Valle del Cauca is a department of Colombia. It is in the western side of the country, facing the Pacific Ocean, and it is considered one of the most important departments in the Republic of Colombia. Its capital is Santiago de Cali.
Palinological analysis performed by experts have determined that during the Superior Pleistocene some (40.000 - 10.500 years ago), the valleys of "El Dorado" and "Alto Calima" had Andean forest and Sub Andean vegetation. The discovery of projectiles indicated that there were communities of hunter-gatherers to the end of the Pleistocene and the beginning of the Holocene.Hunter gatherer societies (8.000-3.000 BC)
The extinguishing of the Pleistocenic megafauna in the beginning of the Holocene pushes humans to adapt to their new environment, making them turn into hunter-gatherers. In the lower basin of the Calima River (Sauzalito River, El Recreo River and El Pital River) archaeologists found the oldest hunter-gatherers vestiges that inhabited the Valley of the Cauca River. According to these, in 5000 BC these societies already had some level of primitive agriculture and cultivated maize. There is little information about the years between 3000 and 1500 BC.
In 1500 BC the first Agricultural-Pottery society appears extending along the Calima River (in what is nowadays the towns of Restrepo and Darien called Ilama Culture. Its society had a social structure of Cacicazgos (chiefdoms) that prevailed until the arrival of the Spaniards. The economy of Ilama was based in migratory agriculture using maize, yuca, beans, hunting, fishing, textile confectioning and metallurgy. The Chief or "Cacique" was the head of the settlement and also had "chamanes" (spiritual leaders), warriors, farmers, hunters, pottery men, and goldsmiths. By 100 AD the Ilamas had developed into the Yotoco Culture which expanded the region of the Ilamas further into the Cauca River and the Pacific Ocean and to the south to the region of what is now the city of Cali.
The Yotocos prevailed in the region until 1200 AD and were a highly stratified society headed by caciques which managed several settlements. The population had increased, forcing them to develop effective agricultural techniques to feed its population which also improved the techniques on pottery and metal works. The agriculture of the Yotocos was more varied than that of the Ilamas and was based on maize, yuca, beans, arracacha, achiote among others. The Yotoco started declining in the 6th Century AD.
This archeological period is called Late and is divided into Late Period I (6th to 13th centuries) and Late Period II (14th to 16th Centuries). In the Late period I the region of Valle del Cauca was inhabited by the Early Sonso Culture, Bolo, Sachamate and La Llanada. During the Late Period II the region was inhabited by the Late Sonso Culture, Pichinde, Buga and Quebrada Seca. Their development is attributed to the growth of population and the almost all the settlers in the area became subject to the rule of one main Cacique.
The first Spanish explorers arrived in the area after founding the village of Popayan in an expedition that came from Quito and was headed by Sebastián de Belalcázar. In the Valle del Cauca the explorers founded the village of Villa de Ampudia named after one of them called Juan de Ampudia. By orders of Belalcazar the village is then moved to the Riviera of the Cauca River within the Gorrones Indigenous peoples territory. In 1536 a Captain last named Muñoz orders the city to be moved to the Lili Valley were the Village of Cali was founded on July 25 of that same year.
Another Spanish explorer coming from the village of Cartagena de Indias named Juan de Vadillo commanded a second group of explorers and entered Cali on December 23, 1538, but he returned to Cartagena leaving many of his men behind including Pedro Cieza de León.
A third group of explorers led by Almirant Jorge Robledo under orders of Lorenzo de Aldana advanced to the North of the Valle del Cauca and founded the villages of Anserma (now part of Caldas Department) on August 15, 1539; Cartago on August 9, 1540 and the village of Antioquia on November 25, 1541 and under command of Pascual de Andagoya who arrived from Panama to Cali with a fourth group of explorers.
The Department of Valle del Cauca was created by decree number 340 of April 16, 1910 which also created 12 other departments for Colombia. The Valle del Cauca Department was a result of the union of four former departments; Cartago, Buga, and Cali.
The government of Valle del Cauca is similarly set up as the Government of Colombia in which there are three branches of power; judicial, executive and legislative with control institutions at government level. The executive branch in Valle del Department is represented by the Governor of Valle del Cauca Department, the legislative branch is represented by the Department Assembly of Valle del Cauca and its deputies and the judicial is represented by the four department level of the Judicial Branch of Colombia; Superior Tribunal of Cali, Penal Court of the Circuit of Cali, the Administrative Tribunal of Valle del Cauca and Superior Military Tribunal for military cases. Valle del Cauca Department has 42 municipalities, each one having a mayor which is a popularly elected representative of the governor.
