What were the Federalist attitudes towards the national government in 1870's?Who were leaders and the supporters of the two parties?
I dont seem to understand what the question means when speaking of National Government.Who was the National Government?
First of all, 1870s can't be right -- there were no Federalists by then. I think you probably mean 1780s.
The national government means what we often call the federal government or the government in Washington DC. That is as opposed to the governments of the individual states.
The Federalists were in favor of having the national government be very powerful. They thought it ought to have more power and the state governments should have less. The Federalists were led by people like Alexander Hamilton. The Democratic-Republicans were led by Thomas Jefferson.
The Federalists had lost all power in the US government by 1816. Their last leaders included Alexander Hamilton and John Adams, who was the only Federalist president.
As already said, the Democratic-Repulicans were led by Thomas Jefferson, who would become the 3rd US President. The Dem-Rep. wanted a small national government and more state power. I believe that this is why they gained power in the 1800's.
