Why was it hard to get laws passed under the articles of confederation?

States needed to have a 2/3 majority for laws to pass.

Explanation:

The Articles of Confederation (the first written U.S. Constitution) was characterized for establishing a very weak government consisting of a Congress only and with few enforcement powers, and for granting "sovereignty, freedom and independence" to the states. One of the weaknesses it had was that it required 2/3 of states votes (9 of the 13 states) in order to pass any significant legislation, which limited the governmental power and made it difficult to make changes and pass laws that improved the newly born nation.

on november 6 and 7, 1917 (or october 24 and 25 on the julian calendar, which is why the event is often referred to as the october revolution), leftist revolutionaries led by bolshevik party leader vladimir lenin launched a nearly bloodless coup d'état against the duma's provisional government.
