The main reason is that city states were becoming increasingly wealthy
The nation was not unified and every city was a state for itself. This meant that they didn't have to think about the rest of the land and they focused on trading and getting richer and richer. The rich lords and ladies liked art and employed numerous artists to do commission work or to make the state a better place or similar things.
Answer:
Before imperialism there was isolationism, which according to page 608 of the textbook was “the belief that America should stand apart, stay out of foreign wars, and avoid excessive political or economic involvement in foreign affairs”. This worked until 1846 when the US went to war with Mexico and gained four new states. With this new sense of power people begin to lean towards imperialism. Imperialism is “the policy or action by which one country controls another country or territory”. In 1893 there was an economic depression that led to an oversupply of manufactured goods that weren’t moving in America. In order to move these goods, businessman begin looking abroad. They believed that America needed to join the imperial competition and many military and political leaders agreed. A naval officer named Alfred Mahan published a book in which he wrote that in order for America to be a great world power we will need a great navy. This new imperial rule for the for America seemed to be justified by the idea of social Darwinism, which is basically just survival of the fittest.

Answer:

Explanation:
The Articles of Confederation were the newly formed country of the USA's government set. It was mainly written by John Dickinson, a delegate from Delaware. It placed 13 laws that controlled state and country governments.
However, these laws put main power on the state governments while giving the central government almost none. This was due to the fact that they had just gone through a revolution against Britain, and they were controlled by a monarchy. The Americans were afraid that with a strong central government, it would become a monarchy just like Britain. They wanted to avoid this due to the taxes that a monarchy placed on them.
This led to a weak central government which caused all the states to act as independent countries. It also lead to different currencies in each state, which was a problem for farmers, as they couldn't pay their debts from money earned in the war.
Farmers were sometimes put in prison for not paying their debts, and they lost their farms. This caused Shays Rebellion, which called for a new system where the central government had more power.
This system was revised into the Constitution we have today.
Hope this helped!
