How to explain importance
Importance is a key second-order concept in history
Second-order concepts allow you to:
Understand history
Have a complex explanation
Historical importance is often subjective
Each historian brings their own opinion on what events or people are important
Importance is decided using hindsight. An event is considered important if it:
Created new ideas
Directly changed events at the time
Affected large groups of people
Impacted key themes of the time period, such as:
Cold War tensions
US-Soviet relations
Had important long-term impacts that can be seen today
To understand importance, visualise a set of falling dominoes
An important event, development or person changes the direction of all of the dominoes that come after it

Imagine the set of dominos again
An important development, event or person, when taken out of the sequence, stops other dominoes from falling
If it is less important, it does not stop the dominoes from falling

The Soviet takeover of Eastern Europe was important for the development of the Cold War because it showed the spread of communism across Europe (SOC). Stalin wanted to keep control of the countries that the Red Army had liberated during the Second Cold War. He wanted these countries in Eastern Europe to act as a ‘buffer zone’ between the East and West. However, Stalin's methods to create the satellite states were seen as aggressive. For example, during the 1947 elections in Poland, a campaign of violence and intimidation led to the creation of a fully communist government (K). This led to the development of the Cold War because Truman saw the creation of satellite states as a deliberate attempt to spread communism (SOC). The lack of free elections also broke the agreement made at the Yalta Conference (1945). This made the USA feel that they had to increase their involvement in Europe to stop the spread of communism. This resulted in the Truman Doctrine (1947) and the Marshall Plan (1948).
Another reason why the Soviet takeover of Eastern Europe was important for developing the Cold War was that it worsened US-Soviet relations (SOC). From 1940 to 1948. the Soviet Union has created an 'Eastern Bloc' of communist countries from East Germany to Bulgaria. This had formed a political divide across Europe (K). This developed the Cold War because it looked to the USA as the Soviet Union had created an armed border between the Soviet Union and the West. This inspired Churchill's 'Iron Curtain' speech in 1946. This called the Soviet Union a threat to freedom and peace. The speech led to even greater tensions between the USA and the Soviet Union, leading to a build-up of military forces by both sides (SOC).

SALT 2 was important for US-Soviet relations in the 1970s because it eased the arms race between the two countries (SOC). In 1974, negotiations began for SALT 2, to build upon the success of SALT 1. The treaty was not completed until 1979. SALT 2 agreed to ban the further development of new nuclear technology such as MIRVs and to have equal limits for strategic bombers and missile launchers (K). This helped to improve US-Soviet relations because it showed a continued commitment by both sides to limit their nuclear technology (SOC). This reduced the military threat posed by the USA and the Soviet Union, leading to more opportunities to pursue a better diplomatic relationship. Therefore, SALT 2 continued the progress in the limitation of nuclear weapons between the USA and the Soviet Union.
However, it could be argued that SALT 2 had a limited impact on US-Soviet relations because of other world issues (SOC). By 1979, US-Soviet relations had worsened. Democrats and Republicans did not want to pass SALT 2. The US politicians believed SALT 2 gave the Soviet Union too much power. In addition, the actions of the Soviet Union became more aggressive. In December 1979, the Soviet Union invaded Afghanistan (K). This meant that SALT 2 never received ratification from the US Senate. As a result, the treaty was never upheld by either the USA or the Soviet Union. This means that it had limited importance on their relations. The progress made in their relationship during the period of détente had been destroyed before SALT 2 could make a difference. Therefore, if the USA and the Soviet Union had agreed on SALT 2 earlier, it would have had a bigger impact on their relationship (SOC).
