to be of people that were kidnapped and killed after the July 18, 1936 military coup. Another mass grave from the Spanish Civil War was found using Ground Penetrating Radar (GPR). Eyewitness accounts identified two potential locations for an unmarked grave in mountains of Lena in Northern Spain. Both sites were examined and an unmarked mass grave of approximately 1 meter by 5 meters was found. 2nd Sino Japanese War Korean War Approximately 100,000–200,000 civilians were killed at the start of the Korean War. These people were flagged by the government of South Korea for potentially collaborating with or sympathizing with North Korea. They were arrested and subsequently executed without trial. The sites where the massacres occurred were forbidden to the public. The bodies were considered to be traitors and the act of associating with them was considered treasonous. Despite this, families retrieved bodies from the shallow forbidden mass graves at the massacre sites. In 1956, bereaved families and villagers exhumed over 100 decomposed and unidentifiable bodies, ensuring that the complete human skeleton was intact. Each exhumed body was buried in its own "nameless grave" in a cemetery on Jeju Island. There is a granite memorial within the cemetery which bears the cemetery's local name, "Graves of One Hundred Ancestors and One Descendant." This name functions to express the opposite of how the genealogy should be as typically many descendants derive from one ancestor. 1973 Chilean coup d'état The Chilean military coup against President Salvador Allende occurred on September 11, 1973.
