Nomadic people initially inhabited the land of Argentina but the main two tribes of the country were Diaguita that inhabited the northern part of the country and Guarani that hailed in southern and eastern parts of the country. They were agricultural civilizations and the major crop during those times was maize.
The people of Argentina are known to have resisted a lot of foreign elements from entering their country. Juan De Solis, the first Spanish who landed in Argentina was killed in 1516 but later in the sixteenth century the country fell to Spain. Introduction of various diseases from Europe further weakened the people of Argentina. But throughout their rule, the Spanish empire mostly neglected the country. The British attacked the country in 1806 and 1807 but could not turn the table to the Spanish empire. When the French took Spain, Argentina also succumbed to the captivity of the new ruler, as the Spanish viceroyalty was highly unpopular with the locals. By 1816, a party of separatists declared country's independence that led to bitter struggle between the Unitarists and the Federalists.
