Soviet period

The city began to industrialize in the 1920s and 1930s.

Violating the Molotov–Ribbentrop Pact, Nazi Germany invaded the Soviet Union in June 1941. The government worked to relocate factories from western Russia and Ukraine to Tashkent to preserve the Soviet industrial capacity. This led to great increase in industry during World War II.

It also evacuated most of the German communist emigres to Tashkent. The Russian population increased dramatically; evacuees from the war zones increased the total population of Tashkent to well over a million. Russians and Ukrainians eventually comprised more than half of the total residents of Tashkent. Many of the former refugees stayed in Tashkent to live after the war, rather than return to former homes.

During the postwar period, the Soviet Union established numerous scientific and engineering facilities in Tashkent.

On 10 January 1966, then Indian Prime Minister Lal Bahadur Shastri and Pakistan President Ayub Khan signed a pact in Tashkent with Soviet Premier Alexei Kosygin as the mediator to resolve the terms of peace after the Indo-Pakistani War of 1965. On the next day, Shastri died suddenly, reportedly due to a heart attack. It is widely speculated that Shastri was killed by poisoning the water he drank.

Much of Tashkent's old city was destroyed by a powerful earthquake on 26 April 1966. More than 300,000 residents were left homeless, and some 78,000 poorly engineered homes were destroyed, mainly in the densely populated areas of the old city where traditional adobe housing predominated. The Soviet republics, and some other countries, such as Finland, sent "battalions of fraternal peoples" and urban planners to help rebuild devastated Tashkent.

Tashkent was rebuilt as a model Soviet city with wide streets planted with shade trees, parks, immense plazas for parades, fountains, monuments, and acres of apartment blocks. The Tashkent Metro was also built during this time. About 100,000 new homes were built by 1970, but the builders occupied many, rather than the homeless residents of Tashkent. Further development in the following years increased the size of the city with major new developments in the Chilonzor area, north-east and south-east of the city.

At the time of the collapse of the Soviet Union in 1991, Tashkent was the fourth-largest city in the USSR and a center of learning in the fields of science and engineering.

Due to the 1966 earthquake and the Soviet redevelopment, little architectural heritage has survived of Tashkent's ancient history. Few structures mark its significance as a trading point on the historic Silk Road.

Such countries of the Soviet Union as Azerbaijan and Armenia, Kazakhstan and Georgia, Belarus and Kyrgyzstan, Turkmenistan and Tajikistan, Latvia, Moldova, Estonia helped restore the city after the earthquake and erected many modern buildings.
