San Martín's strategy to consolidate independence

San Martín's strategy to consolidate independence  of Argentina was expelling Spaniards from neighboring countries.

Explanation:

Jose de San Martin was the main liberator of Argentina and the southern part of South America during the 1810s and 1820s. It was a military man born in Argentina, at that time the Viceroyalty of the Rio de la Plata colony, who had been educated in Spain and had fought for this country in the Napoleonic wars. Therefore, he was an experienced warrior who, once noted of the independence movement, decided to return to his homeland to lead the troops. His first battle was in San Lorenzo, in February 1813, followed by other iconic contests until on July 9, 1816, Argentina declared its independence from Spain.

But San Martin knew that, if they did not cooperate with neighboring countries, the Spanish would win and return to Argentine territory. For this reason, he organized the Army of the Andes to liberate Chile, which he achieved in 1818 after the Battle of Maipu.

Later, he continued with his army to the north, liberating Peru in 1821 and leaving the command of the South American independence effort to Simon Bolivar in 1822.
