What does a republicanism mean?

Answer 1

A Republican is a member of one of the two major political parties in the United States. Being a Republican usually means that you are conservative and anti-big government, at least at the grass-roots level. Unfortunately, those views do not appear to be reflected at the top of the party. Outside of the United States, a republican is someone who seeks or hopes for the end of monarchy. Within the United States, a Republican is someone who thinks that although his Party base includes both the most rabidly ignorant, violently xenophobic illiberals and the obscenely wealthy corporation owners who betray American working people to the Chinese, it still somehow can lay claim to a higher moral ground and truer patriotism than any other Party.

Answer 2

says that the states will help other states in defense incase of an attack
A republic is normally a system of government containing a Legislature (a Parliament and/or "House of Representatives" and/or a Senate etc) to debate and create laws, an Executive to govern day to day and make policys and to put before the Legislature and a Judiciary to enforce the laws and balance out the others.

Key to this is that both the Executive and Legislature are elected so answer to voters and they then appoint the Judiciary in some way but once appointed the Judges don't actually have to listen to anyone so make decisions based solely on law.

The exact form of the branches and the powers of each varies depending on the country.
