Why didn't the Republic have an army, and also: 1) How centralized was the power of the Republic? IE was it centralized in the way the US is now, where the States must ultimately obey federal law, or was it closer to the US as it was under the Articles of Confederation? 2) Was the Chancellor (pre Palpatine) closer in power and executive ability to a US President or to a British Prime Minister? 3) Why did the Republic come together in the first place? 4) How were Republic laws enforced across tens of thousands of planets without an army? 5) Prior to the events of TPM, how important was Naboo in terms of the Republic? 6) Were there any Galactic rebellions prior to the Separatist movement?
