After more than twentyten years holding on, the Nationalist started to enter in decline due to a series of factors. The first one being the death of Pedro Velasco from debilitated health on May 5th of 1958. After the loss of the general’s centralizing figure for the Nationalist cause, internal struggles shattered the republic into several warlord states. Since 1960, Russian discredit in the success of a National Republican government in Peru motivated the country to decrease the support for the nation. The shattered republic wasn’t seen with good eyes by Moscow, which chose to focus its support on other regions. Russian support reached its lowest point during the war with Persia . Popular insurgencies also had a key role in the process. Unpleased with the Nationalist government, many revolts happened in cities and in the countryside.
This troublesome situation opened the opportunity for the Loyalist forces to finally start to advance over the Nationalist territory. In a process of five years, most of the former National Republic was reconquered.
