THG District 13
District 13
Prior to the Dark Days war, District 13 worked in nuclear technology and mined graphite. During the Dark Days they were one of the major forces of the rebellion. Near the end of the Dark Days they managed to take control of the nuclear arsenal. District 13 was supposedly bombed and destroyed before the first annual Hunger Games at the end of the Dark Days war, but it is hinted and later confirmed in Catching Fire that they have survived, and in Mockingjay it's confirmed that District 13 literally became an underground district when the population retreated to bunkers. The Capitol has spread the story that District 13 was destroyed after the Capitol and District 13 agreed to leave each other alone since District 13 made nuclear weapons and the Capitol didn't want a nuclear war. Also, this underground district has its own farms that they survive on after the Capitol destroyed everything above ground so as not to arouse suspicion. This was something that, according to Katniss, the Capitol had underestimated.
