How the cold war begins?

The cold war began in June 1950. The first military action of this war began when the Soviet-backed North Korean People's Army invaded its pro-Western neighbor to the south. As a result, American officials feared this was the first step in a communist campaign to take over the world and deemed that nonintervention was not an option.

The term "cold" is used because there was no large-scale fighting directly between the two superpowers, but they each supported major regional conflicts known as proxy wars.

an effect of the steamboat's popularity was that people began building canals in the united states and europe. this was done to find another way to transport goods across the country and in that time, transportation using the river was very slow and dangerous. it depended entirely on manpower and the current of the river. that all changed in the late 1700's when steamboats were introduced. they soon revolutionized travel and trade through the river and dominated the waterways. eventually, other means of transportation took over from the steamboats, but there was a time that they the united states to expand to the west.
