Why couldn’t the thirteen united states fight for independence against britain before the articles of confederation? they couldn’t raise a national army.
they needed to be able to enforce laws.
they couldn’t declare war.
they needed military strength.

the answer is:

they couldn’t raise a national army.

if you have no nation, how could you raise a national army? that would be a civil war, not an independence war, the states neede to first form a nation together and then they could fight for independende.

in 1891, the people's party (also known as the populist party, or the populists) was formed as a political party representing the interests of the nation's agricultural sector. the farmer's alliance was a major part of the populist coalition.

i think the answer is a and i hope this ; ))
