I think you missed quite a few examples of armed citizenry overthrowing a tyrannical government, what about the French Revolution, the Russian Revolution, or the failed Russian occupation of Afghanistan in the 80s? Or the Cuban Revolution or the Vietnam War? And what about the Chinese Revolution, there was a significant amount of the peasant class who fought for Mao.

While civil society was disarmed throughout most of China’s history, this did not prevent Chinese farmers from rising up time and again with whatever they had in their hands. The Chinese term jiegan erqi (rise up with bamboo sticks) was created to describe the peasant rebellion during the Qin dynasty in particular and other peasant rebellions in general when Chinese farmers, under the duress of social injustice, rose up, using anything they could lay their hands on as weapons. However, during the Great Leap Forward, the Chinese population was more armed than ever. That was the time when Mao called for large-scale organization of militia divisions (daban minbingshi). Young villagers in production teams were organized into militia platoons. In each production brigade there was a militia company. At the commune level, there were militia battalions. The department of military affairs in the county government was in charge of arming and training the militia. Chinese farmers worked in the fields with their rifles stacked nearby during the Great Leap Forward years.”

Oh and aren’t you forgetting the American Revolution? We had no standing army at the onset of the revolution and our troops in the beginning were mostly green farmers merchants and tradesmen. That was a majority of our troops just regular citizens who operated independently as militias through the early part of the war defending their homes and utilising guerrilla tactics to thin the well trained professional army of the British. In late 1774 a vote was taken to build a Continental Army contingent on the 13 states consent since the states had right of conscription. Remember it was British attempts to confiscate guns ammunition and gun powder that sparked BOTH the battles of Lexington and Concord. The British knew that disarming the populace would quell the uprising it was a common tactic used throughout the British empire (see Colonial India post first Revolution 1857) when the Brits began gun confiscation en masse.

I’ll close with this very succinct quote from Hitler who used strict gun control laws and the universal gun registration list to disarm the Jews (many of which fought along side the Germans in WW1) round up the guns of his political rivals and ensure only Nazi supporters had guns.

The most foolish mistake we could possibly make would be to allow the subject races to possess arms. History shows that all conquerors who have allowed the subject races to carry arms have prepared their own downfall by so doing. Indeed, I would go so far as to say that the supply of arms to the underdogs is a sine qua non for the overthrow of any sovereignty.” -Adolf Hitler
