How did democracy and other forms of government develop in Greece?

it started in 5th Century BCE by Cleisthenes

Explanation:

Cleisthenes Introduced the concept of demokratia. Which can be translated as "People power". It's a concept that he developed as an alternative from a monarchy system which often put one king in an absolute position of power. Many of them ended up becoming tryannical and supress his own people.

To create a fairer society, he proposed a new concept of government, where the people were involved in the creation of laws and government program.

He elected a group of people with a lottery (purely based on luck) in order to act as "jurors", which is basically the representative of the people. The jurors can directly cast out their vote to determine which type of legislations should be created in their community.

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.
